ХН68ВКТЮ-VI, ЭП578-VI round, wire, tube, sheet, strip


Heatproof and resistant to the negative influence of corrosion processes of alloy ХН68ВКТЮ-VI has perfectly proved at work in fairly harsh conditions. Such a high material characteristics primarily due to its chemical composition, Central to which is a Nickel (about 68 percent). Additions in the form of chromium, tungsten, copper, titanium and aluminum contribute to stabilization of the structure of the material and increase its operating parameters.

Nickel base causes the appearance on the surface of semi-finished products of alloy of this type is dense oxide film in contact with atmospheric air. This coating very effectively protects the body products from further destruction, providing the materials resistance to corrosion. Like chrome significantly increases resistance of the alloy and alloying components increase the safe limit thermal effects. Resistance to the destructive influence of high-temperature operating mode is determined by the structure of the material and the strength of the bonds between the atoms. Therefore, Nickel-chromium alloys are characterized by their ability to easily carry a sufficiently high temperature without losing its operational parameters and ensuring a long reliable service of the whole complex of equipment. For example, pipe ХН68ВКТЮ-VI has perfectly proved at work in the temperature range from 1250 to 1300 degrees Celsius. And resistance to gas corrosion and considerable stress significantly expands the scope of the semifinished products of this type. Another important advantage is the significant electrical resistance (this parameter is very important for the electrical industry). To improve the performance properties, the alloy may be subjected to annealing (at temperatures up to 1200 degrees), in air environment, and with the use of water. Semi ruskovaara at a temperature from 1150 to 850 °C from the beginning to the end of the procedure.


Given the basic properties and operational parameters, the tube ХН68ВКТЮ-VI is actively used in the manufacture of various furnace equipment, especially annular furnaces involved in production cycle of ceramic products. Good resistance to dynamic influence of the gas flow allows the use of such intermediates in the manufacture of turbine equipment of aircraft engines. Tubular products can serve as a reliable protection for thermocouples of various designs and purposes, when used for operation in particularly aggressive industrial environments. High electrical resistivity makes the whole product range of the brand ХН68ВКТЮ-VI highly relevant material for the needs of the electrical industry. This alloy is used in the production of heating equipment, household products, and in the manufacture of large industrial units. It is particularly noteworthy not only many useful properties and attractive appearance of products from chromium-Nickel raw materials. This quality has found its application in the manufacture of fireplace and furnace equipment. The chimney of the materials of this type are not only able to withstand significant temperature changes, but does not require additional coating, keeping its original appearance even after prolonged use.


Our site offers a wide range of products from chromium-Nickel alloys. High quality of products and lack of intermediaries determine the most favorable conditions for purchase of products of alloy 03KHN28MDT to solve any production problems. Delivery in the shortest possible time in any region of the country and abroad, compliance with regulatory documentation already gained the trust of regular customers. Thanks to an acceptable cost and wide model range of semi-finished products Nickel-chromium alloys, and enjoy continued popularity in all spheres of production.
