What is the difference between 304 and 316 stainless steel
1. Different chemical composition
The 304 is covered stainless steel, and its material composition is OCr18Ni9.
The 316L is austenitic stainless steel, and the material composition is OOCr12Mo2Ti.
2. Different performance
The 304 steel can resist the corrosion of sulfuric acid, phosphoric acid, formic acid, urea, etc.
The addition of molybdenum to the 304 base of 316L steel can significantly improve its resistance to intergranular corrosion, oxidative stress corrosion and thermal cracking tendency during welding, as well as its good resistance to chloride corrosion.Used for pure water, distilled water, medicine, sauce, vinegar and other health requirements, medium corrosion strong occasions.The price of 316L is almost double that of 304.
3. Different maintenance methods
304 stainless steel: 18cr-8ni-0.08c good corrosion resistance, oxidation resistance and processing, strong oxygen resistance and acid resistance, can be stamped, can make containers, tableware, metal furniture, architectural decoration, and medical appliances.
316 stainless steel: 18cr-12ni-2.5Mo is common in seaside buildings, ships, nuclear power chemical and food equipment, etc. It not only improves the corrosion resistance of hydrochloric acid and Marine chemicals, but also improves the corrosion resistance of brine halogen solution.
