Nitrex Metal Inc. completed the installation of a new nitriding/nitrocarburizing system at Korean heat treater Dongwoo HST Ltd. The system will be used primarily for processing Hyundai ring gears and includes three Nitreg®-based nitriding technologies for a number of steel types with process recipes for each product application. The Nitrex furnace at the Dangjin site has a work zone of 39 inches in diameter x 98 inches high and a gross load capacity of 6,600 pounds. In addition to the ring-gear business, another impetus for the purchase is for Dongwoo HST to meet the country's growing demand for advanced heat treatments.
