Stainless Steel 316 316L 316H 316Ti Pipes

On the basis of 316L, many steel grades are also derived, such as 316Ti after adding a small amount of Ti, 316N after adding a small amount of N, and 317L is derived from increasing Ni and Mo content.

Product Introduction

Most of the existing 316L on the market are produced in accordance with the American standard. For cost considerations, steel mills generally put the Ni content of products as close to the lower limit as possible. The American standard stipulates that the Ni content of 316L is 10 ~ 14%, and the Japanese standard stipulates that the Ni content of 316L is 12 ~ 15%.
