JESSOP JS625 is a nickel-chromium-molybdenum-columbium alloy that is well suited for applications where strength and corrosion resistance are required. It has superior strength and toughness at temperatures ranging from cryogenic to 2000 F; also, it has exceptional fatigue strength. It is outstanding in resistance to corrosion either general or localized (pitting/crevice), is virtually immune to chloride-ionstress-corrosion cracking, and is highly resistant to oxidation. Among its many uses are aerospace applications, heat exchangers, nuclear-reactor components and power-plant flue-gas scrubbers. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-285. Producer or source: Jessop Steel Company.
