Nitriding Furnace

Nitride hardening is a versatile process that contributes to the manufacturing of numerous products, from aircraft parts to medical devices to power generation components. When you invest in reliable gas nitriding furnaces from Gasbarre, you’ll improve the quality and durability of your ferrous products.

What Is Nitriding?

Nitriding introduces nitrogen into a solid ferrous alloy by holding above the critical temperature (Ac1) in contact with a suitable nitrogenous material which may be solid, liquid or gas. Quench hardening is not required to produce a hard case.

Other common names and related subjects are case hardening.*

What Is a Nitriding Furnace?

Nitriding furnaces are heat treat furnaces designed to support the nitriding process. These ovens expose parts to active nitrogen at controlled temperatures to harden the metal, producing robust, wear-resistant products with high fatigue strength and long service life. Nitride hardening furnaces are typically used for ferrous-based materials, such as alloy steel, titanium, brass, zirconium and stainless steel.
