Abstract:
Duplex stainless steels were first manufactured early in the 20th century, but it was the introduction in the 1970s of the argon-oxygen decarburisation (AOD) steel making process and the addition of nitrogen to these steels, that made the alloys stronger, more weldable and more corrosion resistant. Today, duplex stainless steels can be categorised into four main groups, i.e., “lean”, “standard”, “super”, and “hyper” duplex types. These groups cover a range of compositions and properties, but they all have in common a microstructure consisting of roughly equal proportions of austenite and ferrite, high strength, good toughness and good corrosion resistance, especially to stress corrosion cracking (SCC) compared with similar austenitic stainless steels. Moreover, the development of a duplex stainless-steel microstructure requires lower levels of nickel in the composition than for a corresponding austenitic stainless steel with comparable pitting and crevice corrosion resistance, hence they cost less. This makes duplex stainless steels a very versatile and attractive group of alloys both commercially and technically. There are applications where duplex grades can be used as lower cost through-life options, in preference to coated carbon steels, a range of other stainless steels, and in some cases nickel alloys. This cost benefit is further emphasised if the design engineer can use the higher strength of duplex grades to construct vessels and pipework of lower wall thickness than would be the case if an austenitic grade or nickel alloy was being used. Hence, we find duplex stainless steels are widely used in many industries. In this paper their use in three industrial applications is reviewed, namely marine, heat exchangers, and the chemical and process industries. The corrosion resistance in the relevant fluids is discussed and some case histories highlight both successes and potential problems with duplex alloys in these industries. The paper shows how duplex stainless steels can provide cost-effective solutions in corrosive environments, and why they will be a standard corrosion resistant alloy (CRA) for many industries through the 21st century.

Abstract:
Stainless steels are widely used in the Oil & Gas and chemical process industry. This group of materials is today available in a large variety of alloy compositions, and practically all product forms needed for a construction are available. A historical view and application examples are given on the stainless steel evolution, from the standard grades used in chemical processes to todays most advanced applications in the chemical and oil & gas industry, where demands on reliable and long lasting solutions are necessary. The influence of alloying elements on the properties and manufacturability is described. The chemical industry is a very wide definition of a large group of industries with very different products, from plastics and organic acids to fertilizers, drugs and pesticides. Applications of stainless steels within the chemical industry are described. The first example is organic acids, where the use of high alloyed duplex stainless steels such as UNS S32205 and UNS S32750 have been successful. Another example is phosphoric acid applications, where the aggressiveness of the process solution depends very much on the fluoride and chloride content of the rock phosphate. In sulfuric acid, the material of construction is very much dependent on the acid concentration and temperature. Nitric acid is another common fertilizer acid which is highly oxidizing, and thereby demands stainless steels with high chromium content but with low molybdenum contents. The Oil & Gas industry uses very high quantities of carbon steel and stainless steel in their constructions. The oil wells are defined as sweet when the well contains carbon dioxide and no substantial amounts of hydrogen sulfide, when there is hydrogen sulfide present in the well, the wells are defined as sour. An overview on materials depending on the application is given. In subsea applications, hydraulic control lines (umbilicals) are used for control of valves and for methanol injection in subsea platforms. UNS S32750 is a high strength duplex stainless steel which today is the first choice for umbilicals and has been chosen for a very large amount of umbilical projects worldwide. The newly developed hyper duplex stainless steels with a combination of even higher corrosion resistance and strength are introduced for applications in oil-gas industry. The possibilities with stainless steels are endless, and new alloys are constantly being developed to meet industrial challenges of today and in the future. By choosing the right stainless steel grade, it is possible to find a solution to almost all challenges in the Oil & Gas and Process industry.

Abstract:
The thesis deals with hyper duplex stainless austenitic-ferritic steels and their mechanical and castability properties. The evaluation of resistance to pitting corrosion is divided by PRE values. Steels with a PRE value higher than 48 belong to the group of hyper duplex steels. The theoretical part contains an introduction to the chemical composition, structure and properties of these steels. The practical part is focused on the conditions of tendency to crack castings during solidification and cooling. Furthermore, there is evaluated influence of intermetallic phases on mechanical properties.

