November 26, 2022
*Induction Tempered spring steel wire usd for manufacturing springs, like suspensions in two- and four-wheel vehicles, emergency brake for large-sized vehicles, shutter,industrial machine
and other springs need high fatigue resistance and high sag resistance.
*Use the Wire rod of SAE9254 mainly and other similar grade added special elements
*Process such as descaling, drawing,quenching and tempering the wire is heat-treated to provide the required mechanical properties and iscontinuously inspected by eddy current flaw detector.
