    1. Scope

    This specification covers grades of nominal wall thickness, stainless steel tubing for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.

    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. Within the text, the SI units are shown in brackets. The inch-pound units shall apply unless the M designation of this specification is specified in the order.

    Keywords:Corrosive Service Applications - Duplex And Super Duplex Stainless Steel - Seamless Pipes And Tubes - Stress Corrosion Cracking - Welded Pipes And Tubes
    Size Range: OD: 6-89mm, WT: 1-8mm, Length: 5.8m/6m, maximal 11.8m
