Carburizing is a heat treating process in which iron or steel absorbs carbon liberated when the metal is heated in a carbon enriched atmosphere. The process leads to a hardening of the metal which allows the product to be used in a wider variety of outputs due to the increased hardness. Longer carburizing times and higher temperatures typically increase the depth of carbon diffusion. The process often ends with the iron or steel being cooled rapidly by quenching the product in some type of liquid. This quench finalizes the hardening process. Modern can also selectively carburize parts to your specifications.
Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a hardened surface. Nitriding is most commonly used on medium and high-carbon steels, nitralloy, and several others.
Ferritic Nitrocarburizing encompasses a range of case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures. The processing temperature ranges depending on the job. FNC has a high resistance to wear and it’s more resistant to corrosion than other types of processing.
Carbo-nitriding is a metallurgical surface modification technique that’s used to increase surface hardness of a metal as well as reduce wear. The carbo-nitriding process involves the diffusion of both carbon and nitrogen into a base steel which can be carried out in a furnace gas.
