ATLAS 316, ATLAS 316L, ATLAS 316H

Abstract

Atlas 316 is a chromium-nickel-molybdenum austenitic stainless steel, second only to Atlas 304 in commercial importance. The molybdenum gives Atlas 316 better overall corrosion resistant properties than type 304 austenitic stainless steel, particularly higher resistance to pitting and crevice corrosion in chloride environments. It is readily brake or roll formed, welded, soldered, and cut by both thermal and mechanical methods. The austenitic structure gives excellent toughness, even down to cryogenic temperatures. Atlas 316L, the low carbon version of Atlas 316, is highly resistant to sensitization (grain boundary carbide precipitation) and so is extensively used in heavy gauge welded components; about 5 mm, 0.2 in., and over. Atlas 316H, with its higher carbon content, has some application at elevated temperatures, as does stabilized type 316Ti. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as heat treating, machining, and joining. Filing Code: SS-1365. Producer or source: Atlas Steels.
