NS3303/ NS333 steel
NS3303/ NS333Wrought nickel-base superalloy
Equal material : NS3303/ NS333

1.NS3303/NS333 main description:
 NS3303/ NS333 which is on the basis of Hastelloy alloy B adding elements of Cr, w, Ni - Cr alloy and N i.M o is compatible and optimization, in the oxidizing and reducing medium has good corrosion resistance and resistance to local corrosion, resistance to chloride stress corrosion cracking and pitting corrosion of sea water. Hastelloy C there are some serious drawbacks, in demanding oxidation medium, the alloy of chromium content is not enough to keep its passivation state and showed high uniform corrosion rate;More applications obstacle is the welding heat affected zone in many oxidizing, low pH, halide environment is sensitive to intergranular corrosion.
2.NS3303/ NS333 Physical properties:
NS3303/ NS333 Density: 8.94 g/cm3
NS3303/ NS333 Melting point: 1350 degree

Key words: NS3303 stock, NS3303 competitive price, NS3303 high quality, NS3303 supplier, NS3303 manufacturer.
