Composition
The name "Fehral" is made up of the names of its constituent parts: ferum - "Fe", chromium - "Chr", aluminum - "Al". The basis of the alloy is iron. Its share in the alloy, as a rule, is over 70%. The alloy is further alloyed with manganese, silicon, and possibly with nickel.

|---|---|---|---|---|---|---|---|---|
| X23YU5T | ≤0.50 | ≤0.05 | 22.0-24.0 | ≤0.30 | basis | 5.00-5.80 | 0.2-0.5 | ≤0.60 |
| X23U5 | ≤0.60 | ≤0.05 | 21.5-23.5 | ≤0.30 | basis | 4.60-5.30 | 0.15-0.40 | ≤0.60 |
| X13Y4 | ≤0.70 | ≤0.08 | 13.5-15.5 | ≤0.70 | --- "--- | 4.00-5.50 | 0.2-0.6 | ≤0.60 |
| X15U5 | ≤0.70 | ≤0.08 | 14.5-15.5 | ≤0.70 | basis | 4.50-5.50 | 0.2-0.6 | ≤0.60 |
Alloys combine high electrical resistance (1.05-1.40 Ohmm2/m) with high heat resistance. They are used for the production of high-temperature electric heaters.
