urrently, nitriding is carried out predominantly in pit type vertical furnaces with metal alloy retorts to hold the work load during the nitriding cycle. The large thermal mass of these furnaces requires long heat-up and cool-down times. Another factor is that the ammonia nitriding gas cracks not only on the work load but on the.

Experienced SECO/WARWICK process specialists can assist in furnace type selection and in product material handling/loading. The SECO/WARWICK R&D facilities help customers in determining the correct cycle for their products. Optional tools such as a simulation and database programs for many common alloys and
Nitrex Metal has created a worldwide network of independent licensees (commercial heat treaters) using its Nitreg? gas nitriding technology, and has sold gas nitriding furnaces, control systems with process control software, to even more in-house users. In addition, many heat treating furnaces and control systems have
Single-chamber vacuum furnace with ZeroFlow? for regulated gas nitriding of machine parts, vehicles, aircraft and tools. SECO's vacuum nitriding furnaces achieve optimum results by using uniform high convection heating, precision nitriding potential and ammonia control, along with advanced load mechanics to
