Grade 304L Stainless Steel for Severely Corrosive Conditions is originally "18-8" stainless steel, much larger than other austenitic stainless steel production, 304 has good corrosion resistance in medium to medium oxidation environment. By controlling the content of nitrogen, 304 l can meet 304 mechanical performance requirements, so most products 304 and 304/304l and have double standards.
