JESSOP JS800/800H is an austenitic stainless steel with good resistance to corrosion and oxidation at elevated temperatures; 800 and 800H are identical in composition except that 800H contains a higher specified level of carbon than 800. This steel also shows fair resistance to stress-corrosion cracking. It has good strength and impact properties over a wide range of temperatures. JS800H also exhibits very good creep strength up to at least 1500 F. Uses include the chemical process industry and equipment of heat treating. 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: SS-448. Producer or source: Jessop Steel Company.
