Standard Specification for Wrought Nitrogen Strengthened 22 Chromium–13 Nickel–5 Manganese–2.5 Molybdenum Stainless Steel Alloy Bar and Wire for Surgical Implants (UNS S20910)

SCOPE
1.1 This specification covers the chemical, mechanical, and metallurgical requirements for wrought nitrogen strengthened 22 chromium – 13 nickel – 5 manganese – 2.5 molybdenum stainless steel alloy bar and wire for surgical implants.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
