Carburizing, Nitriding, and Hardening
Expert solutions to help you succeed
Air Products’ Atmosphere Solutions are available for carburizing, neutral hardening, carbonitriding, nitriding and nitrocarburizing. Nitrogen, methanol, and/or a small amount of enriching gas are blended at the furnace to provide a furnace atmosphere essentially identical in composition to that of endothermic. By varying the amount of enriching gas, the furnace carbon potential can be adjusted to meet your specific atmosphere requirements. The benefit of Air Products’ Atmosphere Solutions is superior atmosphere control for consistent part quality, operational cost savings, significant increases in operational productivity, and ease of operation.

Ask the Expert
Guido Plicht
Commercial Technology Manager - Europe
“How can I achieve a more homogeneous surface hardness in controlled-atmosphere carburizing?”
In atmosphere-carburized parts, especially bulk loads, variations in surface hardness might appear. This is a common issue caused by insufficient atmosphere circulation inside the furnace chamber and through the load. At Air Products our atmosphere flow modelling capabilities enable us to simulate and solve these technical barriers. Our specialists can work with you to find the best way to modify the load set-up, thus improving the carburizing results.
