Heat Treatment

Thanks to the more than thirty years experience in the aeronautics world,  Umbra is able to provide a professional service as a supplier for a wide range of heat and thermo-chemical treatments for steels.

Since 2006 the NADCAP qualification (achieving MERIT status in 2011) provides further proof of the high technical-quality standard.
All our heat treatment systems are certified for pyrometry according to international standard AMS 2750; some of them are also certified for customer specification BAC 5621.


We are therefore in  a position to carry out certified treatments for:
