BIS for IS 11169 (Part 1): 2022 Steels for Cold Heading/Cold Extrusion Application

Wrought carbon and low alloy steels are used in cold heading and cold extrusion plays a key role in manufacturing high-strength components. These steels are commonly processed at room temperature into fasteners, automotive parts, machine components, and various industrial products. The ability to withstand deformation without cracking makes the alloy steel suitable for large-scale production applications. They are designed to perform efficiently under high deformation without losing structural integrity.

To regulate quality and ensure uniform performance, the Bureau of Indian Standards has established requirements under IS 11169 (Part 1): 2022. The standard sets key requirements covering chemical compositions, strength and ductility properties, surface condition, size accuracy, and overall performance of the product during the cold extrusion process. This standard ensures that the steel meets the necessary safety and performance expectations for industrial use.

what is is 11169 (Part 1):2022

This is the Indian Standard for low-alloy steels used in cold extrusion applications, which defines requirements for mechanical properties and surface quality of the steel. This standard is set by the BIS (Bureau of Indian Standards) to ensure that product quality and safety are met, and the alloy steel is

The certification guarantees that steel products meet critical quality parameters such as hardenability, tensile strength, hardness, and surface quality. It also guarantees that the steel products are capable of withstanding deformation during cold forming processes without failure. BIS certification is a mandatory requirement for all manufacturers who produce wrought carbon and low alloy steels that are suitable for cold heading and cold extrusion. In addition to complying with the regulatory standards of India, a BIS license enhances customer trust in the quality of the wrought carbon and alloy steel. Manufacturers can rely on EVTL India to simplify and manage the BIS certification process efficiently. They offer support in documentation, application submission, and testing coordination for the carbon and alloy steel used for cold heading /extrusion.
