The composition of the alloy and its application
Nichrome Х20Н80 (2.4869 or Ni80Cr20 according to DIN 17470/17471) is a high-quality precision chromium-nickel alloy of austenitic class. Due to its corrosion resistance in air and strength at high temperatures, the alloy is particularly suitable for use in the industry engaged in the manufacture of measuring electrical appliances. In industrial furnaces, the use of flat nichrome (plyuschki) from the alloy grade X20N80 has many advantages due to its excellent mechanical properties in the hot state.
This alloy has excellent durability compared to materials of similar purpose (for example, feces) because of the extremely good adhesion properties of the oxide that forms on the surface.
Typical products of flat nichrome plyuschinki of the alloys X20N80, Ni80Cr20, (2.4869) are the electric chains of ironing machines, water heaters, as well as resistors, plastic molding molds, flat soldering tips, metal casings with cylindrical elements, cartridge elements, etc.
The chemical composition of the precision alloy Kh20N80 with a high electrical resistance value, manufactured according to the technical requirements of GOST 10994−74 (numerical data — in percent, nickel-base) is given in the table:
| Fe | C | Si | Mn | S | P | Cr | Ti | Al | Zr |
| Not more than 1 | Not more than 0.06 | 1… 1.5 | Not more than 0.6 | Not more than 0.015 | Not more than 0.02 | 20… 23 | Not more than 0.2 | Not more than 0.2 | 0.2… 0.5 |
