S30800
06Cr20Ni11Overview and features of 308:
308 is a typical austenitic stainless steel. It is also known as a type of chromium-nickel stainless steel. It is suitable for the welding parts working at high temperatures. The element of titanium can prevent the intergranular corrosion to some extent. It is generally used at the temperature between 430℃ and 900℃. 308 can be applied in aircrafts, exhaust pipes, boiler drums, etc.Chemical composition of 308 (%):
