5 Types of Stainless Steel used in Process Piping

Stainless steel (SS) is alloy steel with a minimum chromium content of 10.5 % or more, and maximum carbon content of less than 1.20%. SS has excellent resistance to corrosion and good ductility. Stainless steel becomes corrosion resistive due to the formation of non-reactive chromium oxide (Cr2O3) film that adheres tightly to the surface of the metal.

Why Stainless Steel is the Perfect Fit When Corrosion ...

26-07-2018· Stainless steel, a ferrous alloy that contains at least 10 percent chromium, is the most common type of steel hydraulic fitting. It contains the strength and durability of steel and has a strong chemical and corrosion resistance that suits hydraulic applications, especially where the fluid or surrounding environment is corrosive.
