Stainless steel wire XH78T increased heat resistance has a complex composition of the nine key elements. Mark XH78T may be referred to as EI435. Foreign counterparts: 2.4951NiCr20Ti (Germany), GH3030 (China). Nickel base gives high ductility. This greatly facilitates the cold rolling. The main alloying elements forms a surface oxide film, which protects the wire from corrosion and easily restored in case of damage. At t ° 1100 ° C rate of surface oxidation is 0.2 mm. Chromium increases the chemical resistance, heat resistance, and titanium wire imparts structural strength and homogeneity.
Chemical composition with
Such expensive metals such as chromium, nickel, chromium, titanium alloy composed XH78T, affect its cost. However, high strength, reliability and durability of the belt, the possibility of recycling material — reduces the high cost of practically in long-term investments.
Properties at 20 ° C
Tensile strength of 880 MPa is reduced at 1100 ° C and 40 MPa. Yield does not exceed 300 MPa, the lowest — 98 MPa at t ° 800 ° C, after which the rate begins to increase. By 1100 ° C it increases to 105 MPa. Elongation at break — 40%. At 900 ° C the maximum level recorded 90% elongation. Specific gravity 8.38 g / cm³; modulus 1st kind 2.19 MPa; linear expansion coefficient of 12.2 [1 / deg]; The heat capacity of up to 14.6 W / (m · deg).

This wire except high heat resistance, remarkable significant resistivity 1.1 Omxmm2 / m, which allows to use it for heating elements, designed for long-term work at t ° to 1100 ° C — rheostats, resistors, heating elements of furnaces. Very often it is used in the manufacture of welded structures operating in aggressive environments. It is in demand in the chemical, pulp and paper, gas production, oil refining industry. Without it difficult to do in aircraft in the production of paints and varnishes, fertilizers. It is in demand in the manufacture of parts of the combustion chambers, and very different equipment, which are important for heat resistance and durability. Wire XH78T applicable for welding nickel-chromium alloys and metal structures made of carbon steel.
