Stainless steel pipe is a broad term for iron-based alloy steel with chromium content exceeding 13%, which has anti-corrosion and anti-oxidation properties through the passivation of chromium. The main component of the stainless steel pipe is iron. There is just one element that determines the properties of stainless steel pipes, and that is chromium. After adding chromium as an alloying element in steel, it encourages the development of internal molecular motion to help resist oxidation damage. Therefore, the chromium content determines the oxidation resistance of stainless steel.
Is another element called nickel? The role of nickel in stainless steel comes into play only when it cooperates with chromium. Nickel is an excellent corrosion-resistant material and an essential 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 just says, the combination of nickel and chromium mainly plays a role in corrosion resistance.
