CARPENTER 7-Mo PLUS is a duplex stainless steel of austenite in a ferrite matrix. It is superior to 300 series stainless steels like types 304 and 316 in strength, corrosion, pitting and stress-corrosion cracking resistance (to chlorides). Typical applications are heat exchangers in the chemical and petrochemical industries. 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-608. Producer or source: Carpenter.
