Standard for Carbon Spring Wire


Carbon spring steel current country and work recommended standard sub-two types:

1, cold drawn spring wire

One is cold deformation reinforced steel wire, also known as cold drawn spring wire. Cold-drawn carbon spring steel wire is mainly subjected to lead quenching treatment to obtain sorbite structure, and then surface phosphating, with a large reduction in the rate of drawing to the product standard, the steel wire was fibrous, with high tensile strength and elastic limit , Excellent bending and alteration function. Cold-drawn spring wire standard high precision, the surface light, no oxidation and decarburization defects, fatigue life ratio is stable, is the most widely used spring wire.

2, oil quenching and tempering steel wire

Another type of carbon spring steel wire is martensitic reinforced steel wire, also known as oil quenched and tempered steel wire. Carbon steel wire by quenching and tempering treatment, access to excellent general mechanical function, when the wire standard is small (φ ≤ 2.0mm), oil quenched and tempered wire of the strength of the policy than the sintered treatment of cold drawn steel wire is lower The When the wire standard is larger (φ ≥ 6.0mm) Saussure steel wire can not use a large reduction rate to obtain the required strength policy, and oil quenched and tempered steel wire can be completely hardened to get more than cold Pull the wire higher function. Under the same tensile strength, the martensite reinforced steel wire has a higher elastic limit than the cold deformation reinforced steel wire. The microstructure of the cold drawn steel wire is fibrous, and the anisotropy is obvious. The microstructure of the oil quenched and tempered steel wire is homogeneous tempered martensite, almost isotropic. With the oil quenching and tempering steel wire anti-slack function is better than cold drawn steel wire, the use of temperature (150 ~ 190 ℃) is also higher than the cold drawn wire (≤ 120 ℃). In the middle of these years, large standard oil quenching, tempering wire has a great way to replace the cold drawn steel wire.
