Steels for Cold Heading/Cold extrusion application Part-1 Wrought carbon and low alloy steels
Summry
Steels for cold heading and cold extrusion are specially manufactured wrought carbon and low alloy steels designed to withstand severe plastic deformation at room temperature. These steels offer excellent ductility, uniform microstructure, and controlled chemistry, making them suitable for fasteners, bolts, screws, and precision-engineered components.
Why BIS Certificate is Mandatory for Steels for Cold Heading/Cold extrusion application Part-1 Wrought carbon and low alloy steels ?
BIS certification is mandatory to ensure that cold heading and cold extrusion steels meet Indian Standards for chemical composition, mechanical properties, and workability. Certification prevents the use of inferior steel, ensures product safety, maintains consistency in industrial applications, and supports quality assurance in critical automotive and engineering components.
What is BIS Certified for Steels for Cold Heading/Cold extrusion application Part-1 Wrought carbon and low alloy steels ?
The BIS certified specification defines requirements for wrought carbon and low alloy steels used in cold heading and cold extrusion applications. It covers chemical composition limits, mechanical properties, surface quality, internal soundness, testing methods, and inspection criteria to ensure steels perform reliably during high-deformation forming processes.
