Die Steel 1566 is a high-carbon, high-manganese tool steel that combines strength, hardness, and elasticity. Its high hardenability enables exceptional wear resistance and fatigue strength after heat treatment, making it suitable for mechanical components subjected to high loads, repeated impacts, or requiring high elasticity.
