This specification covers the chemical, mechanical, and metallurgical requirements for wrought nitrogen strengthened 22chromium-13nickel-5manganese-2.5molybdenum stainless steel alloy bar and wire for surgical implants (UNS S20910). Materials shall be tested and shall conform to chemical requirements such as chemical composition, and product analysis; metallurgical requirements such as inclusion; and mechanical requirements such as dimension, tensile strength, yield strength, elongation, and Brinell hardness.

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.
