Hardness Testing

The quality of Lutco’s Heat Treat process is verified on a lot by lot basis. For every load run our inspection process is as follows:

  1. A review of the load report to include time, temperature and carbon control for each level in the heat treat cycle.
  2. A part from each heat treat basket is checked for surface hardness on a Mitutoyo HR500 hardness tester. This tester is calibrated by an outside service bi-annually and is checked with a certified test block, ensuring your product will meet your requirements.
  3. In addition, the case depth of components is verified weekly for each furnace, or more often per agreement with customers on a load by load basis. This test is performed on a Mitutoyo HM200 microhardness tester. All readings are converted from Vickers indent geometry to Rockwell C scale. 20+ years of results gives us, and you high confidence in our Heat Treat process.
