The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given.

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

Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching in oil, air or salt bath. Selection will depend upon design, service conditions, and mechanical properties.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This abstract is a brief summary of the referenced standard. Unless otherwise specified, material shall be made by an electric melting process.

Historical Version s – view previous versions of standard. 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.

Forge at F down to F. M2 is classified as a “medium” machinability tool steel astj the annealed condition. Modulus of Elasticity Tension. See “Heat Treatment” and “Tempering”.

Two intermediate high speed tool steels designated as M50 and M52 are also covered. Consult the alloy supplier for information on the advisability of welding. Formed by machining or forging and then machining.

Link to Active This link will always route to the current Active version of the standard. Primarily used for asrm tools. Hardens by heat treatment and quenching.

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 aa600 conform to the requirements as to the prescribed chemical composition.

Temper at F for a hardness of Rockwell C 60 to It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for x600 use and application. It may be shaped by grinding but is relatively poor in regard to capability of being ground.


ASTM A600, Tool Steel High Speed

See “Forging” and consult the supplier for information on working at lower temperatures. 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 a060 not provided as part of the standard. Not applicable to this alloy.

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

Anneal at F and slow furnace cool at 40 F per hour, or less. Do Not forge below F.
