Steel and Iron - Carbon Steel Cast Billet Ingots, Billets, Blooms and Slabs for Rerolling purposes- Specification
Summry
These are semi-finished carbon steel products used as raw material for rerolling into rods, bars, and structural sections. Cast ingots, billets, blooms, and slabs are produced in controlled shapes and sizes to ensure uniform chemical composition and mechanical properties, suitable for downstream steel rolling and fabrication processes.
Why BIS Certificate is Mandatory for Carbon Steel Cast Billet Ingots, Billets, Blooms and Slabs for Rerolling purposes ?
BIS certification is mandatory to ensure that carbon steel billets, blooms, and slabs conform to Indian Standards for chemical composition, mechanical strength, and dimensions. Certification prevents substandard steel supply, ensures consistent quality, enhances industrial safety, and guarantees reliable performance during rerolling and in finished structural or engineering products.
What is BIS Certified for Carbon Steel Cast Billet Ingots, Billets, Blooms and Slabs for Rerolling purposes ?
The BIS certified specification defines chemical composition limits, mechanical properties, surface quality, and dimensional tolerances for cast carbon steel ingots, billets, blooms, and slabs. It includes testing procedures for tensile strength, hardness, and internal soundness to ensure steels are suitable for rerolling into high-quality structural and engineering products.
