D5 is a high-carbon high-chromium cold work steel that exhibits high resistance to softening at temperatures. This datasheet provides information on composition, physical properties, and hardness. It also includes information on heat treating and machining. Filing Code: TS-532. Producer or source: Tool steel mills.

COBALT CHROME is an air-hardening,high-carbon, high-chromium die steel. The addition of approximately 3% to this steel gives it extra resistance to galling and pick-up and additional red hardness which is useful on semi-hot-work applications. It also is recommended when it is desirable to nitride specialized tools. Its many uses include dies, gages, punches, rolls and slitter knives. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-427. Producer or source: Latrobe Steel Corporation.

AL Tech D-5 is a high-carbon, high-chromium tool and die steel; it contains cobalt (3.30%) and is air-hardening and nondeforming. The cobalt impacts a pronounced secondary hardening effect in tempering and a non-galling effect. AL Tech D-5 has both superior abrasion resistance and greater edge strength than ordinary high-carbon, high-chromium die steels. It is used for many types of dies, hot-piercing punches and shear blades. This datasheet provides information on composition, physical properties, and hardness as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-372. Producer or source: AL Tech Specialty Steel Corporation.

AL TECH CHEROKEE is a high-carbon, high-chromium die steel containing nominally 3.25% cobalt. The cobalt provides effective resistance to galling and pickup as well as improved hot hardness. The cobalt enables this steel to perform exceptionally well on both extended cold-work and moderate hot-work applications. Another feature of this versatile die steel is its outstanding secondary hardness associated with remarkable tempering resistance up to 900 F. Typical applications comprise blanking dies, swaging dies, hot and cold-piercing punches, forming rolls, shear blades and coining dies. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-465. Producer or source: AL Tech Specialty Steel Corporation.
