Chemical industry
In the chemical industry, the transport of corrosive media, the general use of PTFE pump and stainless steel magnetic pump, in the choice of stainless steel pump, often encounter, 304316l and other materials of stainless steel pump, so what are the differences between these materials, the use of pump manufacturing performance difference? Stainless steel (stainless steel) is the abbreviation of stainless steel, which is resistant to weak corrosive media such as air, steam, water or stainless steel; and the steel that is resistant to chemical corrosion medium (acid, alkali, salt and other chemical etching) is called acid resistant steel.
Stainless steel refers to the steel which is resistant to the corrosion of weak corrosive media such as air, steam, water and acid, alkali, salt and other chemical corrosive media, also known as stainless acid resistant steel. In practical application, the steel with weak corrosion resistance is often called stainless steel, while the steel resistant to chemical medium corrosion is called acid resistant steel. Due to the difference in chemical composition, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally rust free. The corrosion resistance of stainless steel depends on the alloy elements contained in the steel.
