Do Stainless Steel Valves Rust?
Answer: yes.
Why?
Stainless steel valves in some special industries are important, but this valve will not rust?
Not.
Stainless steel is a kind of alloy, common stainless steel austenitic stainless steel, martensitic stainless steel, and ferritic stainless steel, stainless steel in the main components include chromium, nickel, iron, and other elements. Among them, chromium is the key factor that makes stainless steel corrosion-resistant. Chromium in the stainless steel surface forms a layer of extremely thin and strong chromium-rich oxide film, this film can prevent oxygen moisture and other corrosive media to further invade the stainless steel interior, thus playing a protective role. The higher the chromium content, the stronger the corrosion resistance. But when the chromium oxide film is destroyed, stainless steel has the possibility of rust. In high chlorine ion content, in strong acid and alkali or high-temperature environments, this protective film formed by chromium is easy to be destroyed, resulting in stainless steel rust.
So, not rust characteristics of the stainless steel material are relative, not absolute.
