Microscopy Steel Analyses at Turkey’s Largest Galvanized Steel Producer

A long-term Test and Analysis Specialist at Borçelik shares their use of electron and optical microscopy on steel products

Through a joint venture with ArcelorMittal and Borusan, Borçelik is one of the largest galvanized steel producers of Turkey, offering some of the highest quality steel for the automotive, home appliances, construction and general metal industries.

Ömer Yıldırım is a seasoned Test and Analysis Specialist at Borçelik. For twenty-three years, he has worked with Borçelik in flat steel production processes and stages as well as defect analysis using both electron and optical microscopy. His work includes surface and cross-sectional analyses of hot rolled flat steel, cold rolled flat steel and coated flat steel, such as galvanized, enameled, and painted.

I investigate the reasons behind corrosion formation, identification of root causes behind defects and problems in flat steel processes. I also perform studies on new products in terms of R&D and innovation.

Microscopy in Steel Production

From R&D to Quality Control to Customer Support

Mr. Yıldırım spends most of his work day using the ZEISS Sigma 300 field emission scanning electron microscope and the ZEISS Axio Imager 2 optical microscope for various analyses. Microscopy is critical for him to obtain highly valuable data in order to:

  • Support all R&D and innovation studies
  • Identify raw material quality problems and determine the root cause of these problems
  • Respond to customer complaints by examining their process parameters to help them troubleshoot problems

We are able to avoid significant financial losses through product controls by identifying raw material problems and making use of the findings discovered during customer complaints.
