Applications

• GKP is used to produce nitrided parts which need to be extremely stable after hardening and tempering treatment.
• It is particularly suitable for deep nitriding.
• Gears, crankshafts, precision parts, aircraft parts.

Mechanical properties

• Nitriding steel with an excellent level of hardenability and particularly high mechanical properties, impact strength and fatigue limit.
• It may be nitrided in the heat treated condition with a core strength of 900 N/mm2 to 1450 N/mm2. The nitrided layer is not brittle.
• In comparison with other nitriding steels, GKP allows the nitriding process time to be reduced by up to 40 % for the same nitrided layer depth.
• With the same nitriding process time, GKP results in a depth gain of up to 0.2 mm. GKP makes it possible to obtain nitrided layers with a depth of about 0.9 mm.
