Sheet, strip KHN45JU - ЭП747
KHN45JU sheet, strip, foil — products of heat-resistant steel used for the manufacture of parts slot furnaces, grids, furnace conveyors, parts of burners, covers thermocouples and other parts operating at t° to 1300 °C. the Main components of the brand KHN45JU are iron, Nickel and chromium. The proportion of iron amounts to 38.1%, Nickel — 44−46%, chromium — 15−17%. In the fourth position — aluminium (2,9−3,9%), Also the alloy contains manganese and silicon (1%), phosphorus (up to 0,025%), selenium (up to 0,03%), less than 0.1% barium and carbon.
The percentage composition of (GOST 5632−72)
Smelting alloy KHN45JU occurs in open electric furnaces in accordance with GOST 5632−72. Forging rental starts at 1150−1180°C and finishes at a temperature below 850 °C. the Sheet after rolling is hardened at a temperature 1060−1100°C in water, under a water shower or air. The tape is quenched in air at 1100 °C. the Sheet and tape welded all types of welding. For manual arc welding using electrodes OzL-35 and OzL-35. KHN45JU sheet manufactured according to the specified GOST 24 982−81 specifications. This standard applies to cold-rolled and hot-rolled steel heat-resistant alloys on Nickel and iron-based smelted in an open way. Rolled sheet of heat-resistant steel may have a thickness from 1 mm — depending on the conditions of use of the products. Sheet, strip, foil are sorted according to accuracy of rolling, the nature of edges and flatness. Flatness can be a singular, high, improved and normal. Accuracy — normal and high. Edge — cut and uncut.

From the production of tableware and Cutlery to heavy engineering, chemical and medical industries. Products made of heat-resistant alloys are needed especially in those industries that require materials with good resistance to thermal load, such as in the construction of engines, turbines, different furnaces, combustion chambers and heating equipment. Heat resistant sheet manufactured parts and designs for objects of missile and space defense. The high content of chromium and Nickel products can withstand temperatures of over 1000 °C, do not lose their high resistance to acidic and corrosive environments.
