Grade 347 Stainless Steel
347 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 321 stainless except it uses niobium to stabilize the carbon instead of titanium. This improved corrosion resistance allows this grade to be used in service at much higher temperatures close to 1500oF. These applications include high temperature gaskets, expansion joints, exhaust manifolds and rocket engine parts.
