How much is holding time and annealing temperature for a welded strip of 45x0.9 mm by Electric flash welding machine in welded zone?

11 November 2017 0 6K Report

We weld wood band saw of different width and thickness.

It is welded by Electric flash welding machine. the Hardness of strip is 44-46 HRC.

How much must be the temperature and Holding time of welded zone in order to decrease its hardness to 44-46 HRC. The strip steel Grade is C75S.
