IS 11169 (Part 1): 2022 Steels for Cold Heading Cold Extrusion Applications

IS 11169 (Part 1): 2022 has requirements for wrought carbon and low alloy steels. These materials are used in the cold heading and cold extrusions. The standard determines the quality and performance of steel products, thereby being fundamentally relevant in the production processes of the respective products that demand incredible strength and durability.

In addition, specifications are provided for the selection of material, processing, testing, limits of chemical composition, and the requirements of mechanical properties. Conformity with IS 11169 allows manufacturers to manufacture reliable and efficient steel products. This standard is mandatory in car industries, building, construction, and machinery whose industrial operations need stronger materials. These specifications offer scope to upgrade product quality in the industry.

What is Steel for cold heading and extrusion? 

Steels for cold heading and extrusion are special materials for manufacturing components such as fasteners and bolts. These steels are, above all, wrought carbon and low alloyed, and they have received broad acceptance for their exceptional strength and ductility properties that enable them to be shaped at room temperature without crack formation. The procedures are about forming the steels into specific shapes needed in producing any important commodity from car components to constructions. Compliance with standards such as IS 11169 (Part 1): 2022 ensures the quality and performance of demanding applications.

This standard specifies the requirements of unalloyed and alloyed steels in cold heading and in cold extrusion. It defines different dimensions of bars, wire rods, and wires in the range of 2 mm up to 100 mm.

The paper deals with three classes of steels:

• Steels not intended for heat treatment.
• Case hardening steels.
• Quenched and tempered steels.

The standard cannot, however, be used for cold-headed or cold extruded properties of parts.

For this document, the terms and definitions given in IS 1956 Parts 1, 2, and 3 shall apply.
