Nitrex Metal Inc. ( completed the start-up of a 6000-kg capacity nitriding system for processing ring gears at Dana in Arco, Italy, a facility that manufactures transmission boxes for off-road equipment. This project reflects an interesting technological shift from induction hardening to a lower-cost, high performance Nitreg® controlled nitriding process. Production started in May 2006.

The piston ring facility of Dana Automotive Systems Group in Brazil has also increased the nitriding capacity at its Gravataí location earlier this year. The additional 1.5-ton nitriding furnace is engineered to use Nitreg®-S, a special controlled nitriding technology designed for stainless steel applications. Nitreg®-S ensures the uniformity of nitrided case with no distortion following the treatment. The turnkey system also included the integration of an IN-65 effluent neutralizer to meet environmental emissions requirements.

Nitrex Metal supplies automated, turnkey heat-treating systems for nitriding and nitrocarburizing applications and operates a network of commercial heat-treating facilities across North America. To date, the company has over 200 installations in plants worldwide.