Abstract:
Duplex stainless steels (DSS's) are frequently used in oil and gas production and are subsequently subjected to cathodic protection. There is now growing concern about the cathodic evolution of hydrogen produced from this protection system, which may diffuse into the alloy and cause an embrittled condition. DSS's have a microstructure that is a mixture of austenite and ferrite and combines the advantages of these grades, whilst minimising their deficiences. In this research, Zeron 100 DSS was studied in six conditions to investigate the effects of hydrogen embrittlement (HE) on the various strengths and microstructures. The six conditions wer~ as follows: as-received, cold worked, age-hardened (475°C embrittlement), high temperature heat treated, rod and powder. To simulate service environments, 3.5% wt NaCI solution at ambient temperature with an applied potential of -1.1 V (SCE) was used. The effect of pre-charging for up to 550 hours at 80°C was also investigated. Test methods included slow strain rate testing (SSRT), monitoring of transient crack propagation (TCP) using circumferentially notched tensile specimens using a DC potential drop method, acoustic emission CAE) and some conventional bolt loaded fracture mechanics specimens. Test results were correlated with the varying microstructures and environmental conditions and consisted of mechanical properties, threshold crack growth including transient effects and AE data. In this work transgranular cleavage cracks were obtained in the susceptible ferrite phase as a direct result of HE; the depth of these cracks implied a high hydrogen concentration throughout the specimen. The austenite failed by ductile tearing and acted as a physical barrier to the propagation of cleavage cracks. As a result of SSR testing the best material was found to be the powder material; the fine equally dispersed austenite phase caused a lowering of the effective K value. The worst material was the high temperature heat treated type because it contained more ferrite (11:1 72%). The age-hardened material was also susceptible because of the hard and brittle ex' phase. However, regardless of the environment the UTS remained virtua]]y unchanged for each individual material, indicating that most cracking occurred in the post-UTS stage of the test. With the TCP test a lowering of the fracture load was found when an HE environment was used; daldt vs Kq curves were produced, however the DC potential drop equipment could not accurately measure crack growth because of the bridging effect of the austenite phase. The most susceptible microstructures were again the age-hardened and heat treated types. The hydrogen evolution reaction (HER) was also investigated by creating a fresh surface on the as-received DSS and studying the changes in the HER. This work showed that the effect of scratching is irreversible. Also the oxide film can not be totaHy reduced electrochemica]]y and only mechanical methods can remove the oxide films entirely. Fina]]y a means of detecting "475°C embrittlement" of DSS's was investigated using an electrochemical technique in 5M HCI. i-E curves were produced which showed the reactivation of the ferrite and austenite phases in the as-received material. By age-hardening at 475°C the two reactivation peaks merged.

Abstract:
Duplex stainless steel flanges are normally forged to form, as required by the ASTM A182/A182M standard, but may also potentially be machined directly from forged stainless steel bar. In order to evaluate the integrity of such flanges, axisymmetric elastic-plastic finite element models have been developed, considering static effects such as bolt load and internal pressure. Additionally, tensile testing of a sample forged bar (UNS S31803) has been conducted. The stress distribution in a flange during gasket seating and operating conditions has been determined, as well as the degree of plastic strain caused by the bolt loads. The maximum stresses have been found to be around the same values as the minimum yield strength requirement of the studied material (UNS S31803), and the location of the maximum stress concentrations have been identified as the gasket groove. The tensile tests of the forged bar (UNS S31803) have shown that the yield and tensile strength properties are considerably higher than the standardized minimum requirements. The elastic modulus of the forged bar has also been determined, and was found to be lower than anticipated in the axisymmetric models. Some specimens have also been found to exhibit highly non-linear elastic properties.

Abstract:
Three duplex stainless steels (Avesta 2205, Sandvik SAF2507 and Zeron 100) were successfully welded automatically at a range of pressures from 1 to 32bar. The gas tungsten arc (GTA) welding process was chosen as it allows a high degree of control to be exercised during welding. Initial autogenous bead on plate welds established the effects of pressure on the welding process and allowed the process parameters to be determined for subsequent experiments. Analysis of the effects of pressure on the weld thermal cycle showed that at higher pressures the precipitation of phases deleterious to the weld quality was less likely than at ambient pressure. It was also found that the arc melting efficiency increased as the pressure increased, which was taken into account when the process parameters for the joints were selected. A V-butt design with a 'land' on each side was chosen for the joints to counteract any tendency for the welding arc to wander at higher welding pressures. The root welds were performed using pulsed current welding techniques to overcome the difficulties in achieving consistent penetration that were encountered when welding at lower pressures. It was found that by employing standard welding consumables commonly used for welding duplex steels at ambient pressure satisfactory austenite-ferrite phase balances could be achieved in the weld metal at all pressures. Metallographic examination of the welds showed that the joints did not have any microstructural complications that were related to pressure and mechanical testing revealed that, in terms of impact toughness, the weld metal and heat affected zone (HAZ) performed as well as, if not better than, the parent plate material. This work shows that welding of duplex stainless steels using the hyperbaric welding method is a viable option for subsea operations up to a depth of at least 320m, automated hyperbaric welding being advantageous at depths greater than 40m.

