ASTM A681 - 08

ASTM A681
Abstract

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.

This abstract is a brief summary of the referenced 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 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.

1. Scope

 

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.

 

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the Standard.
