Often favoured for components that are subjected to heavy loading, nitriding imparts a high surface hardness which promotes high resistance to wear, scuffing, galling and seizure. Nitriding increases fatigue strength by the development of surface compressive stresses. With a wide range of possible temperatures and case depths Pazmac is able to adjust different properties of treated parts to your custom requirements.


Beyond the manual loading and unloading our gas nitride system runs with minimal supervision helping maintain low operating costs. As gas nitriding keeps your parts dimensionally stable, little or no post heat treat operations are required


Pazmac processes a control coupon with each load. The coupons are catalogued and stored on site. Upon request the coupons are available for testing by either Pazmac or the customers approved lab. Each load is shipped with a detailed time-temperature chart and certificate of conformance.

Software Controlled

Pazmac’s gas nitride process provides well controlled case depths and consistent surface hardness as well as maintaining a white layer thicknes of 20u or less.

Dimensionally Stable

Gas nitriding is a stable process which eliminates thermal shock during the heating and cooling stages. This also provides a dimensionally stable part with low distortion due to the reduced stresses imposed on the base material.

Surface Hardness and Case Depth

Parts can achieve a surface hardness up to the mid 60’s HRC with tightly controllable case depths of 0.002-0.030”


Pazmac’s gas nitride system is capable of loading parts up to 96” in length and 37” in diameter. Small parts can be process in large batch sizes.


Pazmac’s gas nitride system is environmentally safe and meets all current environmental standards


The gas nitride process requires a clean environment to achieve best results, the benefit to the end user is clean and residue free parts, ready for immediate use

Corrosion Resistance

Parts processed in Pazmac’s gas nitride furnace can also be provided with a superior corrosion resistant coating using the Nitreg-C option
