A2 Tool Steel Properties

Aisi type a2 steel is intermediate in wear resistance between o1.

A2 tool steel properties.

The first high speed steel came to be known as t1 which had 4 cr and 18 w tungsten. 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 one of a group cold works steel in astm a681 standard. A2 tool steel is a versatile air hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment a2 is intermediate in wear resistance between o1 oil hardening tool steel and d2 high carbon high chromium tool steel.

A2 tool steel is an air hardening cold work steel. A2 is a 5 chromium steel which provides high hardness after heat treatment with good dimensional stability. A 2 tool steel high vanadium steel aisi a2 tool steel is an air hardening grade of steel that contains 5 chromium. 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.

It is heat treatable and will offer a hardness in the range 57 62 hrc. This widely used tool steel has low distortion in heat treatment good machinability good toughness for severe service high abrasion resistance and deep. S7 tool steel is a versatile formulation suitable for both cold and hot work service. These characteristics make it a versatile tool steel that combines good performance and price.

The data below will provide an overview of a2 air hardening medium alloy cold work tool steels. The earliest record i have found of a precursor a2 type steel is in a summary of tool steels in 1925 1 while summaries of tool steels from 1910 2 and 1915 3 do not have any similar steels. 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. The chemical composition of a2 tool steels is outlined in the following table.

A2 steel contains 5 of chromium steel which provides high hardness after heat treatment with good dimensional stability. A2 is noted for its good toughness and excellent dimensional stability in heat treatment. Tool steel refers to a variety of carbon and alloy steels that are particularly well suited to be made into tools. 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 carbon content in a2 tool steels is high. S7 tool steel properties. A2 tool steel properties.
