Heat treatment

Spring, the spring should be tempered between 380 ℃ ~ 420 ℃ treatment to reduce surface stress, shot blasting should be 250 ℃ hot pressure or eliminate the stress treatment.

delivery status

The wire is delivered in coil form

Oil quenched - Tempered spring steel wire

Suitable for general purpose springs, brake brakes springs, middle and high grade automobile clutch springs, shock absorber coil springs, belt tensioner springs and steel wire for manufacturing engine valve springs.
