low temperature annealing
- Spring stainless steel plate can be used even as a temper rolled material but low temperature annealing (tempering) at around 400℃ after parts manufacturing is recommended when a stronger springiness is needed.
- Low temperature annealing conditions: Normally 1 to 2 hours heating at 400° to 420℃ (treating at 200° to 450℃ for a suitable amount of time is also possible depending on product performance, facilities, and work conditions).
