Mechanical springs are vital components across various industries, including automotive and aerospace, and their performance depends significantly on the quality of the steel wire used in their production. To ensure the safety and reliability of these essential components, the Bureau of Indian Standards (BIS) has set rigorous guidelines under IS 4454 (Part 2): 2001.

IS 4454 (Part 2): 2001 specifically outlines the requirements for oil-hardened and tempered steel wire used in manufacturing mechanical springs. The oil hardening and tempering processes are crucial heat treatments that enhance the steel wire's strength, resilience, and durability, making it ideal for high-stress and fatigue-resistant applications.

In India, compliance with IS 4454 (Part 2): 2001 is essential for manufacturers and suppliers of oil-hardened and tempered steel wire for mechanical springs. This standard addresses key aspects such as chemical composition, mechanical properties, surface quality, and dimensional tolerances, ensuring the steel wire meets rigorous quality and performance criteria.

To achieve BIS certification, manufacturers must have their steel wire products undergo a thorough series of tests performed by accredited laboratories. These tests ensure that the products meet the rigorous standards specified in IS 4454 (Part 2): 2001.
