202 stainless steel properties and uses

202 (12Cr18Mn9Ni5N) stainless steel is the most typical Cr-Ni-Mn-N austenitic stainless steel. It is a low-nickel and nickel-saving steel type, which is equivalent to 302 stainless steel. Modified steel has good mechanical properties, technological performance and corrosion resistance, and its room temperature strength is higher than that of 18-8 steel. After solid solution treatment, the steel has good corrosion resistance in reducing media such as organic acids. The steel has good oxidation resistance and medium temperature strength below 800 degrees Celsius. It can work for a long time in the atmosphere below 400 degrees Celsius or in the medium of gas products. 202 stainless steel has a tendency to intergranular corrosion after welding.
202 stainless steel is used to manufacture aero engine stamping parts, structural parts and welded parts that work for a long time under atmospheric conditions below 400 degrees Celsius or gas product medium conditions. It can also be used to manufacture dilute nitric acid underground storage tank, ammonium nitrate vacuum evaporator, engine combustion chamber parts, etc.
