Nov 24,2004·A nitric acid grade (NAG) of very low carbon,silicon and phosphorus to improve resistance to IGA is available.Molybdenum-bearing grades (316) are usually not employed in the nitric acid producing plant due to the susceptibility of molybdenum to oxidation and the adverse effects of certain intermetallic constituents.sp.infoIntroduction of 316 stainless steel bearing ballThe performance is similar to 302/304 stainless steel,but because it contains molybdenum,316 stainless steel has better rust resistance in sulfuric acid compounds.This type of steel ball is generally used on connections that are in contact with ink,photographic chemicals,bleach,dye,or nitric acid.316 stainless steel is the only
