3、pe*1.1 This specification covers austenitic austenitic, austenitic-ferritic, and age-hardenable stainless steel round spring wireintended especially for the manufacture of springs.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values state

4、d in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.2
