Spring steel wire

Spring steel wire is available in round, square, hexagonal, oval or trapezoidal cross-section. Such diversity makes it possible to use a wire in a variety of industries.

Manufacturing

For wire spring according to GOST 9389-75 are used steel with high carbon grades 51HFA, 68A, 70HGFA, 51HFA, 65GA, 68 GA, 70HGFA. And also from high-alloy stainless steel with the following brands: 12X18H10T 10H17N13M3T, 12H18N9, 17H18N9, 12X18H9T, 12H13, 10X17H13M2T, 30Ch13, 20X13, 40X13. From steels depend appearance wire and its physical characteristics.

Wire is manufactured with the help of drawing through the holes in which the diameter decreases. To get an accurate calibration of the wire, the last broach carried out through a calibrated die. That is, it allows to obtain very accurate spring wire shape and diameter, as well as a smooth and even surface. Then the wire is subjected to heat treatment, which improves its strength and spring properties. Also often released from the factory without wire heat treatment, since ultimately treatment will receive the finished product.

Application

Of springy steel wire manufactured springs, axles, pins, which are used in mechanical engineering, electrical engineering, construction. Before that produce pre-holiday began. Spring coiling can be performed and cold and hot method. Hot wire method involves heat to the tempering temperature, and navit windings, and then again oholodit product thereby producing hardening procedure. The spring wire of carbon steel used for spring winding in the cold state.

Accuracy spring wire may be normal or increased strength.

Wire spring mechanical strength classified on Grade A, B, C, as well as the classes 1,2, 3, depending on the values ​​of tensile strength.

Steel spring wire:

• grade B class 1.2 respectively GOST 9389-75 in coils up to 250 pounds, must have a value Ultimate tensile strength up to 100 N/m 2 or 10 kg/mm2; • model B3 and brands B1, B2, B3, 1.6 mm in diameter – less than -200 N/mm2, • model B3 and brands B1, B2, B3 a diameter greater than 1.6 mm – 150 N/mm2.

If the wire spring in its characteristics fall under two classes, it belongs to a certain class, which a lower value. Specifically for the furniture industry in the factory producing steel wire grade B 2.2 mm diameter, which has high accuracy and has a resistance value of about 1570-1770- N/mm2.

Spring wire carefully checked for cracks, scales, shells, dents, stains, bundles, and make sure that it was clean and smooth. Wire must fully meet the requirements of GOST 14963-78, TU 14-4-386-73, GOST 9389.

Shipping and handling

Before shipment to the consumer of the spring wire coated with preservative oil, which does not allow the product corrode. Deliver spring wire in coils, spools or coils. If necessary, it is additionally packed with moisture-proof paper or polyethylene.

You need to choose the spring wire in accordance with the needs and specifics of operation? This is not a problem on our site has all the detailed information about all kinds of wire spring. If you want, call us and we will help you with this.
