    Duplex Stainless Steel Pipe ASTM A790/A928/A789 S31803 S32750 S32760 S31254 254Mo


    Duplex Stainless Steel have 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.

    Standard: ASTM/ASME A/SA789, A/SA790, A/SA928, DIN17456/17458, EN10216-5. After negotiation, we can supply pipe with customer's special requirement.
