Deutsche Edelstahlwerke Cryodur 2002 is a high-carbon, alloy cold-work tool steel in which the principal alloying element is chromium. It is among the least expensive of the tool steels and requires strict control of processing and heat treatment to achieve good properties and performance. The low alloy content of this steel yields few alloy carbides and, therefore, lower wear resistance compared to the more highly alloyed tool steels. The hardenability of Cryodur 2002 is low, and rapid quenching is required to produce a martensitic microstructure. Despite rapid quenching, this steel may harden only to shallow depths. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming and heat treating. Filing Code: TS-809.

WATERDIE EXTRA is a high-quality water-hardening tool steel alloyed with chromium to give increased depth of hardened case with added resistance to abrasion. When quenched in water or brine, it develops a deep, uniform high-hardness case with a tough shock-dampening core. This steel gives outstanding performance in large-section tools and dies that demand the strength of an extra-deep hardened case backed by a tough core. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-477.
