Tool Steel Grades

Tool steel grades possess such mechanical properties that enable them to undergo various machining conditions.

Variety of tool steel

Tool steel grades are mainly used for cutting and machining other types of steel and are always used in heat treated applications.

Tool steels, like all other types of steel and alloys, also have varied grades suited for any type of uses specifically for machining and cutting since they possess such hard strength and toughness.

Specifically, tools steel has a variety of tool steel groups which include oil hardening, shock resisting, water hardening, air hardening, cold working, hot working, mold steel, high speed, and special purpose tool steel.​​
Advance Grinding Services has set the following tool steel grades that have different properties intended for specific uses.
