Abstract

SUMITOMO DP8 is a duplex stainless steel. Duplex stainless steels are designed to be economical and reliable for material applications in the production of oil and gas to resist the environments there of carbon dioxide, hydrogen sulfide and chlorides. This family of alloys is also resistant to chloride-ion stress-corrosion cracking. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-571. Producer or source: Sumitomo Metal Industries Ltd.
