60Si2MnA wire is a spring steel wire rod. It has excellent performance due to the precise chemical composition, high strength, elastic limit and certain toughness. It can absorb energy and prevent sudden breakage when subjected to impact or vibration. It is suitable for manufacturing springs and mechanical parts with high strength requirements. At the same time, rapid spheroidizing heat treatment can be used to replace the traditional spheroidizing annealing process, which can make the spheroidized structure more uniform, increase the spheroidization rate, improve product quality, and shorten the production cycle by half.

Chemical element content (%)

Specification：1.00~42.00mm

Application areas: Applicable to the manufacture of a variety of springs, such as leaf springs with medium loads, spiral springs with a diameter of 7-20mm, spring washers, spring rings, etc.; can also be used to manufacture high wear-resistant parts, such as grinder spindles, spring chucks, precision machine tool screws, cutters, etc.;
widely used in automobiles, machinery, aerospace and other fields.

Mechanical properties:

-Tensile strength σb≥1570MPa (quenched and tempered state), reflects the ability of the material to resist fracture during stretching.

-Yield point σs≥1375MPa (quenched and tempered state), indicating the stress when the material begins to produce obvious plastic deformation.

-Elongation after fracture δ≥5% (quenched and tempered state), reflects the degree of plastic deformation of the material after fracture.

-Shrinkage of area ψ≥20% (quenched and tempered state), indicating the degree of shrinkage of the cross section of the material when it breaks.

-Hardness HBW≤321 (hot rolled state).
