Induction Tempered Wire

About this product

Best in Class Induction Hardened and Tempered Spring Steel Wires Induction tempered wires are the most common yet least known things in our lives. It means that we keep on using them on different fronts of our lives without realizing their presence. For example, the spring wires that you often refer to as “shockers” are in fact induction tempered wires and they are made in such a way that no amount of physical interference can possess a threat to your lives while you are driving a certain vehicle. Our induction tempered wires are one of the best in class induction tempered wires as they adhere to all the quality standards set by the respective authorities in the country, and when you incorporate the wires manufactured by us into different mechanical objects, you will get nothing but satisfaction from their performance. So let’s dig deeper and find out what these wires are all about and why you should consider only DP Wires when you are thinking of buying one. What is an Induction Tempered Wire? Induction is the process of transferring energy from one place to another and when we talk about an induction tempered wire, the meaning of induction remains the same. The making of induction tempered wire is done so that its strength, ductility, sag resistance and other such mechanical properties can be increased. It is important to achieve this goal because it is hard to imagine a mechanical object which requires a wire for its proper functioning but that wire does not have the strength to carry out the processes of that machine efficiently. An induction tempered wire is made by subjecting a normal wire to oil tempering by the means of electric energy or gas for heating and oil or water for quenching.

Induction Tempered Wire Normally Induction Tempered Wire is categorized as Oil Tempered Wire for its mechanical properties, however, DP Wire's advanced and unique production system uses electric power instead of gas as an energy source for heating and water instead of oil for quenching. Principle of Induction Heat Treatment: Induction heat treatment is, as you can see in fig 1, one of the heat treatment methods assembled, under accurate control, with the Induction Heating Process and Rapid Cooling System which can cool wire material uniformly besides rapidly. This system not only materializes excellent properties of the material but also enables us to heat material so rapidly up to targeted temperature per its application without touching anything. Induction Heat Treatment is quite effective for non-pollution systems suitable for saving resources and energy. Features From the wire rods to finished products, it is manufactured following perfect quality control by latest facilities and supreme technology, with an automatic induction heating system developed by us . D.P. Wires Induction Tempered Wire has the following features: Because of rapid and short time induction heat treatment for austenitization, • Fine grain structure can be gained. • Decarburization or oxidation of grain boundary. Because of the interaction of fine quenched structure and short time induction tempering, • High strength and toughness can be obtained at the same time by using the precise control system for heating, quenching & tempering. Temperature is controlled for each wire at each stage of operations. • Product's Tensile strength can be achieved according to the customer's specification. • Uniform strength for the entire length of wire can be obtained. • Possible to form smaller D/d springs even using higher strength of wire. • Fatigue and sag resistance remains at high level. • Cost reduction will be possible by weight saving due to high applied stress. Manufacturing Process D.P. Wires Induction Tempered Wire is manufactured and shipped according to the process shown in Fig. 2. Through this process like descaling & coating, drawing, quenching, and tempering the wire is heat-treated to provide the required mechanical properties and is continuously inspected by an eddy current flow detector. Standard Specifications Chemical composition Wire rod of SAE9254 mainly and other similar grades with special elements are used as raw material. Diameter range : Size : 6.0 mm to 17.0 mm. (Please ask us for smaller diameters than 6.0 mm) Tolerance and Out of roundness Tolerance and Out of roundness are as shown in Table 2. Mechanical properties Standard mechanical properties are as shown in Table 3. Instructions for safety use Handling and Storage : Pay strong attention to ensure that the wires do not have flaws, scratches, abrasions, bruises, and other wounds on the wire. Keep away the wire from moisture such as rain, high humidity, or chemical to ensure that corrosion on the wire doesn't take place. Keep away from the electric or cutting spark. Even such small surface defects may cause the breakage of spring. • Do not use steel wire rope but use nylon sling for lifting. • It is recommended to put the wire on a rubber sheet or squared timber for storage. • Rewinding stand must be used for rewinding of wire in the coil. It is recommended to use a rewinding stand with low frictional resistance. • Be careful with the spring back of the wire's end when cutting the bindings for wire in the coil. • Do not apply plating to the springs processed from the wire. • Low annealing temperature must be done after the formation of coil spring within 24 hours. Application Spring Steel Wire Seat Spring for two-wheeler & four-wheeler. Suspension/Compression Springs • Tension Springs • Torque Spring Conditions of low temperature annealing Recommended conditions Following are the recommended conditions for low temperature annealing to be processed after forming of coil spring using SWI-180 and SWI-200 respectively. Comparison between "JIS G 3560" and "D.P. Wires" • USAGE Suspension in two and four wheel vehicles, emergency brake for large-sized vehicles, shutter,industrial machine and other springs need high fatigue resistance and high sag resistance.
