Standard Guide for Specifying Harmonized Standard Grade Compositions for Wrought Stainless Steels

Importancia y uso:

4.1 It is anticipated that the ASTM Subcommittees A01.06, A01.10, A01.17, A01.22, and A01.28 will use the standard composition limits listed in this guide for the grades identified by the corresponding UNS designation in the product specification unless there is a specific technical justification for doing otherwise. The compositions in this guide shall not be considered as chemical requirements for any particular product until adopted by the subcommittee overseeing that product.

4.2 Assuming that uniform compositions among the many product standards for stainless steel are desirable, the composition limits provided in this standard are to be used as guides in determining limits for each of the elements included in the total composition of each grade. The composition limits have been established with the intent that each product subcommittee will find it necessary to require only a minimum number of changes to reflect specific technical effects. Section 5 lists the general guidelines followed for determining the limits for each element; the limits established in this guide are based on these guidelines.

4.3 Not included in this standard stainless steel grade harmonization effort is an attempt to unify stainless steel compositions in ASTM product standards by any means other than recognizing current industry practices.
