Tool Grade
A2 Steel
Cold work
Medium-alloy, air-hardening tool steel known for its balance of toughness, wear resistance and dimensional stability. Used to make dies, punches, knives and tooling for cutting, forming and cold work. Its air hardening reduces the risk of distortion and cracking during heat treatment, delivering reliable performance in medium-volume production applications.
Main features
Air hardening with minimal distortion
