It may be shaped by grinding but is relatively poor in regard to capability of being ground.
ASTM A600 Grade M1 annealed
Not applicable to this alloy. Link to Active This link will always route to the a6600 Active version of the standard. 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 x600 and application.
Unless otherwise specified, material shall be made by an electric melting process. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Forge at F down to F. This abstract is a brief summary of the referenced standard. Anneal at F and slow furnace cool at 40 F per hour, or less. Formed by machining or forging and then x600. Preheat at F before heating for hardening. M2 is classified as a “medium” machinability tool steel 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. Selection will depend upon design, service conditions, astk mechanical properties. Modulus of Elasticity Tension. Hardens by heat treatment and quenching.
Primarily used for cutting tools. See “Forging” and consult the supplier for information on working at lower temperatures.
Consult the alloy supplier for information on the advisability of welding. 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 M42 cold-drawn
Temper at F for a hardness of Rockwell C 60 to The M2 alloy has somewhat better wear resistance awtm M1. See “Heat Treatment” and “Tempering”.
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. The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given.
Distributors will offer small quantity buys while mills a60 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.
Historical Version s – view previous versions of standard.
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. Do Not forge below F. Cold working may be accomplished with the alloy in the annealed condition. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
