JGEF Furnace installed a series of nitrocarburizing furnaces at a commercial heat-treatment company’s recently opened 53,820-square-foot facility in Chongqing, China. The furnaces are designed to maintain temperature uniformity of ±3°C. The series of pit nitrocarburizing furnaces use software that controls the nitriding potential and maximizes the efficiency of the process. The systems are capable of maintaining the preset values of Kn, and the process requires no manual adjustments from start to finish.
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 an order for a turnkey nitrocarburizing system from Alu Menziken Extrusion AG, a Swiss manufacturer of aluminum profiles and complex extrusion-press products. The system, which incorporates Nitreg-C technology for treating aluminum extrusion dies, was installed at the company’s new state-of-the-art manufacturing facility in northwestern Romania. The pit furnace has overall chamber dimensions of 31.5 inches in diameter x 59 inches high (800 x 1500 mm) with capacity optimized to nitrocarburize a 3,300-pound (1,500-kg) load. The process technology adapts to the application requirements to deliver improved performance of extrusion dies.
Advanced Heat Treat Corp. (AHT) broke ground on a 15,000-square-foot expansion at its corporate headquarters in Waterloo, Iowa. The addition will allow AHT to segregate its trademark processes, UltraGlow ion nitriding/nitrocarburizing and UltraOx (gaseous ferritic nitriding/nitrocarburizing and oxidation treatments). The expansion will also include two new gaseous ferritic nitriding/nitrocarburizing units with sizes up to 13 feet tall and 5 feet wide.
Last but certainly not least, as the saying goes, is our discussion of gas nitriding and nitrocarburizing process simulators and how they are used to predict and control these case-hardening processes. Let's learn more.
A case-hardening technique in use since the early 20th century, nitriding has been an effective lower-temperature heat treatment for steel workpieces since even before engineers and metallurgists fully understood it.
