Product Introduction

316 316l ss pipe tube

What is double standard stainless steel?

Double standard stainless steel refers to the optimization of two kinds of materials, such as 316 and 316L, starting the double standard is to take the high nickel content of 316, and then take the low carbon content of 316L, calmly and form a double standard material, its performance is better.
In addition to the double standard material, there are four standard materials, such as 1.4404/1.4401/316L/316 to form a lower carbon content, Cr content is better, nickel content is higher, and the performance is optimized.
Double standard or four standard is a new material, in simple terms, this new material can be used to make seamless pipes, can also be used to make welded pipes, can also be used to process into plates.
