Duplex Ferritic Austenitic Stainless Steel Tube Pipe - Chinaprice: contact company for price
Duplex Stainless Steels 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.

- Business Description: Since LSI s first successful supplying of such great material for China Steel Corporation, LSI has completed more than 500 Kilometers S30815 (Alloy 253MA,EN1.4825) tubes and pipes for domestic and overseas customers and got 100% satisfaction with 0 complaints from customers and end users till today. UNS S30815, equal to Alloy 253MA and EN 1.4835 , include rare earth metals (REM) and suitable for very high temperature applications (700 1100â„ƒ),particularly for conditions involving erosion corrosion in oxidizing and neutral environments, as well as sulfur attack. The excellent mechanical strength at high temperatures allows higher loads or thinner wall thickness than common high temperature steels e.g. 309S (EN 1.4833) and 310S (EN 1.4845).
