Outside of the us it is commonly known as a2 stainless steel in accordance with iso 3506 not to be confused with a2 tool steel.

Sae tool steel grades.

The aisi sae general purpose grades of tool steel are o 1 a 2 and d 2. The sae steel grades system is a standard alloy numbering system for steel grades maintained by sae international. These are four digit numbers which represent chemical composition standards for steel specifications. Table of steel equivalent grades en sae aisi uns din bs uni jis the table below compares steel equivalent grades of materials from various international specifications.

The aisi sae grades of tool steel is the most common scale used to identify various grades of tool steel. Steel and steel is introduced including chemical composition and mechanical performance data each steel grade property. Ss 2260 united kingdom. These efforts were similar and overlapped significantly.

Events events our major market leading conferences and events offer optimum networking opportunities to all participants while adding great value to their business. The second digit indicates there are no alloying elements. Air hardening medium alloy cold work steel.

Type 304l same as the 304 grade but lower carbon content to increase weldability. Individual alloys within a grade are given a number. These standard grade steels are considered cold working steels that can hold their cutting edge at temperatures up to about 400 c. The last two digits indicates that the steel contains approximately 0 20 percent carbon.

For several decades the systems were united into a joint system designated the aisi sae steel grades. They exhibit good hardness abrasion resistance and deformation resistance. Jis skd 12 sweden. Note that materials compared are the nearest available grade and may have slight variations in actual chemistry.

The system is based on the chemical compositions of the steels and alloys. Type 304 the most common grade.
