60Si2Mn Spring Steel Wire

Henan Friend Metal Products Co., Ltd. is one of the leading manufacturers and suppliers of 60si2mn spring steel wire in China. If you're going to buy 60si2mn spring steel wire made in China, welcome to get more information from our factory. We also accept customized orders.

60Si2Mn spring steel wire is a major material used to make structural parts of various springs and elastic elements or similar performance requirements.

1. performance requirements

The high elastic limit E and the strength ratio s/ B are used to ensure good elastic properties, i.e., to absorb a large amount of elastic energy without producing plastic deformation;

The high fatigue limit, the fatigue is one of the main failure form of the spring, the structure and the composition of the steel in fatigue performance, mainly by the metallurgical quality of steel (such as non metallic inclusions) and spring surface quality (such as decarburization) effect;

Sufficient plasticity and toughness to prevent impact fracture;

Other properties, such as good heat treatment and plastic processing performance, heat resistance or corrosion resistance requirements under special conditions, etc..

2. component characteristics: the content of carbon and alloying elements in steel:

(1) in general, high carbon, carbon spring steel wire 60Si2Mn WC = 0.6%~0.9%, WC = 60Si2Mn alloy spring steel wire rod 0.45%~0.70%, after quenching and tempering after tempering troostite, can ensure the performance requirements of spring.

(2) alloy elements, general purpose alloys, 60Si2Mn springs, steel wires and wires are generally low alloy steels. With the main elements of Si, Mn and Cr, its main role is to improve the hardenability, solid solution strengthening matrix and improve the tempering stability; adding elements of Mo, W, V and other strong carbide forming elements, main function is to prevent overheating, decarburization defects caused by Si defects in Mn and improve the tempering stability and heat resistance.
