1. Market Background

In Iraq’s oil & gas and construction machinery industries, shafts, gears and valve components operate under heavy loads, dust and impact. These harsh conditions cause rapid wear and expensive downtime. Simply upgrading to more expensive materials is costly and increases machining difficulty. Using a nitriding furnace for surface nitriding, which hardens the surface while keeping a tough core, has become a key approach for local machining shops to improve reliability.

2. Customer & Application Scenario

The customer is a machining shop supplying spare parts for oil & gas equipment and construction machinery. The working environment is severe and parts are replaced frequently. Previously, they mainly used quenching and tempering: the hardness was acceptable, but surface fatigue and wear were still too high. They needed a stable 60 kW nitriding furnace to treat shafts, gears and other critical parts, extending service life and reducing unplanned downtime.

3. Our Solution (Product & Specifications)

Wuxi Wondery Industry Equipment provided a 60 kW nitriding furnace with:

• Power: 60 kW

• Process: multi-segment programmable nitriding curves

• Control: precise temperature control with recipe management

The nitriding furnace balances chamber size and power, enabling batch processing while maintaining good temperature uniformity. Considering Iraq’s unstable power grid, Wuxi Wondery strengthened the electrical system with over-/under-voltage and power-failure protection, so the nitriding furnace can shut down safely under abnormal conditions and avoid batch scrap.

4. Customer Feedback

The customer reported that, after introducing nitriding, wear on critical shafts and gears decreased noticeably, and replacement intervals were extended. Because the nitriding furnace operates at relatively low temperatures with minimal distortion, many parts require only slight straightening or no re-machining after treatment, reducing rework and scrap.
Operators found the graphical interface and recipe-based control easy to learn. In the customer’s view, this 60 kW nitriding furnace from Wuxi Wondery Industry Equipment offers a good balance of investment, energy consumption and reliability, and has become an important asset in upgrading their surface heat treatment capability.

5. Conclusion

For machining companies in Iraq and the wider Middle East, a well-configured nitriding furnace is an effective way to extend part life while keeping costs under control. The 60 kW nitriding furnace solution from Wuxi Wondery Industry Equipment integrates smoothly into existing lines and leaves room for future expansion into more advanced surface heat treatment processes.
