X5 NiCrAlTi 31-20

Product:X5 NiCrAlTi 31-20 is a fully austenitic low-carbon nickel - iron - chromium alloy in the same series of With X5 NiCrAlTi 31-20, the cobalt content of alloy can be strictly controlled under 0.01%. X5 NiCrAlTi 31-20 ability a lot of corrosion medium corrosion. Its high content of nickel in the aqueous corrosion condition has the very good resistance to stress corrosion cracking performance. X5 NiCrAlTi 31-20HT alloy steel usually applied in nitric acid condenser, nitric acid corrosion resistance, steam heating pipe and so one which request 500 degree working environment. X5 NiCrAlTi 31-20HT alloy steel usually be delivered with annealed state.

X5 NiCrAlTi 31-20 equal material: W.Nr.1.4876, X10NiCrAlTi3220, Z8NC32.21, NA15, Incoloy 800H, FeNi32Cr21AlTi