Abstract:
The development of high pressure-high temperature oil wells in the U.K.'s north sea province has led to the application of high-strength, corrosion resistant alloys for production tubulars. One such alloy is super-duplex stainless steel (SDSS). The cold-worked material combines high strength with excellent corrosion resistance properties as a result of its chromium, molybdenum, tungsten and nitrogen content. The material's macro properties are a function of its two-phase microstructure made up of roughly equal parts austenite and ferrite. Recent in-service failures of SDSS tubulars have identified gaps in the understanding of the material's properties. The study investigated the link between the microstructure of the material and its mechanical and corrosion behaviours. The results revealed that the microstructure of the material was highly anisotropic and varied through the pipe-wall as a result of manufacturing techniques. A method of measuring the crack resistance of the material was developed, with the results showing that the spatial arrangement of the microstrucure determined the crack resistance of the fracture plane. The properties of ferrite were identified as the limiting factor on the crack resistance of the material. The investigation also revealed that a small difference in chemical composition between the two phases led to the preferential dissolution of ferrite in aqueous oxygen bearing chloride environments.

Abstract:
Duplex Stainless Steels (DSS) have found widespread use in a range of industries, because of their high strength with high resistance to stress corrosion cracking and resistance to sensitization-induced intergranular corrosion. The more high alloyed grades [super DSS] are resistant to oxygenated or chlorinated seawater. Consequently, due to the stable mechanical and corrosion properties after thermal aging for long term service at temperatures below 400°C, duplex stainless steel is used in pipes and components in the primary cooling systems in the PWRs (Pressurized Water Reactors). The investigated material was DSS of grade {UNS S31803 (ASTM A790, ASTM 2205)} in the form of pipe. Each weldment specimen was heat treated at one of the following temperatures: 475°C, 600°C, 700°C, 850°C, 1050°C and 1150°C for 1 hour. The ferrite content and hardness tests were performed along the weldment. The impact test was performed according to the ASTM E23 and the examination of intergranular corrosion susceptibility was performed (ASTM A262 - Practice B). The microstructure investigation was carried out by using the light optical microscopy for etched specimens. The SEM with EDAX was used to detect the microstructural changes due to the heat treatment and after corrosion as well as within the fracture surface of the impact specimens. Slight changes were observed at 475 and 600 °C/1 h conditions as compared to the as received condition, while a little loss in ferrite content was observed at 700°C aging condition. This may be the result of precipitation of different types of secondary phases such as χ-phase, ζ-phase, carbides and nitrides. At 850°C, the observed great loss in ferrite content may be attributed to precipitation of σ-phase with large volume fraction. The solution treatment at 1050 °C/1h condition improved the ferrite content values as a result of decomposition of σ-phase. But the ferrite % value does not return back to its original value at the as received condition. On the other hand, when the solution treatment was done at 1150 °C/1h condition, the ferrite content continued to increase to the as received condition as a result of recovery of δ-ferrite inside the structure.

Abstract:
Super duplex/duplex stainless steel is susceptible to Hydrogen Induced Stress Cracking (HISC) whilst under the influence of Cathodic Protection (CP) systems. Field failure experiences have been reported on super duplex stainless steel components in subsea applications. However, HISC is a non ductile mode of failure caused by combinations of particular conditions associated with hydrogen charging, metallurgical factors of the alloy, stress/strain level and service conditions. DNV RP F112 [4] has been introduced recently and is a guideline for the design of duplex stainless steel components for offshore applications operating under CP systems. Super duplex/duplex stainless steel tubes have been used as components in DUCO umbilical systems for more than 15 years without any failure feedback. A combination of controlling the material microstructure, welding operation design, component stress design, and surface condition design have contributed to this record. This paper describes the design methodology applied by DUCO for the super duplex/duplex umbilical tubes for optimum mitigation against HISC. The influences of the microstructure, stress/strain condition, surface condition and cathodic potential on the seamless super duplex stainless steel (UNS 32750) umbilical tubes resistance to HISC are discussed. Results of laboratory tests using Slow Strain Rate Testing (SSRT), stepwise uni-axial and constant load methods, with reference to offshore oil field application best practice, are presented.
