This steel smelted in an induction furnace open. The temperature of hot deformation of rolled 1000 °C at the beginning of the process and 750 °C for its completion. Steel after deformation cooled. In accordance with the first mode is cooled in water, oil or air, or another cooling mode is performed with water, followed by aging products for 4−4. 5 hours. Rod produced hot-rolled method and by using calibration — to make products precise outer diameter. Welding is carried out with the help of electrodes KTI-762.
This heat-resistant alloy produces a variety of products. The most popular are pipes, round, rod. They are used in the energy engineering industry in the manufacture of various equipment, fasteners, valves, parts of engines, parts of pipelines, long-working at t° to 650 °C. Intensive scale formation begins above 850 °C.
