Grade 321 Stainless Steel
321 is an austenitic stainless steel that is melted as AOD melt type. This is a stabalized version of 304 stainless to help improve intergranular corrosion resistance. This alloy is similar to 347 stainless except uses titanium to stabilize the carbon instead of niobium. The improved corrosion resistance allows this grade to be used in service at much higher temperatures close to 1000oF. These high temperature applications include aircraft applications such as exhaust manifolds and expansion joints.
