FeNi32Cr21AlTi High temperature high strength alloy steel
FeNi32Cr21AlTiis 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%. FeNi32Cr21AlTi 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. FeNi32Cr21AlTi alloy steel usually applied in nitric acid condenser, nitric acid corrosion resistance,steam heating pipe and so one which request 500 degree working environment. FeNi32Cr21AlTialloy steel usually be delivered with annealed state.
