316 AND 316L STAINLESS STEEL PLATE OVERVIEW

Grade 316 stainless steel plate is the standard molybdenum-bearing grade of stainless steel plate. The molybdenum gives 316 stainless steel plate better overall corrosion resistant properties than grade 304 stainless steel plate. It has particularly higher resistance to pitting and crevice corrosion in chloride environments. 316 stainless steel plate has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 stainless steel plate also has outstanding welding characteristics. Grade 316L stainless steel plate is the low carbon version of 316 stainless steel plate and is extensively used in heavy gauge welded components.
