Spring steel wire D 1.6 mm GOST 9389-75 Grade St 70

Steel wire spring D 1.6 mm GOST 9389-75 Grade St 70 is one of the special types of wires, stands in a special row among other types of hardware products. Due to its mechanical properties such as resilience and flexibility, its main application is in springs. For the manufacture of spring wire, the following steels are used: carbon, alloy, structural spring-spring steel 60s2a, 65G, 70.

The main value of the wire is the ability to spring. This property is achieved through heat treatment.

According to the manufacturing method, the springs are divided into cold (HN) and hot (HN) springs.

Spring wire is used in the production of furniture springs, hairpins, hooks, automobile mechanisms.

Spring wire is produced according to TU 14-4-386-73, GOST 14963-78, GOST 9389-75. Spring wire is used for cold winding of springs, as well as for household and other needs.

Mechanical properties are of several classes:

- first class - springs for special and important purposes, where the degree of importance is high, and the deviation is breaking resistance 200 N / mm2;

- the second class is used for springs of general use, where the degree of responsibility is lower, and the deflection resistance of the second class is 340 N / mm2.

This wire has also found application in the creation of interior elements. Due to the ability to easily shape the required shape (the increased strength of the spring wire also played a role), many designers use it as finishing elements. It is often used by manufacturers of furniture products for decoration.
