ASTM A – 92a() Standard Specification for Tool Steel High Speed
Unless otherwise specified, material shall be made by an electric melting process. A chemical analysis of each heat of steel shall be made to determine the percentage of the elements specified including carbon, manganese, phosphorus, sulfur, silicon, chromium, vanadium, tungsten, molybdenum, and cobalt and these values shall conform to the requirements as to the prescribed chemical composition.
Temper at F for a hardness of Rockwell C 60 to Cold working may be accomplished with the alloy in the annealed condition. The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given.
This abstract is a brief summary of the referenced standard. Do Not forge below F. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Selection will depend upon design, service conditions, a00 mechanical properties.
ASTM A600 – 92A(2016)
It may be shaped by grinding but is relatively poor in regard to capability of being ground. Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching in oil, air or astj bath.
The M2 alloy has somewhat better wear resistance than M1. Preheat at F before heating for hardening. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked xstm in Bar Products by 28 distributors but is also available to a lesser extent in Flat Rolled Products, Wire Products, and Shapes.
Forge at F down to F. Modulus of Astk Tension. Anneal at F and slow furnace cool at 40 F per hour, or less. Primarily used for cutting tools.

Hardens by heat treatment and quenching. See “Forging” and consult the supplier for information on working at lower temperatures. Two intermediate high speed tool steels designated as M50 and M52 are qstm covered. M2 is classified as a “medium” machinability tool steel in the annealed condition.
