General characteristics

Steel brand KHN56VMKJU (ЭП109-VD) is high-temperature chromium-Nickel alloy. Composed of 52 — 62% Ni, about 8.5−10.5% Cr. As additives used silicon, manganese, tungsten, aluminum, molybdenum, titanium, cobalt, sulfur, boron. Temperature for raskopki semis = 1170° at the beginning of the process and about 850° — in the very end, after forging, the products are cooled in the air. This type of steel refers to a hard base, to obtain compounds of high quality necessary pre-heating of parts to temperature of 200−300°C with additional heat treatment — annealing after welding. Fastening parts and subassemblies is performed by means of manual arc welding electrodes KTI-762. The final heat treatment is necessary in order to be able to remove welding stress.

Production

KHN56VMKJU alloy steel allows to manufacture hot rolled seamless pipes, warm, cold. Used in the construction of industrial pipelines for discharging hot gases, installation of heating systems. Pipe with respect to the accuracy of manufacture can be produced normal and high precision. Designed for stable operation at a temperature of about 650 °C. They are also used for the production of discs, rotors operating in the difficult conditions of petrochemical engineering. Quality alloy allows us to produce products that can withstand in some situations, the load at temperatures up to 850 °C. Such a tube may be included in the layout of drainage systems. In accordance with the wishes of the customer it can be with different kinds of thread. Thread sizes, assortment of pipes normalized GOST requirements. The tube can be made dimensional with a length of 4−12 m, with variable and multiple dimensional length. In the latter case, for each cut the stock to produce 5 mm, and the longitudinal deviation of the size in length must not exceed 10 mm. Welded tubes can be welded round and shaped with rectangular, oval or square cross-section.

Application

Pipe and round steel KHN56VMKJU are the most popular rental products. The leaves of this steel are used as components of high temperature installations, the petrochemical industry and engineering. Prolonged service of the products is limited by limiting t° 850 °C. At a temperature> 850° begins to rapidly form slag. This steel is used for the production of discs, fasteners, flat springs which can do the job in difficult conditions.
