      • Testing

        The final step in processing is usually verification of the required hardness.

        We have a dedicated testing laboratory which contains calibrated hardness testers such as Rockwell C, Rockwell B, Vickers and Microvickers. We can also test for Chemical Composition, Microstructural Analysis and Tensile Strength.

        Vacuum Processing

        We employ the latest temperature recording and controlling equipment for accurate temperature measurement.

        Each furnace batch has temperature profile recording which is then stored and linked to each batch via our quality control database. Our standard vacuum is 5 x 10-2mBar with a 4 Bar Nitrogen quench but we can also offer high vacuum at 8 x 10-5mBar with Argon quenching.

        Case Hardening

        Our Ipsen sealed quench furnace has atmosphere control and recording of the carbon potential within the chamber.

        This allows for accurate and consistent control of case depth during carburising and the decarburising atmosphere for neutral hardening. Temperature and atmosphere results are recorded and can be linked to each individual furnace batch.
