Introduction of spring steel wire

The strength of spring wire spring steel wire varies with varieties, standards and specifications, and the tensile strength grade can be in the range of 1000-3000 MPa.
The diameter range of round spring wire is 0.08-20 mm.
The cross-section shape of spring steel wire is generally round, and there are also rectangular, square, ovate and other shapes. The finished steel wire is generally delivered in a roll or in a straight strip.

Spring used in specific environment, there will be some special requirements for steel wire, for example: the spring used in corrosive medium must have good corrosion resistance. The instrument should have high sensitivity, low sensitivity and long-term stability. The spring working at high temperature is required to keep enough elastic limit and good creep resistance at high temperature.
