At present 316 and 316L stainless steel in the market has been widely used, and 316 and 316L stainless steel itself there are differences, so there are also different in the role, so how should we distinguish their role, then I need to see the difference from them.

The first is the different properties. 316L is a kind of stainless steel material, AISI 316L is the corresponding American grade, SUS 316L is the corresponding Japanese grade. China's uniform digital code for S31603, the standard grade for 022CR17NI12MO2 (new standard), the old grade for 00CR17NI14MO2, said it mainly contains Cr, Ni, Mo, the number says it probably contains a percentage.

316 stainless steel is a kind of austenitic stainless steel, because of the addition of Mo element, so that its corrosion resistance, and high temperature strength has been greatly improved, high temperature resistance can reach 1200-1300 degrees, can be used under harsh conditions.

Second characteristics are different, 316L because of its excellent corrosion resistance in the chemical industry has a wide range of applications, 316L also belongs to the 18-8 type austenitic stainless steel derived steel, added with 2 ~ 3% Mo element. On the basis of 316L, many kinds of steel are also derived. For example, 316Ti is derived after adding a small amount of Ti, 316N is derived after adding a small amount of N, and 317L is derived by increasing the content of Ni and Mo.

The corrosion resistance of 316 stainless steel is better than that of 304 stainless steel. It has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to Marine and aggressive industrial atmosphere erosion.
