ASTM A600 Grade M42 cold-drawn

Unless astj specified, material shall be made by an electric melting process. Anneal at F and slow furnace cool at 40 F per hour, or less. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Primarily used for cutting tools.

A chemical analysis of each heat of steel sstm 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. Not applicable to this alloy. Preheat at F before heating for hardening.

Grades and Trade Names

The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given. Cold a60 may be accomplished with the alloy in the annealed condition. The M2 alloy has somewhat better wear resistance than M1. Modulus of Elasticity Tension.

Selection will depend upon design, service conditions, and mechanical properties. 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 a60 but is also available to a lesser extent in Flat Rolled Products, Wire Products, and Shapes. The values given in parentheses are a6000 conversions to SI units that are provided for information only and are not considered standard.

Do Not forge below F. Forge at F down to F.

ASTM A T5 High Speed Tool Steel Round Bar

Formed by machining or forging and then machining. Then heat rapidly from F to F and hold for 3 to 5 minutes followed by quenching in oil, air or salt bath. See “Forging” and consult the supplier for information on working at lower temperatures. See “Heat Treatment” and “Tempering”.


ASTM A600, Tool Steel High Speed

Two intermediate high speed tool steels designated as M50 and M52 are also covered. M2 is classified as a “medium” machinability tool steel in the annealed condition. 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 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. Hardens by heat treatment and quenching.

It may be shaped by grinding but is relatively poor in regard to capability of being ground. This abstract is a brief summary of the referenced standard. Historical Version s – view previous versions of standard.

Temper at F for a hardness of Rockwell C 60 to
