What is the difference between 304 و 316 الفولاذ المقاوم للصدأ?

May 20, 2019

 

Chemical composition
304 is a cover type stainless steel, and its material composition is OCr18Ni9, 316L is austenitic stainless steel, and its material composition is OOCr12Mo2Ti.

Performance of different
ال 304 steel can resist the corrosion of sulfuric acid, phosphoric acid, formic acid, urea, إلخ.
The addition of molybdenum to the 304 base of 316L steel can significantly improve its resistance to inter-granular 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.

Different maintenance methods
304 الفولاذ المقاوم للصدأ: 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 الفولاذ المقاوم للصدأ: 18cr-12ni-2.5Mo is common in seaside buildings, ships, nuclear power chemical and food equipment, إلخ. It not only improves the corrosion resistance of hydroelectric acid and Marine chemicals, but also improves the corrosion resistance of brine halogen solution.

Use
304 stainless steel is mainly used for corrosion resistant containers, tableware, furniture, railings, medical equipment. ال 316 stainless steel is mainly used in the food industry, watch and watch accessories, pharmaceutical industry and surgical equipment.
