Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Dimensions and Permissible Variations The following three alloys are included: If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

These special combinations of properties such as increased ductility, electrical conductivity, dimensional accuracy, endurance life, and resistance to elastic drift and hysteresis in springs, may be obtained by special precipitation-hardening heat treatments.

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. 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 5 distributors but is also available to a lesser extent in Wire Products, and Flat Rolled Products.
