Profile: Lord Steel International Co.,Ltd offers stainless steel tubes and pipes. We are forecasting the direction of the market of application of super ferritic stainless steel tubes in condensers and analysis the advantages of super ferritic stainless steel tubes compared with normal austenitic stainless steel tubes & titanium tubes from the aspects of chemical compositions, anti-corrosion capabilities, physical properties and mechanical properties of super ferritic stainless steel tubes. 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.
