1.material:55CrSi,60Si2Mn,50CrV 2.specification:0.3mm-5.0mm. 3.heat Treatment:Oil-quenching and tempering 4.size:0.3mm-4.0mm
Induction heat characteristics of high-strength spring steel heat treatment:
1. Rapid heating rate and no decarburized zone due to heat treatment ,make our products have higher intensity.
2.The production line is a high-precision temperature control system. The steel wire heats stably, it is to ensure consistency of material properties.
3.As it has very mature and stable application of heat treatment, it is to increase product quality to a higher level.
