Product Description
The steel is adjusted its Mo and C content and added with N; it has characteristics such as high intensity, chloride stress corrosion resistance and weldability; it is a kind of steel that has the best corrosive pitting resistance and can replace 0Cr26Ni5Mo2.
The steel is mainly used in making exchanger and evaporimeter of chemical industry, chemical fertilizer industry, petrochemical industry, etc.
Austenitic-Ferritic Stainless Steel is intermediate in terms of structure and alloy content between Ferritic and Austenitic Stainless Steel. The main characteristic that differentiates Austenitic-ferritic steel Bar from austenitic and ferritic steel is that they have a higher yield strength and tensile strength. We can supply X2CrNiMoN22-5-3, SUS329J4L and other Austenitic-Ferritic Stainless Steel for dynamically stressed machine parts, etc.
Austenitic-Ferritic Stainless Steel presents higher mechanical and corrosion resistance properties and its yield strength is about twice that of standard austenitic grades. Operation temperature of this kind of alloy is generally limited from -50°C to 280°C (- 58°F to 536°F). Lower temperature used particularly for welded structures may also be considered, but technical background is needed.
The idea of duplex stainless steels can be traced back to the 1920s with the first cast being made at Avesta in Sweden in 1930. However, it is only in the last 30 years that Austenitic-Ferritic duplex stainless steels have begun to "take off"in a significant way, many steel making enterprises have strengthened their ability on making duplex stainless steel and the ability is matured step by step, such as Jinsong stainless steel is one of those experienced stainless steel manufacturer and supplier. This is mainly due to advances in steelmaking techniques particularly with respect to control of nitrogen content, and to minimize the weakness of both austenitic steels and ferritic steels.
The basic idea of producing duplex stainless steel is to achieve a balance of phases by making a chemical composistion to leads to an approximately equal mixture of ferrite and austenite.
