Metallurgical Laboratory

In addition to chemical analysis and mechanical tests, examination of the metallographic structure also provides valuable information about the material quality. Macroscopic and microscopic examinations, for example, can give information about casting defects, flow pattern after forging, rolling direction, inclusion content / cleanliness, type of structure (austenite/ferrite/bainite/martensite), grain size, amount of ferrite, depth of (de)carburisation, etc.

Hardness tests on microscopic scale make it possible to determine the hardness depth of case hardened layers, the hardness of small particles or the hardness of secondary phases in the microstructure.

Our laboratory is fully equipped for metallographic examinations using state of the art microscopes, micro and macro cameras and Vickers hardness testers. 

Our in-house machine shop prepares the test pieces for examination which allows for short lead times at competitive rates. Scroll down for a full list of the metallurgical tests our laboratory offers or contact us for more information.
