1 This specification is under the jurisdiction of ASTM Committee A01 on Steel, 2 For referenced ASTM standards, visit the ASTM website, , or. ASTM Aa(). Standard Specification for Tool Steel High Speed. standard by ASTM International, 03/01/ View all product details. Most Recent. ASTM A Standard Specification for High Speed Tool Steel.
Not applicable to this alloy. M2 is classified as a “medium” machinability tool steel in the annealed condition. Forge at F down to F.
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 aatm. Cold working may be accomplished with the alloy in the annealed condition.
This abstract is a brief summary of the referenced standard. Modulus of Elasticity Tension.
ASTM A T5 High Speed Tool Steel Round Bar
See “Heat Treatment” and “Tempering”. Formed by machining or forging and then machining. Anneal at F and slow furnace cool at 40 F per hour, or less. Historical Version s – view previous versions of standard. Do Not forge below F. 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 values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Primarily used for cutting tools. Preheat at F before heating for hardening.
The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Link to Active This link will always route to the current Active version of the 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 Ast, Wire Products, and Shapes.
ASTM A600 1992 Standard Specification for High Speed Tool Steel
Two intermediate high speed tool steels designated as M50 and M52 are also covered. It may be shaped by grinding but is relatively poor in regard to capability of being ground. Selection will depend upon design, service conditions, and mechanical properties. 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.
Unless otherwise asstm, material shall be made by an electric melting process. The M2 alloy has somewhat better wear resistance than M1. Temper at F for a hardness of Rockwell C 60 to See “Forging” and consult the supplier for information on working at lower temperatures.
Hardens by heat treatment and quenching. Consult the alloy supplier for information on the advisability of welding.
