55CrSi Oil-tempered Spring Steel Wire

The relatively good temperature and time of oil quench-tempering spring steel wire heat treatment is decided by the thickness of the wire diameter.As for the oil quench-tempering spring steel wire after winding within a few hours to stress tempering is not made rigid provisions, in general, the spring after winding should be within 12 hours to stress tempering.For springs made of hot coil and annealed material wound, the spring quenching and tempering interval should be completed within the specified time!Otherwise the consequence is very serious.
