Deutsche Edelstahlwerke Cryodur 1730 is a medium-carbon, non-alloy cold-work tool steel. It is primarily used in the non-heattreated condition. For special applications it is used in the quenched and tempered condition. Owing to its low hardenability Cryodur 1730 develops a fully hardened zone that is relatively thin, even when quenched drastically. Thicker sections have a hard case over a tough core. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on wear resistance as well as heat treating, machining, and joining.
