It is hoped that the smaller the plastic deformation, the better Therefore, the steel wire should have high elastic limit, yield strength and tensile strength.

Product Details

Screen wire mesh material: high-quality 45, 50, 55, 60 steel wire and 65 manganese steel wire, rebar, high-strength spring steel wire, low-carbon steel wire diameter: 0.4mm-16mm

The spring is used in the elastic range, and it should return to its original position after unloading. It is hoped that the plastic deformation is 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 strength utilization rate can be improved, and the elasticity of the produced spring is stronger.

Springs rely on elastic deformation to absorb impact energy, so the spring steel wire does not have to have high plasticity, but at least it must have plasticity that can withstand spring molding and sufficient toughness to withstand impact energy.

Springs usually work under alternating stress for a long time, so they have high fatigue limits and good creep and relaxation resistance.

Springs used in specific environments will also have some special requirements for steel wires. For example: springs used in corrosive media must have good corrosion resistance. The spring used in precision instruments should have long-term stability and sensitivity, a low temperature coefficient, a high quality factor, a small after-effect, and a constant elastic modulus. Springs working under high temperature conditions are required to maintain sufficient elastic limit and good creep resistance at high temperatures.

In addition, the forming process and heat treatment of the spring wire should also be considered. Cold-drawn spring steel wire and oil-quenched and tempered spring steel wire are directly wound around the spring in the state of delivery. After the spring is formed, it is used directly after stress relief. The tensile strength of cold drawn spring steel wire is slightly higher than that of oil quenched and tempered wire. The large-size cold-drawn steel wire has too much elasticity and it is difficult to wind the spring. Therefore, the cold-drawn spring steel wire is generally smaller than 8.0mm, and the oil quenched and tempered steel wire is generally smaller than 13.0mm. In fact, springs with a diameter of 13.0mm are mostly used in the spring steel wire in a lightly drawn state, which is formed after cold drawing and then quenched and tempered. Most of the steel wires with a diameter of 15.0mm or more are made by heating and winding.
