How dose temperature influence spring steel wire?

Spring steel wire will influence by many factors, such as the corrosion medium, temperature and so on. As an enterprise specialized in making spring steel wire and spring making machine, we will introduce to you that how dose the temperature influence the spring material.

The elastic modulus of spring steel wire will decrease, if the temperature of spring working environment increases, and the stiffness will decrease as well, the load capacity will be weaken. So the spring steel wire working under high temperature requires good heat stability, good resistance to loose and creep, good resistance to oxidation. What’s more, we should understand the changing rate of elastic modulus and measure the influence to the operational performance because of the decrease of load capacity.

The high temperature will influence the spring steel wire, so does the low temperature. The spring steel wire using under the low temperature should possess good low temperature toughness. Carbon spring steel wire, piano wire, and stainless steel spring wire have good low temperature toughness and strength. Under the low temperature, the brittleness of materials is very sensitive to surface defects, so the requirement to the surface quality of spring steel wire should be strictly. Under the low temperature, the corrosion of environment medium to the material is smaller. Under the low temperature, the elastic modulus of spring steel wire has little change, so we needn’t to consider during the design.

All in all, temperature has a great influence to spring steel wire, also to the spring, so we need to understand it.
