Nitrex Gas Nitriding System

Gas nitriding is a specialized process designed to impart a wear resistant surface onto finished machined components. The process uses dissociated ammonia that interacts with elements like chromium, molybdenum, and titanium to form very hard nitrides. These nitrides do an excellent job increasing surface hardness as deep as 0.035” depending on the material.

This process is very practical for precision machined components, as the temperatures used are below the transformation temperatures of steel. This limits the dimensional distortion typically seen from other surface treatments like carburizing. Vacu-Braze uses two-stage gas nitriding which also helps to limit the growth of white layer, a very hard and brittle layer that typically needs to be machined off. A variety of materials can be effectively nitrided as finished parts such as alloy steels like 4340, tool steels like H-13, or stainless steel like 304.

In addition to traditional nitriding, we can utilize our equipment to offer other services such as nitrocarburizing and ferritic nitrocarburizing (FNC). Nitrocarburizing utilizes similar processing temperatures to traditional nitriding but also introduces carbon into the surface of the steel to make carbides as well as nitrides. This can be used to achieve a higher hardness and also uses a faster cooling rate. FNC is used to increase the surface hardness of carbon steels, as well as increase their corrosion resistance.
