Sumitomo Steel Wire's - Oil Tempered Wire for Engine Valve Spring

The production process of oil tempered wire consists of drawing, heating to above autenitizing temperature and quenching into oil or equivalent quenchant, so that fine tempered martensite having high fatigue strength and enough ductility is obtained.
Our oil tempered is using super clean steel to minimize the risk due to non metallic inclusion. Since the state of the art technologies and well established quality management system are applied, our oil tempered wire shows outstanding performance and has good reputations among global customers.

Instructions

Since 0il tempered wire is susceptible to hydrogen brittleness and delayed fracture, please observe the following instructions.

Tempering shall be applied immediately after coiling.
Pickling nor plating shall not be applied.
The wire shall not be used under corrosive environment.
