309s Stainless Steel Pipe
309s Stainless Steel Pipe
309s stainless steel pipes belong to austenitic stainless steel, which is also a high-alloy steel. Its chemical composition contains a high proportion of chromium and nickel, as well as a small amount of carbon, silicon, manganese and other elements. The proportion and content of these elements have a very important influence on the performance of stainless steel pipes.
- Cr (23%): it improves corrosion resistance and oxidation resistance;
- Ni(12%): it improves high temperature strength and heat resistance.
