Cold working may be accomplished with the alloy in the annealed condition. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Formed by machining or forging and then machining. Primarily used for cutting tools. Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching in oil, air or salt bath.

ASTM A – 92A() – Standard Specification for Tool Steel High Speed

Astn “Heat Treatment” and “Tempering”. Selection will depend upon design, service conditions, and mechanical properties. Hardens by heat treatment and quenching.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Anneal at F and slow furnace cool at 40 F per hour, or less.


Modulus of Elasticity Tension. Temper at F for a hardness of Rockwell C 60 to 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. Do Not forge below F.

The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given. It ast be shaped by grinding but is relatively poor in regard to capability of being ground.

See “Forging” and consult the supplier for information on working at lower temperatures. The M2 alloy has somewhat better wear resistance than M1. 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 primarily in Bar Products by 28 distributors but is also available to a lesser extent in Flat Rolled Products, Wire Products, and Shapes.

ASTM A600 Grade M42 cold-drawn

Historical Version s – view previous versions of standard. Consult the alloy supplier for information on the advisability of welding.

Unless otherwise specified, material shall be made by an electric melting process. This abstract is a brief summary of the referenced standard.

ASTM A600 Grade M1 annealed

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Preheat at F before heating for hardening. M2 is classified as a “medium” machinability tool steel in the annealed condition.

Two intermediate high speed tool steels designated as M50 and M52 are also covered. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Forge at F down to F. Not applicable to this alloy.
