The 409 stainless steel plate materials

409 stainless steel plate refers to the resistance of air, steam, water and other corrosive medium and weak acid, alkali, salt and other chemical etching medium corrosion of 430 stainless sheet , also known as stainless acid resisting steel. In practical applications, often weak corrosion resistant steel known as stainless steel, the corrosion of steel called acid resistant steel. Because of the difference in the chemical composition, the former not resistant to chemical corrosion, and the stainless steel coils  is normally has no rust. Alloy elements in stainless steel corrosion resistance depends on the contained in. 409 stainless steel plate base alloy elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, to meet a variety of uses and properties of stainless steel requirements. So easily by chlorine ion corrosion, chromium, nickel, because chlorine is stainless steel coils manufacturers  elements, isotopic elements will swap assimilation to form corrosion of stainless steel.
