A2 Tool Steel Hardness Before Hardening

It is heat treatable and will offer a hardness in the range 57 62 hrc.

A2 tool steel hardness before hardening.

Aisi a2 is an air hardening tool steel containing 5 pct chromium. A2 is intermediate in wear resistance between o1 oil hardening tool steel and d2 high carbon high chromium tool steel. A2 air hardening medium alloy cold work tool steels are a type of group a steels containing molybdenum and chromium. A2 tool steel is an air hardening cold work steel.

A 5 chromium steel which provides high hardness after heat treatment with good dimensional stability. A2 tool steels can be deep hardened in order to minimize distortion. It s highly wear resistant and moderately tough. A2 provides an effective combination of strength and toughness tool performance price and a wide variety of product forms.

A2 is a 5 chromium steel which provides high hardness after heat treatment with good dimensional stability. Generally supplied annealed to hb 231 max. A2 tool steel is a versatile air hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment. The carbon content in a2 tool steels is high.

It is heat treatable and will offer a hardness in the range 57 62 hrc. A simplified guide to heat treating tool steels when we consider that the greater overall costs of most tools and dies are incurred prior to heat treatment and further that proper heat treatment is critical to the successful application of tooling this so called hardening process is placed. The prefix a in the name designates it as an air hardening steel. A2 steel is an air hardening cold work tool steel.

The data below will provide an overview of a2 air hardening medium alloy cold work tool steels. Use for dies punches and similar forming and blanking tools as recommended for type o1 but where less distortion in heat treatment or better wear resistance is required. Like d2 it is incredibly resistant to distortion during heat treating and is moderately machinable and grindable. A2 tool steel is a 5 chromium medium alloy cold work tool steel possessing sufficient hardenability to be air hardened to 60 rc surface hardness level with good depth of hardening.

Aisi a2 tool steel is high carbon high alloy tool steel designed to have excellent wear resistance and toughness.
