Standard Specification for Wrought Seamless or Welded and Drawn 18 Chromium-14Nickel-2.5Molybdenum Stainless Steel Small Diameter Tubing for Surgical Implants (UNS S31673)
 N F2257

Annotation

This specification covers the requirements for wrought 18chromium-14nickel-2.5molybdenum stainless steel tubing used for the manufacture of surgical implants. Material shall conform to the applicable requirements of Specification F 138 (for seamless) or Specification F 139 (for welded and drawn). This specification addresses those product variables that differentiate small-diameter medical grade tubing from the bar, wire, sheet, and strip product forms covered in these specifications.

This specification applies to cold finished straight length tubing with 3 mm (0.125 in.) and smaller nominal outside diameter (OD) and 0.5 mm (0.020 in.) and thinner nominal wall thickness.

The specifications in 2.1 are referred to as the ASTM material standard(s) in this specification.

The values stated in either inch-pound or SI units are to be regarded separately as standard. Inch-pound units are shown in parentheses. 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.

*A Summary of Changes section appears at the end of this standard.
