“…They offer higher toughness and better weldability than pure ferritic stainless steels and higher strength, better corrosion resistance than pure austenitic stainless steels [1][2][3][4]. Hence they are attractive material for applications where these properties are desired like in off-shore industries, food industries, chemical industries, paper industries [5,6], nuclear industries [7,8] and in structural applications as well [9,10]. DSS can be also used as a material for water tankers to supply fresh drinking water in military areas where fresh water is scarce [11].…”

Duplex Stainless Steels (DSS) and Super Duplex Stainless Steel (SDSS) have excellent integration of mechanical and corrosion properties. However, the formation of intermetallic phases is a major problem in their usage. The mechanical and corrosion properties are deteriorated due to the presence of intermetallic phases. These phases are induced during welding, prolonged exposure to high temperatures, and improper heat treatments. The main emphasis of this review article is on intermetallic phases and their effects on corrosion and mechanical properties. First the effect of various alloying elements on DSS and SDSS has been discussed followed by formation of various intermetallic phases. The intermetallic phases affect impact toughness and corrosion resistance significantly. Their deleterious effect on weldments has also been reviewed.

“…Duplex stainless steel (DSS) is finding increased applications as structural material in critical components of nuclear power plants [1][2][3][4], chemical industries [5,6], oil and gas sectors [7,8], paper and pulp industries [9,10], transportation [11] and other general engineering applications because of higher strength, superior resistance to stress corrosion cracking and better weldability [12]. The excellent combination of mechanical properties and corrosion resistance of duplex stainless steel is obtained from balanced amount of ferrite and austenite in the microstructure.…”

“…A set of modified 316LN-based steels with additions of nitrogen, manganese, copper, and tungsten were produced to obtain materials with improved performance [3,4]. However, limited literature is available on cast steels [5,6] and the role of alloying. The current work will summarize the characterization of the mechanical behavior, microstructure and elemental distribution present in the initial heat of cast stainless steel based on the composition of the wrought 316LN-IG alloy [7], as well as several modified heats based on that initial heat with minor alloying element variations designed to improve austenite stability, alloy strength, and in-reactor performance.…”

Casting of stainless steels is a promising and cost saving way of directly producing large and complex structures, such a shield modules or divertors for the ITER. In the present work, a series of modified high-nitrogen cast stainless steels has been developed and characterized. The steels, based on the cast equivalent of the composition of 316 stainless steel, have increased N (0.14-0.36%) and Mn (2-5.1%) content; copper was added to one of the heats. Mechanical tests were conducted with non-irradiated and 0.7 dpa neutron irradiated specimens. It was established that alloying by nitrogen significantly improves the yield stress of non-irradiated steels and the deformation hardening rate. Manganese tended to decrease yield stress but increased radiation hardening. The role of copper on mechanical properties was negligibly small. Analysis of structure was conducted using SEM-EDS and the nature and compositions of the second phases and inclusions were analyzed in detail. No ferrite formation or significant precipitation were observed in the modified steels. It was shown that the modified steels, compared to reference material (commercial cast 316L steel), had better strength level, exhibit significantly reduced elemental inhomogeneity and only minor second phase formation.
