A2 Tool Steel Heat Treat

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

A2 tool steel heat treat.

Like d2 it is incredibly resistant to distortion during heat treating and is moderately machinable and grindable. A2 tool steel a2 tool steel is a versatile air hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment. By james croxon a2 tool steel can be difficult to heat treat. Heat treatment a2 tool steels are heated slowly to 788 c 1450 f and this is followed by increasing the temperature to 954 c 1750 f.

A2 tool steel is an air hardening cold work chromium alloy die steel that is preferable to o1 tool steel in applications requiring greater size stability machinability and safer hardening. The wear resistance properties and cost place a2 between that of o1 and d2 tool steel making it a good all purpose grade for many applications. 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. A2 is intermediate in wear resistance between o1 oil hardening tool steel and d2 high carbon high chromium tool steel.

These steels must be heat treated to develop their characteristic properties. A2 steel is an air hardening cold work tool steel. It is heat treatable and will offer a hardness in the range 57 62 hrc. In this condition most of the alloy content exists as alloy carbides dispersed throughout a soft matrix.

A 5 chromium steel which provides high hardness after heat treatment with good dimensional stability. 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. It s highly wear resistant and moderately tough. A2 has a fully spheroidized structure and has exceptionally low inclusion levels.

This widely used tool steel has low distortion in heat treatment good machinability good toughness for severe service high abrasion resistance and deep hardening properties in large sections.
