Steel and Iron - Stock for Forgings produced from Continuously Cast Blooms, Billets and Slabs
Summry
Stock for forgings produced from continuously cast blooms, billets, and slabs refers to semi-finished steel products used as raw material for forging operations. These materials provide uniform internal structure, good mechanical properties, and reliable workability for manufacturing automotive, engineering, and industrial forged components.
Why BIS Certificate is Mandatory for Stock for Forgings produced from Continuously Cast Blooms, Billets and Slabs ?
BIS certification is mandatory to ensure forging stock meets Indian Standards for chemical composition, cleanliness, internal soundness, and mechanical properties. It prevents defects such as cracks or inclusions in forged parts, ensures safety in critical applications, and supports quality consistency across the forging industry.
What is BIS Certified for Stock for Forgings produced from Continuously Cast Blooms, Billets and Slabs ?
The BIS certified specification defines requirements for continuously cast steel blooms, billets, and slabs intended for forgings. It covers chemical composition limits, dimensional tolerances, surface quality, internal soundness, testing methods, inspection, and marking to ensure suitability for forging operations.
