- Gas Nitriding of stainless steel Nitreg®-S -

Stainless steels respond to nitriding differently than other ferrous alloys, and there are significant differences within the stainless group as well. The primary reason is that, depending on the chemistry of the steel, it will behave differently with regard to the kinetics of layer formation, and it is a rather difficult process to control. In other words, unless you know what you are doing, you may end up with nothing, too little or too much case depth or white layer, or even damaged parts.

NITREG®-S is a process in which any stainless steel may be nitrided, with complete control over the formation of nitrided layers. All types of stainless steel can be nitrided.

NITREG®-S Advantage

• No need for pre-processing parts preparation. In-furnace de-passivation and nitriding.
• Excellent wear resistance
• Improves fatigue strength
• Prevents galling
• Does not alter the alloy’s chemical composition
• Has no effect on the steel’s non-magnetic nature
• No change in colour, shape or size
• Controls the thickness of the compound (white) layer and its properties
• Eliminates closed nitride networks within the diffusion zone
• Excellent control of case depth
• Uniformly hardened even small bores, tight grooves and sharp edges
• Excellent control of the surface hardness
• Very high level of process repeatability
• Green technology, no waste pollution
