Advantages of ferrochrome electric heat alloy
High temperature is used in the atmosphere
HRE alloy of iron chromium aluminum alloy electrical highest temperature can reach 1400 ℃, the highest Cr20Ni80 alloy of nickel and chromium electrothermal alloy using temperature is 1200 ℃.
Long service life
At the same high temperature in the atmosphere, the chromium aluminum element can live 2-4 times as long as nickel chromium.
Due to the high temperature and long life, the surface load of the element can be higher, which not only makes the heating fast, but also saves the alloy material.
Good oxidation resistance
The structure of Al2O3 oxide on the surface of ferrous chromium aluminum alloy is compact, and it is good for adhesion of the substrate, and it is not easy to be contaminated by the scattering.In addition, Al2O3 has high resistivity and high melting point. These factors determine the excellent oxidation resistance of Al2O3 oxide film.The anti-carburizing performance is also better than the Cr2O3 generated on the surface of nickel-chromium alloy.
The proportion of small
The ratio of chromium to chromium alloy is smaller than nickel chromium alloy, which means that it is more efficient to use chromium aluminium than nickel chromium when making the same components.
Resistivity than the nickel chrome iron chromium aluminum alloy of high, when the design components can choose bigger specifications of alloy materials, which is beneficial to prolong the service life of components, it is particularly important for fine alloy wire.When the same material is used for the same specification, the higher the resistivity, the less the components are in the furnace.In addition, the resistivity of ferrochrome aluminium alloy is less affected by cold processing and heat treatment than nickel chromium alloy.
Good anti-sulfur performance
Iron chromium aluminum has good corrosion resistance to sulfur-bearing atmosphere and sulfur-containing substances, while nickel chromium can be severely eroded.
Iron chromium aluminium is much cheaper than nickel chromium because it does not contain more scarce nickel.
