High temperature high strength alloy steel N08811 HT
N08811 is a fully austenitic low-carbon nickel - iron - chromium alloy in the same series of With N08811, the cobalt content of alloy can be strictly controlled under 0.01%. N08811 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. N08811alloy steel usually applied in nitric acid condenser, nitric acid corrosion resistance, steam heating pipe and so one which request 500 degree working environment. N08811 alloy steel usually be delivered with annealed state.
