A351 CF3 Valve
A351 CF3 Valve are made of ASTM A351 CF3. ASTM A351 CF3 is a cast austenitic corrosion resistant alloy material. A351 CF3 Valves: A351 CF3 ball valves, CF3 gate valves, CF3 globe valves and CF3 check valves.
A351 CF3 valves can be used in severe corrosive environments and meet NACE MR0175.
Key Specifications / Features
A351 CF3 is a lower carbon variant of Grade A351 CF8 – the steel can be welded without the resulting issue of carbon precipitation (precipitation of chromium carbide as heat is applied during the welding process which depletes the chromium element of the steel thus reducing its anti-corrosive/oxidation effectiveness). It’s corrosive and strength properties are similar to A351 CF8.
