Rockwell check Iron (castings) in a heat-treated state
Gentlemen, I am the Quality Manager of Riviera Tool Company, manufacturer of large scale complex stamping dies.
We are instructed by GM to Rockwell check Iron (castings) in a heat-treated state. What we are encountering is . . . We do not have IRON standard test blocks for calibration. Could you provide direction where to purchase these blocks ... or ... provide information regarding a conversion chart i.e., Rockwell C to Leebs. We are currently using a Krautkramer dynamic tester. Your response is greatly appreciated at your earliest convience!
