General characteristics

Stainless spring wire is metal long product, used in manufacture of springs. Material for its production is high alloyed stainless steel, grades: 12H18N10T, 12H18N9, 12H18N9T, 10H17N13M3T, 10H17N13M2T, 17H18N9, 20H13, 12H13, 40H13, 30H13. Depending on which steel spring wire is made of, it will be lightened or dark, hard or soft.

Classification

According to manufacturing method:

— heat treated;
— cold drawn.

By type of processing:
— oxidized — T from steel grades 20H13, 12H13, 40H13, 30H13;
— light stainless wire -TS made of steel grades 12H18N9, 08H18N10, 12H18N10T, 10H17N13M2T, 12H18N9T, 17H18N9, 10H17N13M3T, available with diameter of 0.3−0.6 mm. This wire is most popular in its category.

Manufacturing accuracy may be:
— increased — P;
— normal.

According to physical properties of wire are divided into two classes of ductility:
1st grade;
2nd grade.

Quality requirements

Surface of wire should be smooth and clean, without any cracks, delaminations, sinks, nicks, rust, scale, oil marks. High-quality spring stainless wire that meets all necessary requirements of GOST 18 143−72 and TU 3−1002−77; EN 10 270−3. manufactured only in industrial conditions.

Advantages

Stainless spring wire is characterized by high level of fatigue strength and high corrosion resistance. High-precision modern equipment installed in production allows achieving uniform spring shape. Springs made from GOST 18 143−72 wire can be used in manufacture of various types of springs: expansion of compression or torsion.

Application

Production of springs of various categories, welding. Such wire is in demand in wide variety of industries, most often in construction, engineering, production of consumer goods, medical equipment. Demand for it is constantly growing.
