UB6 Plug Valve Manufacturer and Supplier, Factory price for sale in China. UB6 Plug Valve is a very low carbon, high alloying austenitic stainless steel designed for harsh corrosion conditions. UB6 Plug Valve has better corrosion resistance than 316L and 317L Plug valve. At the same time, both price and performance are considered to be cost-effective. Due to the addition of 1.5% copper, excellent corrosion resistance to reducing acids such as sulfuric acid and phosphoric acid. UB6 Plug Valve also has excellent corrosion resistance to stress corrosion, pitting corrosion and crevice corrosion caused by chloride ions, and has good intergranular corrosion resistance.

The chemical composition of UB6 Plug Valve is shown below:
