Heat Treatments, a leading provider of commercial heat treatment services in New Zealand and one of Nitrex’s earliest customers, has recently expanded its operations by adding another Nitrex nitrocarburizing system.

This marks a significant milestone in the company’s long-standing partnership with Nitrex, which dates to 1992 when Heat Treatments purchased its first Nitrex system with Nitreg® nitriding capabilities. As operations grew, the company later added a second system in 2004 for nitrocarburizing and post-oxidation treatments. Contrary to the first two systems, which are identical pit furnaces, the latest addition, an NXK series, features the furnace and control panel mounted on an integral platform. Delivery, installation, and startup time and costs are reduced with this design. The NXK-812 model is designed to treat workloads weighing up to 1,200 kg, with a diameter of 800 mm (31.5″) and a height of 1200 mm (47.25″). The system is equipped with advanced process technologies, including Nitreg®-C controlled nitrocarburizing and ONC® post-oxidation, which provide precise control and consistent results.

“We are proud to continue our partnership with Heat Treatments, who has been a true ambassador of the Nitreg® brand in New Zealand,” said Nikola Dzepina, Nitrex Account Executive. “With prior installations in operation between 20-30 years, our systems are a testament to their durability and reliability. We are confident that this latest Nitrex system will help Heat Treatments continue its growth and success, and we look forward to supporting the company in the future.”

Heat Treatments is capable of nitrocarburizing a variety of materials and applications, including but not limited to alloy steels, tool steels, high-speed steels for aluminum extrusion dies, and deep case nitrocarburizing for general applications. The system was successfully commissioned in the first quarter of 2023.
