CRGO material has the least figure of maximum core loss in the rolling direction. With the increased shearing angle to the rolling direction, the core loss at any particular flux density goes up and becomes generally highest in the transverse direction. Because of this, it is possible to use CRGO in static electrical machines which include all types of power transformers, distribution transformers, etc.
Manufacturing Mills of CRGO Steel do guarantee the core loss figure at a flux density of 1.5 Tesla for conventional grain-oriented steel and at 1.7 Tesla in case of HI-B and HI-B-LS steel. The grades of material popularly used are M-3, M-4, M-5 and M-6. We also use, for special requirements of the customers, HI-B Material designated as MOH, TRAN-COR H, ZH, ZDKH and ZDMH.
