Stainless steel wire KHN78T high heat resistance is a complex mixture of nine main elements. Brand KHN78T may be referred to as ЭИ435. Foreign analogs: 2.4951NiCr20Ti (Germany), GH3030 (China). Nickel base provides a high plasticity. This greatly facilitates cold rolled. The main alloying elements forms a surface oxide film which protects the wire from corrosion and is easily restored, if damaged. At t° 1100 °C the speed of surface oxidation is 0.2 mm. Chromium improves the chemical resistance, heat resistance, and the titanium wire attached to the structural uniformity and strength.

Such expensive metals as chrome, Nickel, chrome, titanium in the alloy composition KHN78T affect its cost. But high strength, reliability and durability of the tape, the possibility of recycling of material reduces the cost of virtually long-term investment.
Properties at 20°C
Limit short-term strength of 880 MPa and reduced at 1100 °C up to 40 MPa. Yield strength not exceeding 300 MPa, the lowest value is 98 MPa at t° 800 °C, after which the rate begins to increase. To 1100 °C it increases to 105 MPa. Elongation at break to 40%. At 900 °C recorded the maximum elongation of 90%. The specific weight of 8.38 g/cm3; modulus of elasticity of the 1st kind of 2.19 MPa; coefficient of linear expansion is 12.2 [1/Deg]; the heat Capacity to 14.6 W/(m·deg).

This wire is in addition to high heat resistance, remarkable high specific resistance of 1.1 Омхмм2/m, which allows its use for heating elements, designed for continuous operation at t° up to 1100 °C — rheostats, resistors, heating elements of furnaces. Very often it is used in the manufacture of welded structures operating in aggressive environment. It is demanded in chemical, pulp and paper, gas, petrochemical industry. Without it, hard to do in the aircraft industry in the manufacture of paint products, fertilizers. It is demanded in the manufacture of parts of combustion chambers, and the various instruments, where important heat resistance, reliability and durability. Wire KHN78T applicable for welding of Nickel-chromium alloys and metal constructions from carbon steel.
