Common Knowledge about Spring Wire
Published on January 6 2013
Classification of spring steel wire
Spring steel wire is a wire used to make the spring or wire form. In accordance with different purposes of the spring, the spring wire needed to make spring are available for various types, such as the spring wire with less demanding to do spring mattress (referred as the mattress wire), springs wire for shock absorber, spring steel wire for suspension spring, spring wire to do the engine valve, and spring wire to do the camera shutter. Although there is no uniform standard category name, the quality requirements of these spring wires are different. Spring wire can also be classified according to manufacturing processes, such as pulling spring steel wire (drawing without the lead quenching process), the lead hardened spring steel wire, galvanized spring steel wire, oil quenching spring steel wire, etc.
Different requirement for different spring wire
The strength of the spring wire can achieve tensile strength level in the range of 1000-3000 MPa according to different varieties, standards and specifications. Round spring wire diameter range is 0.08-20 mm. The sectional shape of the spring wire is generally is circular, there are also rectangular, square, oval and other shapes, the finished steel are generally delivered in rolls, there are straight delivery cases too. The wire spring used in a particular environment will have some special requirements for the steel wire, such as: the spring using in the corrosive medium must have good corrosion resistance. The springs used in precision instruments should have a long term stability and sensitivity, low temperature coefficient, high quality factor, small after-effect, the modulus of elasticity should be constant. The spring work under high temperature conditions is required to remain sufficiently resilient limit and good creep resistance at high temperatures.
The use characteristics of the spring wire
The spring used in the elastic range should revert to its original position after unloading, the smaller the plastic deformation, the better. So the wire should have a high elastic limit, the yield strength and tensile strength. The higher the yield ratio, elastic limit is closer to the tensile strength, and thus it is more able to improve the strength utilization, the spring force will be stronger. Spring rely on elastic deformation to absorb impact energy, so the spring wire does not necessarily have a high plasticity, but the
must be at least able to withstand the molded plastic of the spring, and enough toughness be able to withstand the impact energy. Spring usually long-term work under alternating stress, and therefore it should have a high fatigue limit, as well as good resistance to creep and relaxation properties.
