28 austenitic stainless steel 0Cr 18Ni9
Stainless steel with austenitic structure at room temperature. When the chromium content is about 18%, the nickel content is about 8% ~ 10%, and the carbon content is about 0. 1%, the steel has a stable austenite structure. Austenitic Cr-Ni stainless steel includes the famous 18Cr-8Ni steel and the high Cr-Ni series steel developed by adding Mo, Cu, Si, Nb and Ti. Austenitic stainless steel is nonmagnetic and has high toughness and plasticity, but its strength is low, so it can not be strengthened by phase transformation, but only by cold working. If sulfur, calcium, selenium, tellurium and other elements are added, it has good cutting performance. In addition to the corrosion resistance of oxidizing acid medium, this steel can also resist the corrosion of sulfuric acid, phosphoric acid, formic acid, acetic acid and urea if it contains elements such as Mo and Cu. If the carbon content in this steel is less than 0.03% or contains Ti and Ni, its intergranular corrosion resistance can be significantly improved. High silicon austenitic stainless steel has good corrosion resistance in concentrated nitric acid. Austenitic stainless steel is widely used in all walks of life because of its comprehensive and good comprehensive properties.

Some steels also contain alloying elements, such as molybdenum, copper, silicon, niobium, titanium and nitrogen. This steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferritic steel, it has higher plasticity and toughness, no brittleness at room temperature, significantly improved intergranular corrosion resistance and weldability, and maintained the brittleness, high thermal conductivity and superplasticity of ferritic stainless steel at 475℃. Compared with austenitic stainless steel, it has high strength and obviously improved intergranular corrosion resistance and chloride stress corrosion resistance. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.
