Product Description
ZHENGDE Stainless Steel Spring Wire/Spring Steel Wire Rod is the
most commonly used part in the machinery industry and in daily
life. The main function of the spring is to use the energy stored
in its own deformation to ease the vibration and impact of the
machine or parts, and to control the movement of the machine or
parts.
The use characteristics and uses of spring steel wire
The spring is used within the elastic range, and it should return
to its original position after unloading. It is hoped that the
plastic deformation should be as small as possible, so the steel
wire should have high elastic limit, yield strength and tensile
strength. The higher the yield ratio, the closer the elastic limit
is to the tensile strength, so the higher the strength utilization
rate is, the stronger the elastic force of the spring is.
The spring relies on elastic deformation to absorb the impact
energy, so the spring steel wire does not have to have high
plasticity, but at least it must have the plasticity to withstand
the spring forming and enough toughness to withstand the impact
energy.
Springs usually work under alternating stress for a long time, so
they must have a high fatigue limit, as well as good creep and
relaxation resistance.
