W.Nr.1.4876 High temperature high strength alloy steel

W.Nr.1.4876 High temperature high strength alloy steel
W.Nr.1.4876is a fully austenitic low-carbon nickel - iron - chromium alloy in the same series of With Incoloy 800, the cobalt content of alloy can be strictly controlled under 0.01%.W.Nr.1.4876 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. W.Nr.1.4876alloy steel usually applied in nitric acid condenser, nitric acid corrosion resistance, steam heating pipe and so one which request 500 degree working environment.W.Nr.1.4876alloy steel usually be delivered with annealed state.
