Nitrocarburizing is a surface hardening method, suitable for steel parts that calls for increased durability and improved fatigue resistance.

When the process is performed at low temperature the shape and dimension will change very little. All grades can nitrocarburized, but the surface hardness results are dependent on the alloy content of the material. Higher alloy content - higher hardness. Nitrocarburizing is suitable for components such as hydraulic and shafts, cylinders, crank and cam shafts, pistons, tools, etc.
