As we all know that the valve body like carbon steel (WCB, WCC, LCB, LF2, A105), stainless steel (SS304, SS316, F304L, F316L), hastelloy (Alloy 20) etc., or even in the trim material always use metallic materials. Most of the corrosion of metallic materials occurs in the atmosphere, which contains corrosive components and corrosive factors such as oxygen, humidity, temperature changes and pollutan...
