Nitrex Metal Inc. supplied a nitriding system to Hydro Extruded Solutions in Trzcianka, Poland, to address the company’s need for improved process performance and more accurate control of nitriding results. The nitriding system replaces a decommissioned nitrider that was phased out several years ago due to extrusion die failures and inconsistent metallurgical results. It includes Nitreg technology that helps optimize parameters for maximum efficiency and quality and increase die strength and extrusion throughput while reducing the possibility of potential die failures.

Family-owned heat-treatment company GalvanoTechnik of Lombardy, Italy, expanded its portfolio to include Nitreg-controlled nitriding, Nitreg-C nitrocarburizing and ONC in-process oxidation treatments. The company invested in a compact Nitrex system configured to process 23.5-inch-diameter x 35.5-inch-high workloads that weigh up to 1,300 pounds. The system complies with the temperature-uniformity requirements of AMS 2750E and meets the specifications of ASM 2759/10, which make it possible to consistently achieve the required metallurgical and mechanical properties for controlled nitriding.

Nitrex Metal received a contract from Qatar Aluminum Extrusion Company (Qalex) for the supply and installation of an NX-1015 potential-controlled gas nitriding system. The system is configured for treating various-sized flat and hollow dies used in the production of aluminum extruded profiles for the construction and transportation markets. The NX-1015 furnace has a load capacity of 4,400 pounds (2,000 kg). While this is slightly larger than current production needs, the additional capacity will accommodate future growth when Qalex adds a second extrusion press.
