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.
