M2 is classified as a “medium” machinability tool steel in the annealed condition. Modulus of Elasticity Tension. Temper at F for a hardness of Rockwell C 60 to Unless otherwise specified, material shall be made by an electric melting process.

Not applicable to this alloy. Anneal at F and slow furnace cool at 40 F per hour, or less. 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, ast, cobalt and these values shall conform to the requirements as to the prescribed chemical composition.

Link to Active This link will always route to the current Active version of the standard. Forge at F down to F. Consult the alloy supplier for information on the advisability of welding. See “Forging” and consult the supplier for information on atsm at lower temperatures. The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given.

Hardens by heat treatment and quenching. The M2 alloy has somewhat better wear resistance than M1. Historical Version a6000 – view previous versions of standard. Two intermediate high speed tool steels designated as M50 and M52 are also covered.

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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Selection will depend upon design, service conditions, and mechanical properties. 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.

Cold working may be accomplished with the alloy in the annealed condition.

Primarily used for cutting tools. Formed by machining or forging and then machining.

It may be shaped by grinding but is relatively poor in regard to capability of being ground. Preheat at F before heating for hardening.

This abstract is a brief summary of the referenced standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Do Not forge below F.

Distributors will offer small quantity buys while aetm 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.

See “Heat Treatment” and “Tempering”. Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching aastm oil, air or salt bath.
