Advanced Heat Treat Corp. (AHT) has expanded induction hardening and gas nitriding capacity at its Cullman, Alabama facility, increasing throughput and enabling the processing of larger and more complex parts for manufacturers. The investment supports growing demand for surface hardening technologies used to improve wear resistance, fatigue strength, and durability across industrial applications.

The expansion includes two additional systems: a larger induction hardening unit capable of processing parts up to 60 inches in diameter and an additional gas nitriding unit to support high-volume nitriding programs while maintaining quick lead times and consistent processing quality. Earlier systems primarily handled cylindrical components such as shafts, gears, and pins. The new system can now accommodate more complex geometries, broadening the range of parts the plan can process.
“These investments allow us to scale with our [clients],” said Tim Garner, plant manager at AHT. “We are well-positioned to handle a wide range of part sizes, geometries, and production volumes without compromising turnaround times.”
