Low-pressure nitriding

Explore our low-pressure nitriding treatment, a heat treatment technique that enriches the surface of metals with nitrogen to dramatically improve their resistance to wear, galling and fatigue. This process is essential for parts requiring high surface hardness without altering their core structure.

The benefits of this treatment

Low-pressure nitriding is distinguished by its ability to create a surface combination layer of iron nitrides and a diffusion layer, increasing surface hardness up to 1100 Vickers (hardness index) depending on the steel grade.
This treatment is carried out under low-pressure conditions facilitating better absorption of nitrogen by the metal surface, enabling uniformity to be achieved even for complex geometries. Thanks to precise computerized management, each treatment parameter is controlled to ensure consistent quality and optimize mechanical properties according to your specific requirements for each part. This technology uses vacuum furnaces, which greatly reduce process gas consumption.

A treatment applicable to different sectors

Mainly used in sectors such asautomotive,aerospace and tooling, low-pressure nitriding is ideal for components subject to high stresses. These treated parts, such as shafts, gears and plastic injection molds, benefit from enhanced strength under rigorous operating conditions. The process is particularly effective for special steels, and can be adapted to treat stainless steels (especially those with special precautions). The method also reduces production costs thanks to optimized treatment cycles and high loading density.
