The role of chromium and nickel in stainless steel pipes

The role of chromium and nickel in stainless steel pipe 2018-11-13 Stainless steel pipe is a general term for iron-based alloy steel with anti-corrosion and anti-oxidation properties through the passivation effect of chromium with a chromium content of more than 13%. In fact, the main component of stainless steel pipe is iron. There is only one element that determines the properties of stainless steel pipes, and that is chromium. The addition of chromium as an alloying element in steel promotes the development of its internal molecular motion to help resist oxidative damage. Therefore, the content of chromium determines the oxidation resistance of stainless steel. The content of chromium in stainless steel 201 stainless steel pipe is 13.2-14.5%, and the main function of chromium in stainless steel is oxidation resistance. There is also an element called nickel. The content of nickel in stainless steel is 1.01-1.28%, and the role of nickel in stainless steel can only be brought into play with chromium. Nickel is an excellent corrosion-resistant material and an important alloying element of alloy steel. The role of nickel and chromium in stainless steel is to change the structure of high chromium steel, thereby greatly improving the corrosion resistance and process performance of stainless steel. That is to say, the combination of nickel and chromium mainly plays a role in corrosion resistance.
