General Characteristics

Stainless spring wire is a long-length metal product, used in the manufacture of springs. Material for its production is high alloyed stainless steel grades: 12Х18Н10Т, 12Х18Н9, 12Х18Н9Т, 10Х17Н13М3Т, 10Х17Н13М2Т, 17Х18Н9, 20Х13, 12Х13, 40Х13, 30Х13. Depending on what steel the spring wire is made of, it will be brightened or darkened, hard or soft.

Classification

According to the method of manufacture:

- heat-treated;
- cold drawn.

By type of treatment:
-oxidized - T of steel grades 20X13, 12X13, 40X13, 30X13;
-Bright stainless steel wire -ТС of steel grades 12Х18Н9, 08Х18Н10, 12Х18Н10Т, 10Х17Н13М2Т, 12Х18Н9Т, 17Х18Н9, 10Х17Н13М3Т, available in diameter of 0,3-0,6 mm; This wire is the most popular in its category.

The accuracy of manufacture can be:
- increased - P;
- normal.

According to the physical properties, the wires are divided into two plasticity classes:
1st class;
2-nd class.

Quality requirements

The wire surface should be smooth and clean, without any cracks, delaminations, pits, dings, rust, scale, oil traces. High-quality spring stainless steel wire that meets all necessary requirements of GOST 18 143-72 and TU 3-1002-77; EN 10 270-3 is manufactured only under industrial conditions.

Advantages .

The spring stainless wire features high fatigue strength and high corrosion resistance. High-precision modern equipment installed at production facilities allows the springs to achieve a uniform shape. The springs manufactured from GOST 18 143-72 wire can be used in manufacture of various types of springs: compression or torsion expansion.

Application

Production of springs of various categories, performance of welding works. Such wire is in demand in various industries, most often - in construction, machine building, consumer goods and medical equipment production. The demand for it is constantly growing.
