Because of its qualities such as surface uniformity and high load density, controlled gas nitriding is recognized as one of the best nitriding techniques available. It guarantees greater dimensional and surface morphology stability and, therefore, is applied to a variety of stainless steels components. Classical depassivation methods often contribute to a decreased corrosion resistance. In certain applications, alternative methods may be used to achieve the same extent of surface uniformity and similar results, without the use of classical halogen activation methods.
