Alloy 20 Sleeved Plug Valve Application:
Alloy 20 Sleeved Plug Valve material chromium and nickel content is higher than the ordinary 304,316 stainless steel, so relatively, better corrosion resistance, can be used for the following corrosive media: sulfuric acid, nitric acid, phosphoric acid, organic acid, mixed acid, sulfite, salt solution, alkali, hydrogen sulfide, etc. But 
Alloy 20 Sleeved Plug Valve is not resistant to high temperature concentrated hydrochloric acid, as well as wet fluorine, chlorine, bromine, iodine, aqua regia, etc.

Alloy 20 Sleeved Plug Valve has many excellent properties of corrosion resistant alloy, has good resistance to oxidation and medium reducing corrosion, has excellent stress corrosion cracking resistance and good local corrosion resistance, and has satisfactory corrosion resistance in many chemical process media. Alloy 20 Sleeved Plug Valve has excellent corrosion cracking resistance and good resistance to local reducing composite medium corrosion, used in sulfuric acid environment and containing halogen ions and metal ions of sulfuric acid solution industrial equipment.
