AISI A8 MOD Forged Cold Work Tool Steel
1: AISI A8 MOD steel introduction
This steel is an improved steel of A8 steel, with good hardenability, toughness, heat treatment dimensional stability. Suitable for punches and cold forging dies with hardness requirements of 55-60 HRC. In addition, it is suitable for manufacturing non-metallic materials due to good hardness, wear resistance and toughness.
