HAMPDEN is an oil-hardening, high-carbon, high-chromium die steel with excellent wear resistance. It hardens with very little change in size or shape. It has very high compressive strength and mild resistance to corrosion because of its high chromium content. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-299. Producer or source: Carpenter.
