Product brief introduction:

60 si2mna steel grades, the high strength of materials, the elastic limit, showed, hardenability and resistance to tempering stability is good, use is very wide, usually for some of the work under high stress fatigue performance of important spring and wear serious spring, such as ring spring, shock absorber spring and brake spring, automobile, motorcycle, tractor spiral spring, cylinder valve spring and some mechanical with wear-resisting rods, etc.

Technical parameters of products:

Oil quenching - tempered spring wire

Note: The roundness is not greater than half the allowable deviation of the dimensions

Wire surface inspection

The wire surface is smooth and should not have any defects such as scratches, rust, folds, stalks and other defects that may cause harmful effects on the use of the wire, allowing the maximum depth not to exceed

The table specifies the depth of the defect. VD grade, TD grade wire shall not be fully decarburized, but allow partial decarburization of not more than d1.0%.  The maximum depth allowed for surface defects
