Alloy-20 Valve

Alloy-20 is a nickel–chromium–molybdenum alloy developed for applications involving sulfuric acid. Its corrosion resistance also finds other uses in the chemical, food, pharmaceutical, power generation and  plastics  industries. Alloy-20 is not a stainless steel but a nickel alloy (ASTM). Alloy-20 valves include Gate Valves, Globe Valves,Ball Valves, Non Return ValvesAlloy-20 Valves can be used in industries such as  chemical, oil and gas, Marine, Metallurgy, Oil refining, etc.
