Production
This steel is melted in an open type induction furnace. The hot deformation temperature of the rolled steel is 1000 °C at the beginning of the process and 750 °C at the end of the process. The steel is cooled after deformation. The first cooling is done in water, oil or air, or the other cooling is done with water, followed by holding the product for 4-4.5 hours. The bars are hot-rolled and calibrated to give the exact outer diameter. Welding is carried out using KTI-762 electrodes.
Use
Various semi-finished products are made of this heat resistant alloy. The most popular of them are pipes, circles and bars. They are used in the power engineering industry in the manufacture of a variety of equipment, fasteners, valves, motor parts, fragments of pipelines, continuously operating at t ° up to 650 ° C. Intense scale formation begins above 850 °C.
