Summry

These are stainless steels specially designed for cold heading and cold extrusion processes. They provide excellent corrosion resistance, high strength, and good ductility, making them suitable for precision fasteners, bolts, screws, and industrial components. Their controlled microstructure ensures reliable performance under high plastic deformation at room temperature.

Why BIS Certificate is Mandatory for Steels for cold heading/cold extrusion applications – specification Part 2 Stainless steel ?

BIS certification is mandatory to ensure stainless steels meet Indian Standards for chemical composition, corrosion resistance, and mechanical properties. It prevents the use of substandard materials, ensures consistent quality, improves safety of finished components, and guarantees reliability in automotive, aerospace, and precision engineering applications.

What is BIS Certified for Steels for cold heading/cold extrusion applications – specification Part 2 Stainless steel ?

The BIS certified specification defines stainless steels suitable for cold heading and extrusion, detailing chemical composition limits, mechanical properties, corrosion resistance, surface quality, and testing methods. Compliance ensures steels can withstand cold working, produce defect-free components, and maintain uniformity, safety, and durability across all industrial and manufacturing applications.
