Stainless Steel Tubing – Composition and Applications
Stainless steel is an iron alloy with a minimum chromium content of 10.5 percent. Chromium prevents corrosion by producing a thin layer of oxide on the surface of the steel. Increasing the amount of chromium gives an increased resistance to corrosion.
Stainless steel also contains manganese, carbon, and silicon in varying proportions. Other elements such as nickel and molybdenum are also commonly added to increase formability and corrosion resistance.
