Stainless steel flap disc corrosion resistance depends mainly on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal organizational structure, play a major role in the chromium. Chromium has a high chemical stability, can form a passive film on the steel surface, the metal with the outside world to isolate and protect flap disc is not oxidized, to increase the corrosion resistance of the flap disc. After the destruction of the passive film, corrosion resistance on the decline.
stainless steel flap disc surface finish, higher ductility, toughness and mechanical strength, acid and alkaline gases, solvents and other media. It is a rusty steel is not easy, but not definitely not rust. stainless steel flap disc refers to resistance to air, steam and water and other weak corrosive medium steel, while acid flap disc refers to acid, alkali, salt and other chemical etching medium corrosion of the flap disc.
