Z8NC32.21 High temperature high strength alloy steel
Z8NC32.21 is a fully austenitic low-carbon nickel - iron - chromium alloy in the same series of With Incoloy 800 steel,the cobalt content of alloy can be strictly controlled under 0.01%.Z8NC32.21 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. Z8NC32.21alloy steel usually applied in nitric acid condenser, nitric acid corrosion resistance, steam heating pipe and so one which request 500 degree working environment.Z8NC32.21alloy steel usually be delivered with annealed state.
