1: A2 steel introduction
AISI A2 tool steel is one of 'A' group cold works steel in ASTM A681 standard. A2 Tool Steel is a versatile, air hardening chromium alloy tool steel that replaces O1 tool steel when safer hardening, less distortion and increased wear resistance are required. AISI type A2 steel is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel.
AISI Steel A2 is heat treatable and will offer a hardness in the range 57-62 HRC. ASTM grade A2 steel delivers good toughness with medium wear resistance and is relatively easy to machine. Tool Steels A2 are used in many applications which require good wear resistance as well as good toughness.

4: A2 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
