High temperature high strength alloy steel W.Nr.1.4959

High temperature high strength alloy steel W.Nr.1.4959

W.Nr.1.4959 is a fully austenitic low-carbon nickel - iron - chromium alloy in the same series of With W.Nr.1.4959 the cobalt content of alloy can be strictly controlled under 0.01%. W.Nr.1.4959 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.1.4959 alloy 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.1.4959 alloy steel usually be delivered with annealed state.
