This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products. The material shall be made by an electric melting process. It shall be made from ingots that have been reduced in cross section in such a manner and to such a degree as to ensure proper refinement of the ingot structure. Chemical composition, hardness, macrostructure and decarburization of the material shall conform to the requirements in accordance to the referenced ASTM documents itemized herein.
1.1 This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products.
1.2 These products, which include hot or cold finished bar, plate, sheet, strip, rod, wire, or forgings, are normally fabricated into tools, dies, or fixtures. The selection of a material for a particular application will depend upon design, service conditions, and desired properties.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
