Carbon spring wire GOST 9389-75
it is used for the manufacture of springs that are wound in a cold state and are not subjected to hardening, and also, as a wire with elastic and rigid properties, it is used: for pulling a cable in pipes, suspending a cable, cleaning the sewer, for the manufacture of spring blocks for mattresses, traps, plumbing cables, in modeling, as well as in the production of various household and useful products.

The wire will be supplied with or without lubrication, in coils: d.0.2mm-0.8mm in skeins of 18kg-80kg, d.1mm-4mm from 90-250kg, d.5-8mm from 300kg-1.5tn. We offer for delivery spring piano wire GOST 9389-75 wholesale and retail in skeins of 1 kg.

Class 1 wire according to GOST 9389-75
High tensile strength. The presence of large final stresses of the first order (from drawing and winding) causes the appearance of final spring deformations at stresses t 3 > 0.32 Rm. When v max > v k, the final deformations are high regardless of the application of the enslavement operation.
Wire of classes 2 and 2A according to GOST 9389-75
It differs from class 1 wire in reduced breaking strength and increased plasticity. It is used for products operating at low temperatures, as well as for tension springs with complex hook designs. Class 2A wire differs from class 2 wire in higher dimensional accuracy, reduction of harmful impurities in the metal, and further increase in plasticity.
