316L

316L has a widely used in the chemical industry because of its excellent corrosion resistance,  316L is derivative steel 18-8 type Austenitic stainless steel, adding 2 ~ 3% of Mo element.
On the basis of 316L, also derived from many kinds of steel, such as adding a small amount of Ti derived after 316 Ti, adding a small amount of N derived from 316N, increasing the content of Ni and Mo derived 317.
