Description
The HN77TYuR brand is a hot strength alloy on a nickel basis. HN77TYuR steel range. HN77TYuR steel should correspond: hot-rolled round – GOST 2590-88; hot-rolled square – GOST 2591-88, OST 14-2-205-87, the branch standard of Minchermet of the Russian Federation; shod round and square – GOST 1133-71; hot-rolled and shod strip – GOST 4405-75; hot-rolled strip – GOST 103-76; hot-rolled hexagon – GOST 2879-88; the calibrated round – GOST 7417-75; the calibrated square – GOST 8559-75; the calibrated hexagon – GOST 8560-78; with special finishing of a surface – GOST 14955-77. Chemical composition of the material HN77TYuR in %: Fe to 4; With to 0,07; Si to 0,6; Mn to 0,4; Ni 69,078 – 78; S to 0,007; P to 0,015; Cr 19 – 22; Ce to 0,02; Ti 2,4 - 2,8; Al 0,6 – 1; B to 0,01. Properties of HN77TYuR steel: Specific density: 8200 kg/m3 Heat treatment: Tempering of 1080 - 1120oC, Cooling water, Ageing 750oC, 5 h, Forging temperature, °C: beginnings 1180, end 900. Section to 300 mm is cooled on air the Hardness of material: HB 10-1 = 255 - 321 MPas Workability cutting: in the thermoprocessed state at HB 262 and σв = 1060 MPas, To υ TV. spl = 0,20, Kυ B. St = 0,08 Bondability of material: hardly welded. Hot strength alloy on the basis of HN77TYuR nickel possesses difficult chemical structure. It includes 12 — 13 components which are carefully balanced for obtaining necessary properties. Content of such impurity as silicon, phosphorus, sulfur, oxygen and nitrogen is also controlled. The maintenance of such elements as selenium, tellurium, lead and bismuth should be insignificant small that is provided with selection of blend materials with the low maintenance of these elements since it is not possible to get rid of them in a progress of a heat. HN77TYuR steel application: for hot-rolled bars, a cold-rolled tape, disks, rings, blades of the turbines and other parts working at temperatures up to +750 °C, the spring wire intended for production of cylindrical compression springs and stretching with a working temperature from -253 °C to +500 °C in different environments (air, vapors of sea water to +200 °C, vacuum) and the turbines used in consolidations, locking valves, heaters, control devices of reactors.
