Quality Services

We believe quality through Process Control. Our Furnace is Electrically heated having dual temperature controller one is for bath & other is for jacket temperature. This ensures uniform & accurate temperature of bath. We are having FULL PHASE CHEMICAL & METALLURGICAL Laboratory.

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 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 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.

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.
