Nickel chromium alloy W.Nr.2.4851 is designed for a heat resistant, high temperature environment design, high strength, corrosion resistance and oxidation at high temperature and corrosive environment commonly used alloy material, has good oxidation resistance, anti carburizing resistance and sulphurizing performance. Under the environment of high temperature, oxidation resistance of the alloy is particularly prominent, has excellent resistance to oxidation skin off for the cyclic oxidation. Mechanical strength, but also have high easy forming, and has good processing properties and weldability.
