Recommendations

Soft shot peening

Before the nitriding process a soft shot peening process shall be applied in order to remove the oxide layer on the spring wire surface.

Nitriding

GARBAFLEX CrSi91 should be nitrided to obtain optimum fatigue and relaxation properties. Our recommendation is gas nitriding.
