Product Introduction

a312 tp316 316l

First, the nature is different

1, 316L: 316L is a stainless steel material grade, AISI 316L is the corresponding American label, sus 316L is the corresponding Japanese label. China's unified digital code is S31603, the standard grade is 022Cr17Ni12Mo2 (new standard), and the old grade is 00Cr17Ni14Mo2, which mainly contains Cr, Ni, Mo, and the number indicates the approximate percentage contained.

2, 316 stainless steel: 316 stainless steel is a kind of austenitic stainless steel, due to 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, different characteristics

1, 316L: 316L has a wide range of applications in the chemical industry because of its excellent corrosion resistance, 316L is also a derivative steel of 18-8 austenitic stainless steel, adding 2 ~ 3% Mo element. 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. Calendar delay

2, 316 stainless steel: corrosion resistance is better than 304 stainless steel, in the pulp and paper production process has good corrosion resistance. And 316 stainless steel is also resistant to the erosion of the ocean and aggressive industrial atmosphere.
