309S stainless steel is an austenitic chromium-nickel stainless steel, and 309S stainless steel is also a derivative steel with reduced carbon content on the basis of 309 stainless steel.
The corrosion resistance and heat resistance of 309S stainless steel are better than 304 stainless steel. 309S stainless steel can withstand repeated heating below 980°C. 309S stainless steel has high high temperature strength, oxidation resistance and carburization resistance. 309S stainless steel has high chromium content and low nickel content. 309S stainless steel can be used in the atmosphere with the largest sulfur content, and the heat resistance temperature is 1000 degrees.
Heat-resistant steel 309S stainless steel plate has high high temperature strength, oxidation resistance and carburization resistance. Therefore, heat-resistant steel 309s stainless steel plate can be widely used in boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, heating furnaces, chemical, petrochemical and other important fields.
