Grain-oriented electrical steel sheet and strip, also known as CRGO (Cold-Rolled Grain-Oriented) steel, are essential materials in the production of transformers and large electrical machines. These specialized sheets feature a grain structure optimized to enhance magnetic properties in a specific direction. This design significantly reduces energy losses and boosts efficiency. CRGO steel stands out for its high magnetic permeability and low core loss, making it the preferred choice for applications that demand superior magnetic flux conduction. By minimizing energy wastage and enhancing the performance and reliability of electrical devices, CRGO steel is a crucial component in the energy sector.

INDIAN STANDARD IS 3024:2015

As of February 5, 2024, the latest Quality Control Order (QCO) issued by the Ministry of Steel, Government of India mandates that Grain Oriented Electrical Steel Sheet & Strip (CRGO) must comply with the Indian Standard IS 3024:2015. This standard outlines the essential requirements for CRGO materials used in the cores of electrical transformers and other electromagnetic devices. Compliance with IS 3024:2015 guarantees that CRGO sheets and strips meet crucial quality standards, including magnetic flux density, core loss, and thickness tolerance. This adherence ensures optimal performance and efficiency in electrical applications. Compliance with this standard is vital for manufacturers to guarantee product consistency, reliability, and adherence to regulatory requirements, thereby enhancing the efficiency and performance of electrical infrastructure.
