Nitrex Metal entered into an exclusive agreement with Voestalpine AG to bring new innovations in stainless steel hardening technologies to the Czech Republic. As a result of the agreement, Voestalpine added a nitriding system configured to process workloads 31.5 inches in diameter x 78.75 inches high (800 mm x 2,000 mm) that weigh up to 3,850 pounds (1,750 kg). The system complements a previously installed Nitrex system that combined Nitreg-C gas nitrocarburizing technology with ONC post-oxidizing technology for processing firearms.
Just as we’ve done in the past with other topics, Industrial Heating will take a look at the most-viewed Vacuum/Surface Treating articles (in terms of page views) on our website. Data was collected for 12 months, from August 2018 to August 2019.
The surface treatment of H13 hot-work tool steel for extrusion and forging dies is a technique that has been practiced for many years to extend the performance of the die surface. Many different methods of surface treatment have been tried with varying degrees of success.
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.
Advanced Heat Treat Corp. (AHT) announced building expansions at its Monroe, Mich., and Waterloo, Iowa, locations. The extra space will enable AHT to add more equipment and services. The Michigan site is expanding its pit, which will allow for two additional nitriding units. AHT Burton, referred to by the street name because there are two locations in Waterloo, is adding additional square footage onto its building. The expansion will allow for additional equipment and services to be added. The expansions are expected to be complete by mid-summer.
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.
Lindberg/MPH shipped a 2012°F (1100°C) crucible furnace to a research-and-development laboratory in the nuclear industry. The furnace will be used for laboratory melting applications including annealing, ashing, carbon firing, ceramic firing, hardening, nitriding, normalizing, sintering, solution treating and stress relieving. It is designed for use with a variety of crucibles, including alumina, mullite, quartz and metallic.
