A2 tool steel properties.

A 2 tool steel high vanadium steel aisi a2 tool steel is an air hardening grade of steel that contains 5 chromium. S7 tool steel is a versatile formulation suitable for both cold and hot work service. A2 is noted for its good toughness and excellent dimensional stability in heat treatment. Aisi type a2 steel is intermediate in wear resistance between o1.

Aisi a2 tool steel is one of a group cold works steel in astm a681 standard. The carbon content in a2 tool steels is high. 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. A2 tool steels can be deep hardened in order to minimize distortion.

A2 steel contains 5 of chromium steel which provides high hardness after heat treatment with good dimensional stability. A2 tool steel is an air hardening cold work steel of group a steels containing molybdenum and chromium. This widely used tool steel has low distortion in heat treatment good machinability good toughness for severe service high abrasion resistance and deep. The first high speed steel came to be known as t1 which had 4 cr and 18 w tungsten.

Tool steel refers to a variety of carbon and alloy steels that are particularly well suited to be made into tools. It is heat treatable and will offer a hardness in the range 57 62 hrc. 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. 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.

The chemical composition of a2 tool steels is outlined in the following table. It has a relatively low carbon concentration compared to d2 and a2 steels 0 45 0 55 and significantly less chromium 3 00 3 50. S7 tool steel properties. These characteristics make it a versatile tool steel that combines good performance and price.

A2 tool steel is an air hardening cold work steel. 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 a 5 chromium steel which provides high hardness after heat treatment with good dimensional stability.
