ASTM A789/A789M-09
Historical Standard: ASTM A789/A789M-09 Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service
SUPERSEDED (see Active link, below)
ASTM A789 / A789M
1. Scope
1.1 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.
1.2 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. 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.
