Steel and Iron - Carbon steel cast billet ingots, billets, blooms and slabs for re-rolling into structural steel (ordinary quality) – Specification
Summry
Carbon steel cast ingots, billets, blooms, and slabs are semi-finished steel products manufactured for re-rolling into structural steel of ordinary quality. They serve as basic raw materials for producing beams, angles, channels, and other structural sections used in construction and general engineering applications.
Why BIS Certificate is Mandatory for Carbon steel cast billet ingots, billets, blooms and slabs for re-rolling into structural steel ?
BIS certification is mandatory to ensure that carbon steel cast billets, ingots, blooms, and slabs meet Indian Standards for chemical composition, internal soundness, and mechanical properties. Certification prevents the circulation of substandard steel, ensures safety of structural products, and supports quality consistency in construction materials.
What is BIS Certified for Carbon steel cast billet ingots, billets, blooms and slabs for re-rolling into structural steel ?
The BIS certified specification defines requirements for carbon steel cast semi-finished products intended for re-rolling into ordinary quality structural steel. It specifies limits for chemical composition, casting quality, freedom from defects, testing methods, marking, and inspection to ensure suitability for rolling and structural use.
