High temperature high strength alloy steel X 8 NiCrAlTi 32-21
X 8 NiCrAlTi 32-21 is a fully austenitic low-carbon nickel - iron - chromium alloy in the same series of With X 8 NiCrAlTi 32-21, the cobalt content of alloy can be strictly controlled under 0.01%. X 8 NiCrAlTi 32-21 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. X 8 NiCrAlTi 32-21 alloy steel usually applied in nitric acid condenser, nitric acid corrosion resistance, steam heating pipe and so one which request 500 degree working environment. X 8 NiCrAlTi 32-21 alloy steel usually be delivered with annealed state.
