Heavy Engineering & Earthmoving – Applications of Steel Bright Bars
This application falls under the Automotive, Agri & Heavy Machinery segment, where bright steel bars are
used for high-load, shock-resistant and fatigue-critical components.
In heavy engineering and earthmoving equipment, bright bars are preferred for their strength,
straightness, dimensional consistency and predictable performance under extreme operating conditions.

FAQs
Why are bright bars preferred for earthmoving equipment?
Bright bars offer better fatigue performance, dimensional accuracy and surface integrity compared to hot rolled bars.
Which grades are suitable for boom pins and pivot pins?
EN19, 42CrMo4 and EN24 are commonly used depending on load, wear and heat treatment requirements.
Can bright bars handle shock and cyclic loads?
Yes. Properly selected and heat-treated bright bars perform reliably under shock, vibration and repeated loading.
