General characteristics

Stainless spring wire is lengthy metal product, main purpose of which manufacture of springs. Its production is strictly defined steel grades 12X18H9T, 12H18N9, 12X18H10T 10H17N13M3T, 10H17N13M2T, 17H18N9, 20X13,12H13, 30X13 and 40X13. The choice of grade of steel for spring wire defines its main characteristics, including color and appearance. Depending on the brand of stainless steel produce wire will have a bleached or dark color and will also be more rigid or plastic.


A method of manufacturing a spring wire determines its future characteristics and scope of the assignment. To date, there are two methods of manufacturing this product: hot processing and cold drawn method. The standard provides several kinds of processing of the finished product. Spring wire can be oxidized (T) — for its production uses such steel grades: 20X13, 40X13, 12H13, 30CH13, and bright (CU), which is made from such steel grades: 08H18N10, 12H18N9, 12H18N10T, 12KH18N9T, 10H17N13M2T, 17H18N9 and 10H17N13M3T. The last type of wire is the most popular in modern industry, and is available in different cross section from 0.3 to 0.6 millimeters.

The technological process of production spring wire means and various precision manufacturing of this product. Accuracy can be as high (P) and normal (N). Physical characteristics of spring wire include its plasticity, which is divided into two classes: first (1) and second (2).


For the products of high-alloy stainless steel is used a number of quality requirements, which normalized following the state standards — GOST 18143−72, THE 3−1002−77 and EN 10270−3. The surface of the spring wire must be absolutely smooth and clean, without visible cracks, holes, delamination, nicks and rust. It is also unacceptable the presence of scale or oil traces.


The undeniable advantages of spring wire of stainless steel include its high threshold fatigue strength, and high resistance to different types of corrosion. Modern high-precision equipment installed at industrial facilities and helps to achieve a uniform shape of the springs. For example, the spring wire, which is produced according to GOST 18143−72, is widely used for manufacturing various types of springs: compression, extension and torsion.


The spring wire used for the production of springs of different categories, and also to perform many types of welding. Most often this wire is used in construction industry, engineering, chemical and light industry, production of medical equipment, furniture manufacture and the manufacture of consumer goods. The demand for this product never falls.
