    This specification covers the requirements for wrought seamless or welded and drawn 18chromium-14nickel-2.5molybdenum stainless steel small diameter tubing for surgical implants. Manufacturing method shall be seamless or welded and drawn process. Tubing shall conform to chemical composition, dimensions, and mechanical properties of this specification. Mechanical properties include ultimate tensile strength, yield strength, and elongation. Outside and inside diameter, wall thickness, length and straightness shall conform to the permissible limits of this specification.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 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 F138 (for seamless) or Specification F139 (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.

    1.2 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.

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

    1.4 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.
