Abstract

Type CG-8M is an iron-chromium-nickel-molybdenum alloy with excellent resistance to corrosion by reducing media; however, it is not suitable for use in nitric acid or other strongly oxidizing environments. Its normal microstructure after heat treatment consists of an austenitic matrix in which 15 to 35% ferrite is distributed in the form of discontinuous pools. This ferrite gives the alloy considerable resistance to stress-corrosion cracking and high strength at room and elevated temperatures. Typical uses are in the nuclear, textile and petrochemical industries. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: SS-369. Producer or source: Various stainless steel casting companies.
