Sae Tool Steel Grades

Steel and steel is introduced including chemical composition and mechanical performance data each steel grade property.

Sae tool steel grades.

Alloy steels and carbon steels can be designated with specific grades by a four digit aise sae numerical index system. They exhibit good hardness abrasion resistance and deformation resistance. The first digit indicates that this is plain carbon steel. The classic 18 8 stainless steel.

Type 304l same as the 304 grade but lower carbon content to increase weldability. Note that materials compared are the nearest available grade and may have slight variations in actual chemistry.

These are four digit numbers which represent chemical composition standards for steel specifications. The aisi sae grades of tool steel is the most common scale used to identify various grades of tool steel. Individual alloys within a grade are given a number. The system is based on the chemical compositions of the steels and alloys.

Events events our major market leading conferences and events offer optimum networking opportunities to all participants while adding great value to their business. In the 1930s and 1940s the american iron and steel institute and sae were both involved in efforts to standardize such a numbering system for steels.

Individual alloys within a grade are given a number. The society of automotive engineers sae designates sae steel grades. These standard grade steels are considered cold working steels that can hold their cutting edge at temperatures up to about 400 c. The sae steel grades system is a standard alloy numbering system for steel grades maintained by sae international.

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. For several decades the systems were united into a joint system designated the aisi sae steel grades. Type 304 the most common grade. The second digit indicates there are no alloying elements.
