Gas Nitriding

Process

AMS 2759/6 & AMS 2759/10
Gas Nitriding is a surface hardening process in which nitrogen is added to the surface of steel using dissociated ammonia as the medium.  The result is a very hard vase component achieved using a low temperature and alleviating the need for quenching.  Recent developments utilizing computer control of the atmosphere have led to a process that can be accurately controlled.  The thickness and phase formation of the Nitriding layer can now be selected and precisely maintained.

Specifications

As with other nitriding processes, Gas Nitriding is carried out at temperatures below what would be required to transform alloy steel.  When combined with the proper manufacturing techniques, minimal distortion is observed at these lower temperatures.  This results in a very high strength product with extremely good wear resistance.  Additionally, Gas Nitriding permits large batch sizes, meaning furnace and gas flow are the sole limitations.
The typical temperature range is 925F – 1050F

Applications

Valve Parts, extrusion screws, plastic mold tools, forging dies
