1.Applicaiton of oil tempered spring steel wire:
Oil-Quenching and Tempered spring steel wire which used for automobile and motorbike, for the production of engine valve,clutch spring,shock absorber spring.brakes, motorcycle shock absorber, and safe-belt spring.
2. Size of oil tempered spring steel wire: 0.8MM-16MM
3. Standard of oil tempered spring steel wire: JISG3560-94; GB18983-2003; EN102702: 2001 , EN10270-2 & ASTM-A229-GRADEⅠ& ASTM-A230 & ASTM-A231 & ASTM-A232 & ASTM-A401.etc
4. Certification: ISO/TS16949, ISO9001, SGS, CTI, ROHS,
5.The advantage of oil tempered spring steel wire
1).High yield ratio, small residual deformation of the spring.
2.)Stable performance: with the disc less than 75Mpa is conducive to coil spring and improve spring fatigue life.
3.) High yield of spring-winding, which will help reduce cost.
4. )Compared to tradition production methods, the oil tempered spring wire will reduce some working procedure.
