Carbonitriding is a surface heat treatment that involves covering metal parts with gas or liquid mixtures. This treatment increases the surface hardness of the part by the diffusion of carbon and nitrogen. The carbonitriding process is used to treat metal parts that require greater surface hardness, typically low-carbon steels and small metal parts that are subject to wear (including screws, bolts and gears).
Carbonitriding typically takes place inside continuous ovens that can reach temperatures of approximately 930°C. The parts to be treated are moved inside the continuous oven on conveyor belts for high temperatures.
Costacurta conveyor belts for high temperatures are sized according to the operating conditions, the size of the parts to be treated and the workload, and are normally made in stainless steel 314 (W. Nr. 1.4841), NiCr 37/18Cb (W. Nr. 1.4887).
As well as guaranteeing a high-quality product, Costacurta provides technicians and engineers to assist clients in the selection of the most suitable type of belt for their machinery and processes.
