3. Characteristics of iron-chromium-aluminum electrothermal alloys:
, high operating temperature in the atmosphere
The maximum operating temperature of the alloy in the alloy can reach ℃, while the alloy in The maximum operating temperature is ℃.
, long service life
Under the same high operating temperature in the atmosphere, the life of iron-chromium-aluminum components can be twice that of nickel-chromium components.
High surface load
Since iron-chromium-aluminum alloy allows high operating temperatures and long service life, the surface load of components can also be higher, which not only makes the temperature rise faster but also saves alloy materials.
, good anti-oxidation performance
The 3 oxide film generated on the surface of the iron-chromium aluminum alloy has a dense structure, good adhesion to the substrate, and is not easy to scatter and cause pollution due to running water. In addition, 3 has high resistivity and high melting point. These factors determine that the 3 oxide film has excellent oxidation resistance. The carburization resistance is also better than that produced on the surface of nickel-chromium alloy.
, small specific gravity
The specific gravity of iron-chromium-aluminum alloy is smaller than that of nickel-chromium alloy, which means that when making the same components, iron-chromium-aluminum saves more material than nickel-chromium.
, high resistivity
The resistivity of iron-chromium-aluminum alloy is higher than that of nickel-chromium alloy. When designing components, larger alloy materials can be selected, which is beneficial to extending the service life of components. For fine alloys Line is particularly important.
, good sulfur resistance
Iron, chromium and aluminum have good corrosion resistance in sulfur-containing atmospheres and when the surface is contaminated by sulfur-containing substances, while nickel and chromium will be severely corroded.
The main disadvantages of iron-chromium-aluminum alloys are low high-temperature strength. As the temperature increases, their plasticity increases, easily causing component deformation
and low price
Since iron-chromium-aluminum does not contain nickel, The price is much cheaper than nickel-chromium
