Abstract

BETHADUR 420 (AISI Type 420) is a 12.00 to 14.00% chromium stainless mold steel for plastics. Its good resistance to corrosion plus its working hardness level of Rockwell C 52 contribute to low maintenance costs for molds. 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, and machining. Filing Code: SS-355. Producer or source: Bethlehem Steel Corporation.
