ASTM A954-96

Standard Specification for Austenitic Chromium-Nickel-Silicon Alloy Steel Seamless and Welded Pipe

SCOPE
1.1 This specification covers seamless and straight-seam welded austenitic steel pipe intended for high-temperature and general corrosive service, having a specified minimum chromium content of less than 10.50%.  
1.2 Appendix X1 lists the dimensions of welded and seamless stainless steel pipe as shown in ANSI B36.19. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.  
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. Unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished in inch-pound units.
