What is the difference between 304 stainless steel and 316 stainless steel

1. Different chemical composition 304 is cap stainless steel, its material composition is 　OCr18Ni9, 316L is austenitic stainless steel, and the material composition is OOCr12Mo2Ti. 2. Different performances 304 steel is resistant to corrosion by sulfuric acid, phosphoric acid, formic acid, urea, etc. It is suitable for general water, control gas, wine, milk, CIP cleaning fluid and other occasions with little corrosivity or no contact with materials. 316L steel grade has added molybdenum element on the basis of 304, which can significantly improve its resistance to intergranular corrosion and oxide stress corrosion and reduce the tendency of hot cracking during welding. It also has good resistance to chloride corrosion. Commonly used in pure water, distilled water, medicines, sauces, vinegar and other occasions with high hygiene requirements and strong media corrosion properties. The price of 316L is almost twice that of 304. 3. Different maintenance methods. 304 stainless steel: 18cr-8ni-0.08c has good corrosion resistance, oxidation resistance and processability, strong oxygen acid resistance, can be punched, and can be used to make containers, tableware, metal furniture, architectural decoration, and medical treatment appliance. 316 stainless steel: 18cr-12ni-2.5Mo is more common in seaside construction, ships, nuclear electrochemistry and food equipment, etc. It not only improves the corrosion resistance to chemical hydrochloric acid and the ocean, but also improves the corrosion resistance to salt water halogen solution Sex.
