The newly developed non-granular electrical steel is intended for use in electric motors, generators, low-power transformers, and rotors of hybrid and electric vehicles, boosting the country's productivity. confidence in the production of specialized steel products.
Technical details of the new electrical steelBSP has successfully produced about 1,100 tons of IS 18316 LS grade electrical steel with a thickness of 0.5 mm in its steelmaking workshop-II using a specially developed composition. This process is characterized by a low carbon content to increase ductility and a high silicon content to improve magnetic properties.The slabs were rolled to a thickness of 2.8 mm and a width of 1280 mm on a hot rolling mill, and then subjected to cold rolling to 0.5 mm on a cold rolling mill-3, which ensured accuracy, smooth surface and uniformity of magnetic properties. With magnetic uniformity in all directions, steel provides efficient energy conversion and reduced power loss.
Development of 28MnB5 steel for agricultural machinery
Along with electrical grade steel, BSP has developed boron-manganese steel 28MnB5, the first in India, specifically for agricultural machinery and wear-resistant components.This steel combines high strength, hardness, and wear resistance, achieved through a balanced metallurgical blend of medium carbon, manganese, boron, and chromium. It is suitable for the production of ploughshares, cultivator blades, disc harrows, shovels, excavators and claws, which are vital for heavy agricultural work.
SAIL's innovations in Bokaro mark an important step towards import substitution and expansion of domestic capabilities in specialized steel segments. The new varieties are expected to contribute to the development of energy-efficient technologies in India and the sustainable production of agricultural equipment.
