AVESTA 254 SMO was developed for use in halide-containing environments. Its high molybdenum content, along with the copper addition, provides a material with excellent resistance to pitting and crevice corrosion as well as good general corrosion resistance, especially in halide-containing acids. In addition, its high nitrogen content results in superior strength when compared with other austenitic stainless steels. Typical applications for Avesta 254 SMO involve seawater contact, scrubbers and high-halide level tanks and piping. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-445. Producer or source: Aluminum alloy mills.

AVESTA 654 SMO is an austenitic stainless steel which due to its high content of molybdenum and nitrogen possesses excellent resistance to pitting and crevice corrosion. It also has very high resistance to general corrosion in acids, especially those containing halide ions. Furthermore, its mechanical strength is high in comparison with conventional austenitic grades. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-552. Producer or source: Avesta Sheffield Inc.

SANDVIK 254 SMO is an aqueous corrosion resistant stainless steel particularly resistant to seawater and chloride media. It is also used in bleach environments with the pulp and paper industry. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-581. Producer or source: Sandvik.

Avesta Polarit 317LMN is a low-carbon, higher-molybdenum austenitic steel frequently used for flue gas desulfurization service. The alloy is a fully austenitic stainless steel with excellent resistance to corrosion in chloride environments and nonoxidizing acids. It is significantly stronger than most low-carbon stainless steels and its structural stability makes for good weldability. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-465. Producer or source: AvestaPolarit AB. Originally published as Avesta Stainless 34LN, October 1985, revised July 2001.

AVESTA 2205 is a ferritic-austenitic duplex stainless steel. It resists stress-corrosion cracking very well and has good pitting and general corrosion resistance. Its high strength and stress-corrosion resisting characteristics are a reflection of its duplex microstructure. Its uses include heat exchangers, desalination plants, and pressure vessels that need good resistance to corrosion. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-472.
