    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.

Metallography

Inspection of the microstructure of a metal sample

Metallography

This is the inspection of the microstructure of a metal sample, e.g. for grain size determination or the measurement of case depth in a case hardened material.

Sample A shows the structure after heat treatment

Sample B shows a closer inspection of a fault site in the metal
