It is most commonly used for plain carbon steels. The case depths most commonly requested are in the 0. We have numerous furnaces capable of carbonitriding. If you have a large volume of parts, submit a quote request and we will respond promptly. Carbonitriding Capabilities on Furnace Variables All our carbonitriding cycles are run in batch-type furnaces for optimum process and lot-control.

All our furnaces are certified to the temperature accuracy and uniformity requirements of AMS The Carbonitriding Process The process of case hardening by carbonitriding is performed by austenitizing the heat-treat load in a controlled, carbon-rich atmosphere for a length of time commensurate with the case depth requirement, and then quenching the part in oil to harden the developed case. Selective case hardening is possible through the application of carb stop-off paints.

ThermTech is able to achieve conformance with carbonitriding requirements that other heat-treaters cannot conform to, due to our ability to polymer quench after a carbonitriding cycle. Expert Recommendations from ThermTech We often recommend the carbonitriding process to case harden heavy-gage stampings, low-alloy machined components, and gears. Typical case depths are in the. But with our superior capabilities and expertise, we can reach case depths in excess of 0. ThermTech offers this carbonitriding processes for many steel alloys.

The following are among those we treat most often: Case hardening of

Carbonitriding

Process[ edit ] Carbonitriding is similar to gas carburization with the addition of ammonia to the carburizing atmosphere, which provides a source of nitrogen. Nitrogen is absorbed at the surface and diffuses into the workpiece along with carbon. Carbonitriding tends to be more economical than carburizing, and also reduces distortion during quenching. The lower temperature allows oil quenching, or even gas quenching with a protective atmosphere. Characteristics of carbonitrided parts[ edit ] Carbonitriding forms a hard, wear-resistant case, is typically 0. Case depth is tailored to the application; a thicker case increases the wear life of the part. Carbonitriding alters only the top layers of the workpiece; and does not deposit an additional layer, so the process does not significantly alter the dimensions of the part.
