What is ASTM A789 Steel Pipe?

Duplex Stainless Steel Pipe has a structure that contains both ferrite and austenite. Duplex alloys have higher strength and better stress corrosion cracking resistance than most austenitic alloys and greater toughness than ferritic alloys, especially at low temperatures. The corrosion resistance of duplex alloys depends primarily on their composition, especially the amount of chromium, molybdenum, and nitrogen they contain.

ASTM A789/ ASME SA789 steel pipe covers seamless and welded ferritic/austenitic stainless steel tubing for general services. The standard is also applied to duplex stainless steel tube material. All tubes in this standard shall be furnished with heat-treated conditions according to specified temperature and quench conditions. When the final heat treatment is in a continuous furnace, or when heat-treated condition is obtained directly by quenching after hot forming, the number of tubes of the same size and from the same heat lot shall be determined from the prescribed sizes of the tubes.
