Chemical Composition (%)

Cold Work Tool Steel AISI A2 is a versatile, air-hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment. A2 is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel. A2 provides an effective combination of strength and toughness, tool performance, price, and a wide variety of product forms.

Good machinability

High stability after hardening

High compressive strength

Good hardenability

Good wear resistance.
