See “Forging” and consult the supplier for information on working at lower temperatures. This abstract is a brief summary of the referenced standard. Modulus of Elasticity Tension.

The M2 alloy has somewhat better wear resistance than M1. Hardens by heat treatment and quenching.

ASTM A600 – 92A(2016)

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


Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Not applicable to this alloy.

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

Forge at F down to F. Consult the alloy supplier for information on the advisability of welding. M2 is classified as a “medium” machinability tool steel in the annealed condition.

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.

Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching awtm oil, air or salt bath. Historical Version s – view previous versions of standard. Temper at F for a hardness of Rockwell C 60 to Unless otherwise specified, material shall be made by an electric melting process.

The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given. Anneal at F and slow furnace cool at qstm F per hour, or less. 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.


ASTM A600 1992 Standard Specification for High Speed Tool Steel

See “Heat Treatment” and “Tempering”. Primarily used for cutting tools.

Formed by machining or forging and then machining. 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.

Preheat at F before 6a00 for hardening. Link to Active This link will always route to the current Active version of the standard. Two intermediate high speed tool steels designated as M50 and M52 are also covered. It a60 be shaped by grinding but is relatively poor in regard to capability of being ground.

Do Not forge below F.
