The wire is made of an alloy of nickel-based HN75MBTYU (also found another name of the alloy — EI602). It is an indispensable component in the production of equipment parts operating at high temperatures: parts of the combustion chambers, welding electrodes, electrical impedance node installations. Welding electrodes and wire HN75MBTYU used for surfacing of parts and welding of various metal constructions in mechanical engineering.

This alloy has a density of 8.3 g / cm³, refers to hromonikelmolibdenovym alloys (Cr — Ni — Mo). It has a high resistance to a wide range of corrosive environments. Tensile strength alloy 900−930 MPa. Balancing content of basic and additional alloying elements of the alloy (W, Nb, Fe, etc.). Guarantee a high level of resistance to corrosion in difficult operating conditions. Prolonged use of the recommended t ° 950 ° C. Heat resistance of the alloy allows for a short time to reach a maximum operating temperature up to 1050 ° C. Above t ° 1050−1100 ° C in the air begins to rapidly formed scale. For a variety of qualities of this steel is superior to similar marks. At a temperature of 20 ° C HN75MBTYU wire has the following mechanical properties:
- Tensile strength is 930 MPa;
- elongation at break — 47%;
- proportional limit (yield point to permanent deformation) is equal to 400 MPa;
- Reduction of 37%;
- produce hardening heat treatment process at a temperature from 1050 to 1080 ° C with air cooling.
The physical properties of the material from which the wire is made as follows:
- first kind modulus is 1.37 MPa;
- the temperature coefficient of (linear) expansion (temperature range 20 ° C) is 18.1 1 / Grad;
- thermal conductivity (heat of the material) is 24.4 W / (m • deg);
- alloy density of 8.3 g / cm³,
