the wire is already annealed when we get it after forming parts we send out to get heat treated. Heat treating is to take it up to 25-35 Rockwell. Their furnaces are gas batch furnaces. The parts are placed into basket sent through then
quenched. We are not ISO or QS but the heat treaters are.
Need some back up to present to customer that a 1 to 1.5% fallout from heat treating a wire formed part is acceptable.
Any help would be appreciated they are driving me crazy.
Thanks
