- The approval allows the plant to expand its production of High Strength Low Alloy (HSLA) cold-rolled steel, enhancing its portfolio of high-value products.
About Inclusion of New Steel Grades:
Certification Expansion: Earlier, the BIS certification covered steel grades only up to ISC 410. With the latest approval, the new grades are included under IS 513 (Part 2), ensuring compliance with nationally recognised quality standards.
Significance: It will improve product credibility and expand applications across sectors such as infrastructure, engineering, and manufacturing.
Special Electrical Steel: The plant also produced about 1,100 tonnes of 0.5 millimeter (mm) thick IS 18316 LS Grade Non-Grain Oriented (NGO) Electrical Steel for the first time, which is used in electric motors, generators, transformers, and hybrid or electric vehicle rotors to support energy-efficient technologies.
