Nitrex Metal supplied three supersized nitriding systems to U.S. commercial heat treater Nitrex Inc., which recently completed phase one of a 12,000-square-foot expansion at its facility in Aurora, Ill. The project has increased the plant’s nitriding capacities to accommodate parts up to 177 inches (4.5 meters) long and loads of up to 25,000 pounds (11,300 kg). All systems are equipped with NITREG nitriding/nitrocarburizing technology, making it possible to meet AMS 2759/10 specifications for nitriding and AMS 2759/12 specifications for ferritic nitrocarburizing. The expansion also included upgrades to the company’s metallurgical laboratory.
