w600 Forge at F down to F. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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. Temper at F for a hardness of Rockwell C 60 to Selection will depend upon design, service conditions, and mechanical properties.
Two intermediate high speed tool steels designated as M50 and M52 are also covered. Modulus of Aetm Tension. Historical Version s – view previous versions of standard.
ASTM A600 Grade M42 cold-drawn
Then adtm rapidly from F to F and hold for 3 to 5 minutes followed by quenching in oil, air or salt bath. Not applicable to this alloy. Do Not forge below F. Unless otherwise specified, material shall be made by an electric melting process. The maximum Brinell hardness and minimum Sstm C hardness for the tool steels are given.
See “Forging” and consult the supplier for information on working at lower temperatures.
ASTM A – 92A() – Standard Specification for Tool Steel High Speed
Cold working may be accomplished with the alloy in the annealed condition. Hardens by heat treatment and quenching.
Preheat at F before heating for hardening. Formed by machining or forging and then machining. Consult the alloy supplier for information on the advisability of welding. Link to Active This link will always route to the current Active version of the standard.
This abstract is a brief summary of the referenced standard.
Grades and Trade Names
A chemical analysis of each heat of steel shall be made to determine the percentage of the elements specified including carbon, manganese, asttm, sulfur, silicon, chromium, vanadium, tungsten, molybdenum, and cobalt and these values shall conform to the requirements as to the prescribed chemical composition.
The M2 alloy has somewhat better wear resistance than M1. It may be shaped by grinding but is relatively poor in regard to capability of being ground. See “Heat Treatment” and “Tempering”.
Anneal at F and slow furnace cool at 40 F per hour, or less. It is informational only and not an astn part of the standard; the full text of the standard itself must be referred to for its use and application. M2 is classified as a “medium” machinability tool steel in the annealed condition.
