QPQ is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. Three steps are involved: nitrocarburize ("quench"), polish, and post-oxidize ("quench"). ... corrosion resistance. lubricity.

Thermal Heat Flattening Treatment / Services Treatment, flattening and Coating Line (FCL)and our setup is situated in Pune, Maharashtra, India. Thermal Heat Flattening Treatment / Services and Ovality Correction are processes where parts are subjected to pressure during a stress relieving or temper operation for the purpose of improving the overall flatness and ovality of ring shaped parts. Parts can be flattened up.

Our process is non-pollutive, sulphar accelerated at low temperature (570 + 100 C ). It is an ideal process to improve the resistance of ferrous materials to wear, seizure, corrosion & fatigue. For a specified period of time of soaking of components in bath, produces a compound zone of 10-25 microns & nitrogen diffusion layer of 0.2-0.6mm. It advantageously replaces shallow depth case hardening  & carburising.

The oxidising process has been developed to further improve corrosion <br>resistance of ferrous material previously liquid nitrated. The process is carried out at 425 + 250 C, provides a pleasing black colour. This process can replace hard chrome in number of applications. This process eliminates problems like peel off, hydrogen embrittlement & non uniform plating thickness.

It is a modified form of gas carburising. In this Process the nitrogen diffuses into the steel<br>simultaneously with carbon. Carbonitrided case has better hardenability & wear resistance than carbunised case. For many applications, carbonitriding the less expensive steel will provide properties equivalent to those obtained in gas carburised alloy steels. Steel Commonly carbo-nitrided includes those in the 1000, 1100, 1200, 1300, 1500, 4000, 4100, 4600, 5100, 6100, 8600 & 8700 AISI series of low carbon steels.<br>Medium carbon or alloy steels are often carbo-nitrided to provide  better wear resistance than conventional hardening. Case depth in carbo-nitriding is limited to 0.3 to 0.7 mm.

• Furnace is having Oxygen probe & Milli-volt Controller facility to control surface carbon accurately. • It is also having facility for nitrogen purging & ammonia dissociation  unit for gas nitriding.
