Stainless steel gas-liquid filter product features are: anti-air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical etching medium corrosion of steel.Also known as acid-resistant stainless steel.Practical applications would often weak corrosive medium corrosion-resistant steel known as stainless steel, which will be resistant to chemical corrosion of steel known as the acid medium steel.

Because of the difference in the chemical composition differences, the former is not necessarily resistant to chemical corrosion medium, while the latter generally has a stainless nature. Corrosion resistance of stainless steel depends on the alloying elements contained in steel.Chromium is to corrosion resistance of stainless steel to obtain the basic elements,when the steel contains up to 12% of chromium, the chromium and oxygen in the corrosion medium role in the steel surface to form a thin oxide film (since the passive film),can prevent the further corrosion of the steel substrate.In addition to chromium, the commonly used alloying elements are nickel, molybdenum, titanium, niobium,copper, nitrogen,in order to meet a variety of uses and properties of stainless steel requirements.Stainless steel gas-liquid filter generally required to use acid-resistant steel.
