NA15 High temperature high strength alloy steel

NA15 High temperature high strength alloy steel
NA15 is 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%. NA15 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. NA15alloy steel usually applied in nitric acid condenser, nitric acid corrosion resistance, steam heating pipe and so one which request 500 degree working environment.
