Affecting for rust of steel pipe made by contents of alloying elements

Generally speaking, stainless steel pipe would have brilliant corrosion resistance. However, according to manufacturer of various steel pipes, Threewaysteel pipe company would say that for different steel pipes, from seamless steel pipe, ERW steel pipe to SSAW steel pipe, we should pay attention to elements in steel pipe's making to get the accurate data for protecting corrosion resistance.

Taking LSAW steel pipe of API 5L Gr.B from Threewaysteel pipe for instance. The following list is the relative elements in different standard’s steel pipe:

According to the list, we would figure out that it would affect the performance of the steel pipes. For example, the content of chromium in 10.5% steel is not easy to rust. Under this situation, some clients would adopt this steel plan for engineering project. With higher the content of chromium and nickel, the better the corrosion resistance, such as 304 material nickel content of 8-10%, chromium content of 18-20%, such a 304 stainless steel angle in general is not rusty, we can change the steel pipe’s making plan according to customers’ demands.
