Consult the alloy supplier for information on the advisability of welding. Do Not forge below F. Unless otherwise specified, material shall be made by an electric melting process. 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.
ASTM A600 Grade M42 cold-drawn
Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching in oil, air or salt bath. The M2 alloy has somewhat aa600 wear resistance than M1.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This abstract is xstm brief summary of the referenced standard. Temper at F for a hardness of Rockwell C 60 to It may be shaped by grinding but is relatively poor in regard to capability of being ground.
ASTM A – 92a() Standard Specification for Tool Steel High Speed
Hardens by heat treatment and quenching. Preheat at F before heating for hardening. 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 asgm Flat Rolled Products, Wire Products, and Shapes.
M2 is classified as a “medium” machinability tool steel in the annealed condition.
Selection will depend upon design, service conditions, and mechanical properties. Not applicable to this alloy. Primarily used for cutting tools.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. A chemical analysis of each heat of steel shall be made to determine the asmt 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.
Cold working may be accomplished with the alloy in asym annealed condition.
Historical Version s – view previous versions of standard. ASTM does not give any warranty express or implied or make asrm representation that the contents of this abstract are accurate, complete or up to date. Two intermediate high speed tool steels designated as M50 and M52 are also covered. Forge at F down to F. Modulus of Elasticity Tension. Link to Active This link will always route to the current Active version of the standard. The maximum Brinell hardness and minimum Rockwell C aatm for the tool steels are given.
See “Forging” and consult the supplier for information on working at lower temperatures. Formed by machining or forging and then machining.
Anneal at F and slow furnace cool at 40 F per hour, or less. See “Heat Treatment” and “Tempering”.
