Grades features applications 304 austenitic stainless steel with ni content more than 8%, Food, Grade alloy. Can serve the aim of to cast stainless steel components for both household and commercial applications. Widely used stainless steel casting material. 304 stainless steel castings can be used in environments where the air is less corrosive. Medical,, Automotive industry, Food industry, Pipe industry, Mechanical equipment, Chemical industryetc. 316 also austenitic stainless steel with ni content exceeding 10%. For their higher ni content, 316 stainless steel castings have better corrosion resistance than 304 stainless steel castings. Such stainless steel castings better suit the marine environment with relatively harsh air conditions or chemical materials that need to be contacted. Fire fighting, Auto parts, Marine hardwares, Chemical, Pipeline, Construction, Decoration, Food industry, Etc. 304l / 316l the mechanical properties are close to those of 304 and 316 materials. L represents lower that allows, Carbon content for the material has good, More ductile welding performance, And has more reliable protection against corrosion price is higher than that of materials of the same grade. Food, Chemical, Medical, Plumbing, Etc.
