Nano-STM Technology - Nitriding Stainless Steels
Stainless steels have excellent corrosion resistance but possess relatively low strength and wear resistance. NANO-S
TM can now expand their application range to include components that are subjected to intensive wear.

Effluent Neutralizing System - Standard INS Series
Highly recommended for gas nitriding / nitrocarburizing furnaces using ammonia gas, the Nitrex line of high temperature neutralizers is designed to eliminate residual ammonia and/or other pollutant gases while minimizing NOX emissions.

Multi-Chamber Flow-Through Nitriding/Nitrocarburizing Furnaces NXH Series
The NXH series is a modular, multi-chamber flow-through line of nitriding/ nitrocarburizing furnaces. These furnaces incorporate a computer control system, process software and control technology known as NITREG®. They are designed to operate in a completely automatic manner without the need of specialized personnel. All the stages of the heat treating process such as pre-oxidation, pre-heating, purging, nitriding/nitrocarburizing, and cooling are accomplished in one uninterrupted cycle as the loads are automatically transferred from chamber to chamber.

Compact Nitriding/Nitrocarburizing Furnaces NX-400 Series
The multipurpose NX-400 series of nitriding / nitrocarburizing systems is an economical and dependable choice for use in small scale processing as well as for general laboratory/testing purposes.

Nitrex Completes Two New Nitriding Installations for DANA Group

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 with the new Nitrex system 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. In addition to the new installation, Nitrex concurrently upgraded the operating software of the original nitriding system with NPC and NPM; the first is the newest version of the Nitrex Process and Furnace Control Program, the latter is a software utility that links the control system to a central interface at a remote location.
