51CrV4 DIN 17350-1980 spring steel wire

Spring wire is a kind of wire material mainly used for making spring or wire type parts. According to different application requirements, there are many types, such as mattress wire, shock absorber wire, suspension spring wire, engine valve wire and camera shutter wire.

Spring steel wire can be classified according to the manufacturing process, such as raw spring steel wire, lead quenched spring steel wire, galvanized spring steel wire, oil quenched spring steel wire.

Spring steel wire has a high tensile strength, tensile strength grade can be in the range of 1000-3000 mpa. Its interface shape is generally round, but it also has rectangular, square, oval and other shapes, and the diameter of the circular spring wire ranges from 0.08-20 mm.

Spring steel wire needs to have good elasticity, toughness, fatigue resistance and corrosion resistance in some special environments.

Spring steel wire in the production process usually includes raw material preparation, smelting, rolling, heat treatment, cold drawing and surface treatment and other links. Different types of spring steel wire have different production methods. But the common feature is to ensure that the steel wire has a certain strength, high toughness and good spring coiling performance.

Special requirements:

Springs used in corrosive media need to have good corrosion resistance.

Springs in precision instruments require long-term stability and sensitivity.

Springs in high temperature environments need to have sufficient elastic limits and creep resistance.

Spring steel wire is an important metal material, its performance and quality directly affect the performance and service life of the spring and steel wire parts made, with the development of science and technology and industry, the production process and application field of spring steel wire are also constantly expanding and improving.
