A2 Tool Steel Hardness Before Hardening

A2 is intermediate in wear resistance between o1 oil hardening tool steel and d2 high carbon high chromium tool steel.

A2 tool steel hardness before hardening.

It s highly wear resistant and moderately tough. The carbon content in a2 tool steels is high. 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. It is heat treatable and will offer a hardness in the range 57 62 hrc.

A2 air hardening medium alloy cold work tool steels are a type of group a steels containing molybdenum and chromium. The steel is composted of 1 percent carbon 3 percent silicon 6 percent manganese 5 3 percent chromium 1 1 percent molybdenum and 2 percent vanadium. A2 tool steel is an air hardening cold work steel. A2 tool steel properties a2 is also an air hardening tool steel but includes less than half the chromium 4 75 5 50 and a bit less carbon 0 95 1 05 than d2.

Aisi a2 tool steel is high carbon high alloy tool steel designed to have excellent wear resistance and toughness. It is heat treatable and will offer a hardness in the range 57 62 hrc. The data below will provide an overview of a2 air hardening medium alloy cold work tool steels. Like d2 it is incredibly resistant to distortion during heat treating and is moderately machinable and grindable.

A2 steel is an air hardening cold work tool steel. A 5 chromium steel which provides high hardness after heat treatment with good dimensional stability. Generally supplied annealed to hb 231 max. The prefix a in the name designates it as an air hardening steel.

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. A2 is 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. Aisi a2 is an air hardening tool steel containing 5 pct chromium.

It replaces o1 when safer hardening better dimensional stability and increased wear resistance are required.
