Metallurgical Considerations and Process Requirements Nitriding is a ferritic thermochemical method of diffusing nascent nitrogen into the surface of steels and cast irons. This diffusion process is based on the solubility of nitrogen in iron, as shown in the iron-nitrogen equilibrium diagram (Fig. 1). 01_Nitriding.qxd 9/30/03 9:58 AM Page 1 Carburizing and nitriding - Vacuum FurnaceNitriding is the most widely used gas nitriding process with a heating temperature of 500-600 degrees centigrade. Nitrogen atoms and aluminum on the surface of the steel. The alloying elements commonly used in carburizing steels are manganese, chromium, nickel, molybdenum, tungsten, vanadium and boron.

Gas Nitriding Surface Hardening Process at Metlab of Gas nitriding is a surface hardening process, where nitrogen is added to the surface of steel parts using dissociated ammonia as the source. Gas nitriding develops a very hard case in a component at relatively low temperature, without the need for quenching. Huppert Industries, Inc. Chicago, Illinoisindustrial furnaces including the most reliable gas Nitriding pit furnace system on the market and high temperature furnaces capable or reaching temperatures up to 3100°F. Quality and reliability is the corner stone of every Huppert Industries heat-treating box furnace. For more information regarding our furnaces please call:708-339-2020.
After the cast is cooled it may require further heat treating in an industrial furnace to strengthen the metal. In addition to non-ferrous melting and holding equipment, Lindberg/MPH also supplies industrial furnaces to the foundry industry for heat treating applications.

Etched with a 10:1 mixture of 4% picral and 2% nital (1250X, oil immersion). The processing associated with nitriding does have some advantages in avoiding problems such as quench cracking Nitriding Furnace Heat Treat Furnace Lindberg/MPHNitriding Pit Furnace. These electric-powered top loading furnaces are available in single or two stage nitriding systems and are designed for applications that require high resistance to fatigue, impact and continuous metal-to-metal friction. LindbergMPH nitriding pit furnaces are available with operating temperature of up to 1200°F.
Steels for Nitriding Any steel will nitride, simply because of the presence of iron. However they will not produce the same hardness values because of the steel chemistrys. The iron will assist in the surface corrosion resistance by the formation of Iron Nitrides. Plasma Nitriding - an overview ScienceDirect TopicsPlasma nitriding equipment consists of a vacuum vessel (retort), a pumping system to control the furnace pressure, a plasma generator and a cooling system. Cold-wall furnaces use exclusively the plasma energy absorbed by the parts for heating, whereas hot-wall furnaces have a Principles of Gas Nitriding:The Nitriding Process (Part 1)Apr 04, 2011 · Nitriding is a case-hardening process in which nitrogen is introduced into the surface of a ferrous alloy such as steel by holding the metal at a temperature below that at which the crystal structure begins to transform to austenite on heating (Ac 1) as defined by the Iron-Carbon Phase Diagram (Fig. 1).The material typically is placed in contact with ammonia, which allows the transfer of
desirable vacuum furnace for pro-viding efficient uniform nitriding. Such a furnace was designed and de-veloped over several years to replace traditional retort gas nitriding . Furnace Considerations Two of the main factors in con-structing a vacuum furnace system for nitriding are the physical design of the furnace proper and the nitriding at- Vacuum Gas-Nitriding Furnace Produces Precision 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 metal retort too.
