Stainless steel is widely used in our life, and stainless steel can be seen everywhere. So what is the difference between stainless steel 304 and 316? Today, Aozhan Hardware Fasteners will explain to you.
A.304 and 316 chemical composition is not the same
304, 316 is the American standard, 3 on behalf of the 300 series steel, the last two digits are serial number. 304 Chinese grade is 06Cr19Ni9 (containing less than 0.06% C, 19% more than chromium, 9% more than nickel); 316 Chinese grade 06Cr17Ni12Mo2 (containing less than 0.06% C, 17% more than chromium, 12% more than nickel, 2% more than Molybdenum).
We can know from the grade, 304 and 316 contain different chemical composition, and the biggest difference between the different components is that the acid corrosion resistance is not the same. 316 stainless steel compared to 304 in terms of nickel Ni elements have increased, in addition to the new molybdenum Mo elements. Increased nickel elements can further improve the durability of stainless steel, mechanical properties, oxidation resistance. The element of molybdenum can improve atmospheric corrosion, especially the atmospheric corrosion containing chlorides. So 316 stainless steel in addition to having the performance characteristics of 304 stainless steel, but also resistant to special media corrosion, can improve the corrosion resistance to chemicals and marine, improve the corrosion resistance of salt water halogen solution.
B. The application scenarios of 304 and 316 are not the same
304 stainless steel is used in an extremely wide range of applications, such as desks and kitchenware, architectural decoration, food industry, agriculture, ships, sanitary ware, automotive parts and so on.
The price of 316 stainless steel will be higher than that of 304, compared with 304, 316 stainless steel is a little more acid-resistant and better stability. 316 stainless steel is mainly used in chemical, dye, paper, acetic acid, fertilizer and other production equipment, food industry and coastal facilities, and products with special requirements against intergranular corrosion.
The above is the difference between stainless steel 304 and 316, I hope it will be helpful to you.
