The High Fatigue Life Exhibited By Cold-pressed Needles Made Of Alloy Steel

crimp contact male is made of alloy steel, whose material properties remain stable under fatigue conditions. Alloy steel, through the blending of alloying elements and appropriate heat treatment, possesses both core toughness and surface hardness. Alloy steels used in mechanical structures often balance strength and toughness; after treatment, these steels can maintain good structural integrity under repeated loads.

Carburized steel, quenched and tempered steel, and spring steel are all variations of alloy steel, exhibiting high toughness in their core under impact or load. Surface carburizing or quenching treatment provides a hardened layer to resist localized stress concentration. Under this structural design, crimp socket contact exhibits a longer cycle life than ordinary materials under repeated cold working loads or mechanical stress.
