- Hot Cold Rolled Steel Strips which are used as materials in electrical steel processing, are the basic material used in transformer cores, motors, and generators where magnetic efficiency is of prime importance.
- Hot-rolled steel strips are mainly used as material for further cold rolling and annealing, whereas cold-rolled steel strips have improved thickness tolerance and surface finish properties suitable for use in electrical applications.
- A uniform chemical composition and dimension accuracy in the produced steel strips can significantly influence the core loss, efficiency, and reliability of electrical appliances.
- In India, steel strips intended for electrical steel products need to be in line with the standards of IS:18316:2023.
- Any manufacturer or importing company providing such steel strips must have a BIS certification to ensure that all supplied electrical steels are of the same quality.
Introduction | IS 18316:2023
IS 18316:2023 is a Bureau of Indian Standards that outlines the quality and technical specifications for Hot & Cold Rolled Steel Strips used during the processing of electrical steel. These steel strips are the primary material used to produce electrical steel, an important component used in the construction of transformer cores, motors, and generators, as well as other energy-efficient electrical appliances. The need to develop this Indian standard arises due to the importance of having a consistent chemical composition, size, and surface finish quality among Hot Cold Rolled Steel Strips, as even the slightest difference between them can highly affect the magnetic properties and efficiency loss of electrical steel. In India, with the increased importance being placed on efficient use of power and maintaining the stability of the power supply, it has now become an important requirement to adhere to IS 18316:2023.
What is IS 18316:2023?
The Indian standard IS 18316:2023 Hot Cold Rolled Steel Strips regulates the supply of hot rolled and cold rolled strips of steel for processing in electrical steel in the country. This Indian standard promotes energy efficiency by ensuring the selection of only quality-compliant strips of steel for the electrical steel supply chain. The implementation of this Indian standard is mandatory and requires BIS certification for the supply ofHot Cold Rolled Steel Stripsfor the electrical application.
Key points
- IS 18316:2023” standardizes the hot rolled and cold rolled steel strips that are used in electrical steel products. This is a standard that defines the quality of steel that is used in making transformers, motors, and generators.
- Critical parameters of composition, size tolerance, and surface finish are specified by the standard and have a direct effect on magnetic properties and energy losses.
- Compliance with the IS specification, IS 18316:2023, becomes mandatory along with BIS certification, which makes importing and manufacturing Hot Cold Rolled Steel Strips for use in electrical purposes compulsory for the Indian market.
- With input material control, IS 18316:2023 helps promote energy efficiency and a reliable energy supply within India’s electrical power sector.
Why is BIS Certification Mandatory?
BIS certification is an essential requirement for assuring that products (Electrical Steel Processing )that are critical for public safety, energy efficiency, and infrastructure adhere to a certain standard of quality. When it comes to Hot Cold Rolled Steel Strips used for electric applications, an essential BIS certification ensures that sub-standard products cannot find entry into a particular market while also working towards Indian regulation and efficiency.
Key points
- Ensures consistency in quality and safety Being mandatory, BIS certification also ensures that products conform to Indian Standards in order to avoid any danger of defects or failure in their use.
- Protects national infrastructure and end-users Industries such as energy and electrical products may suffer from inefficient usage of energy and failures if the products have low-quality components, which BIS certification safeguards against.
- Forms a Legal Basis for Enforcing Compliance BIS certification makes quality compliance compulsory, not voluntary, and thus the regulatory authority can act against the manufacturer or importer who doesn’t meet the quality standards.
- Encourages trust and fair play in the market The certified products have a level playing field where the inferior or unevaluated products cannot price the compliant ones out of the market.
