Spring Steel refers to a group of a low alloy, medium carbon steel or high 

carbon steel with excellent yield strength. Our SMC is the leading manufacturing 

and supplier of sprig steel products. We use high grade of 

raw materials to ensure premium quality and high tensile.

Specifications of Spring Steel Strip:
1) Grade: 45, 50, 55, 65, 70, 75, 85, 65Mn, 55SiMnV, 60Si2MnA, 60Si2CrA, etc.
2) Thickness: 0.3mm - 2.0mm
3) Width: 30mm - 355mm
4) Hardness: ≥100HV
5) Surface Treatment: grey, blue, bright, bright & grey, bright & blue

The final product typically consists of cold rolled steel that has been cut into 

strips of a specific widths and coiled or oscillate coiled for delivery, 

frequently interleaved with paper or another material which protects the surface 

finish of the material and assists in retaining oil or some other rust prevention solution. 

This product is often later stamped to form a part from the strip steel.

Packaging of Spring Steel Strip

Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

Features of Spring Steel Strip:

The chemical compositions helps spring steel to endure 

significant bending or twisting and return to its original shape without deforming.

Strip Steel or cold rolled strip is a steel product that is produced from a hot

rolled strip that has been pickled. The coil is then reduced by a single stand

cold roll steel mill straight away or reversing mill or in a tandem mill consisting

of several single stands in a series. The strip is reduced to approximately final

thickness by cold-rolling directly, or with the inclusion of an annealing operation

at some intermediate thickness to facilitate further cold reduction or to obtain

mechanical properties desired in the finished product. High carbon strip steel

requires additional annealing and cold reduction operations.

The coil is then slit to the desired width through the process of roll slitting.
