Nitriding Applications

Power Transmission (Shafts & Cranks)

Properties of small shafts exposed to atmospheric conditions and/or other corrosive environments are frequently treated in an in-process post-Nitriding oxidizing treatment. Such components have excellent wear and corrosion properties, as well as an attractive appearance. Shafts made of stainless steel or nickel based alloys require vacuum hardening and tempering, frequently followed by Nitriding. High performance automotive and aircraft engine crankshafts are nitrided for better fatigue resistance and wear properties on bearing journals.

 

 

Tooling Applications

Nitriding properties required for dies and other toolings are high wear resistance, impact strength, resistance to softening, and high dimensional stability. We offer with its precise control of surface concentration of nitrogen makes it possible to obtain reproducible properties of treated parts, and consequently improve tools performance

 

Forging / Forming Dies

Forging and forming dies made of tool steels, alloy steels, cast steels or cast iron are frequent visitors in a heat treating shop. The dies are vacuum hardened and tempered, flame hardened, flood-welded, and nitrided, as applicable, for better life.

 

Mechanical Components (Gears)

Nitriding gears for applications ranging from heavy-duty machinery to small automotive accessories enable lower manufacturing costs. For one customer, this meant eliminating costly finishing operations needed after carburizing.

 

Engine Piston Applications

Nitrided piston rings show high surface hardness at elevated temperatures, and good sliding wear resistance with a low coefficient of friction.

 

 

Suspension System Applications and Springs

Springs are routinely nitrided to enhance their fatigue resistance to premature failure.

 

Fuel Engine System & Valves Application

Nitriding is the appropriate method for improving the wear resistance of small cross-section parts or those that easily lose their shape. A good example of such a part is the fuel injector, which requires a high wear resistant surface necessary to prevent abrasion by a high-velocity fuel stream.

 

Die Making Applications

Extrusion dies are nitrided and re-nitrided several times to extend their die life. Nitriding parameters are adjusted to the expected die duty cycle resulting in significant cost reductions and virtual elimination of unscheduled press shutdowns.
