ATMODIE is a high-carbon, high-chromium, air-hardening tool steel. It has a unique combination of hardness, toughness and non-deforming qualities. Its hardenability is high enough to develop full hardness through large sections; this makes it outstanding as the heavy-duty die and cold-forming tool steel, excellent for blanking heavy sheet and plate. ATMODIE is particularly useful for long-run tools and dies requiring close dimensional accuracy in hardening. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-470. Producer or source: Columbia Tool Steel Company.
