ASTM A600 Grade M42 cold-drawn

Cold working may be accomplished with the alloy aatm the annealed condition. Forge at F down to F. Two intermediate high speed tool steels designated as M50 and M52 are also covered. 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.

Do Not forge below F. Hardens by heat treatment and quenching.

ASTM A, for Tool Steel High Speed – Otai Special Steel

The values qstm in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Temper at F for a hardness of Rockwell C 60 to Modulus of Elasticity Tension.

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 qstm the requirements as to the prescribed chemical composition.

Historical Version s – view previous versions of standard.

Unless otherwise specified, material shall be made by an electric melting process. Anneal at F and slow furnace cool at 40 F per hour, or less. Not applicable to this alloy. Formed by machining or forging and then machining.

Consult the alloy supplier for information on the advisability of welding. See “Forging” and consult the supplier for information on working at lower temperatures.

Primarily used for cutting tools.

See “Heat Treatment” and “Tempering”. It may be shaped by grinding but is relatively poor in regard to capability of being ground.

ASTM A600 – 92A(2016)

The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given. Link to Active This link will always route to the current Active version of the standard. M2 is classified as a “medium” machinability tool steel in the annealed condition.

Preheat at F before heating for hardening. The M2 alloy has somewhat better wear resistance than M1.
