Huzhou Nanxun Yintuo Special Material Technology Co., Ltd. mainly provides the development and production of Stainless Steel Seamless Pipe. These include Austinitic Stainless Steel Seamless Tube, if you want to know more, please continue reading.
Stainless steel plate is often referred to as "corrosion resistant steel"-it is not as easy to stain, corrode or rust like ordinary carbon steel.
Duplex stainless steel is an extremely corrosion-resistant, work-hardenable alloy. Duplex stainless steel plates contain relatively high levels of chromium (between 18% and 28%) and small to moderate amounts of nickel (between 1.5% and 8%). The high corrosion resistance and excellent mechanical properties of duplex stainless steel can be attributed to its chemical composition and a balanced (duplex) microstructure with approximately equal volume percentages of ferrite and austenite. Due to this dual nature, it will show the characteristics of austenitic and ferritic stainless steel. In most cases, duplex stainless steel is harder than ferritic stainless steel. In some cases, the strength of duplex stainless steel can be twice that of austenitic stainless steel.
Duplex stainless steel has an α+γ duplex structure, so it is characterized by the performance characteristics of austenitic stainless steel and ferritic stainless steel. It is a high-strength and corrosion-resistant stainless steel. Generally, in the case of low Cr, the C content is 18%-28%, and the Ni content is 3%-10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloying elements.
Compared with ferrite, plasticity, toughness and brittleness at room temperature, grain boundary corrosion resistance and welding performance have been significantly improved, while maintaining 475 degrees ferritic stainless steel and high thermal conductivity, with high plasticity characteristics. Compared with austenitic stainless steel, the yield strength is significantly improved, the grain boundary corrosion resistance, the stress corrosion, corrosion fatigue and wear performance are significantly improved.
We are enterprising with a firm attitude, but at the same time, we are also watching the stars and ambitious ambitions. We are the supplier of Duplex Stainless Steel Pipe, if you are interested and want to buy stainless steel seamless pipe, please contact us!
