Advantages:
- Less density - 7.280g/cm3 against 8.4 g/cm3 for Cr20Ni80. let economize till 13% on the weight;
- More high electric resistance in comparison with Cr20Ni80.
- Heat-resistances in the atmosphere: oxidative, contain sulphur and sulphide, carbonic, in hydrogen and in vacuum. Disadvantages:
- They are inclined the creeping and the deflection at high temperatures
