Consult the alloy supplier for information on the advisability of welding.
It may be shaped by grinding but is relatively poor in regard to capability of being ground. Do Not forge below F. Cold working may be accomplished with the alloy in the annealed condition.
M2 is classified as a “medium” machinability tool atm in the annealed condition.
ASTM A Standard Specification for High Speed Tool Steel
Two intermediate high speed tool steels designated as M50 and M52 are also covered. Not applicable to this alloy.
Unless aastm specified, material shall be made by an electric melting process. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Preheat at F before heating for hardening. Forge at F down to F. The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given. Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching in oil, air or salt bath.
ASTM A600 Grade M1 annealed
Distributors will offer small quantity buys while mills will generally only sell large quantities, ast, 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.
Selection will depend upon design, service conditions, and mechanical properties.
Formed by machining or forging and then machining. Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. Hardens by heat treatment and quenching. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but awtm not provided as part of the standard. See “Forging” and consult the supplier for information on working at lower temperatures. See “Heat Treatment” and “Tempering”.
Primarily used for cutting tools.
The M2 alloy has somewhat better wear resistance than M1. 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 a60 to the prescribed chemical composition.
