A2 Tool Steel Properties

A2 steel contains 5 of chromium steel which provides high hardness after heat treatment with good dimensional stability.
A2 tool steel properties. A2 tool steel properties. The carbon content in a2 tool steels is high. This widely used tool steel has low distortion in heat treatment good machinability good toughness for severe service high abrasion resistance and deep. 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.
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. A 2 tool steel high vanadium steel aisi a2 tool steel is an air hardening grade of steel that contains 5 chromium. The data below will provide an overview of a2 air hardening medium alloy cold work tool steels. Tool steel refers to a variety of carbon and alloy steels that are particularly well suited to be made into tools.
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. Aisi a2 tool steel is one of a group cold works steel in astm a681 standard. These characteristics make it a versatile tool steel that combines good performance and price. S7 tool steel is a versatile formulation suitable for both cold and hot work service.
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. A2 tool steels can be deep hardened in order to minimize distortion. S7 tool steel properties.
It is heat treatable and will offer a hardness in the range 57 62 hrc. The chemical composition of a2 tool steels is outlined in the following table. Aisi type a2 steel is intermediate in wear resistance between o1. A2 tool steel is an air hardening cold work steel of group a steels containing molybdenum and chromium.
The first high speed steel came to be known as t1 which had 4 cr and 18 w tungsten. A2 tool steel is an air hardening cold work steel. A2 is noted for its good toughness and excellent dimensional stability in heat treatment.
