High resistance Nickel chromium wire to corrosion became the basis of wide application in modern industry in metallurgy, motor industry, gas industry and other industries. Among the advantages of wire brand KHN75MBTJU-VD — not only high resistance to aggressive media, but also flexibility, excellent processability, heat resistance to enable its use at high temperatures up to 950 °C. the Alloys of Nickel, despite its relatively high cost, have a set of unique qualities that are guaranteed to outweigh the initial costs. Nickel forms on the surface of the protective oxide film that protects wire KHN75MBTJU-VD from the action of corrosive industrial environments ensures the reliability and heat resistance at high-temperature modes of operation.
The percentage KHN75MBTJU-VD GOST 5632−72
The scope of the wire KHN75MBTJU-VD is very wide. A manufacturer of fixtures, fittings piping systems, springs, high-temperature parts of the combustion chambers of gas turbine engines operating at t º 950 °C. Another important quality of wire KHN75MBTJU-VD is its good weldability, so it can be used for surfacing and welding of chromium-Nickel alloys.
