EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

For the present investigation, the same steel grade has been produced with two different deoxidation practices namely Al and Al-Si killing. There has been reported that deoxidation with Si reduces costs and decreases castability issues associated with Al. Material from both practices has been characterised in the "as cast" and "forged and rolled" conditions. The differences in terms of inclusion content and subsequent processing have been evaluated using different techniques (Optical Microscopy, Scanning Electron Microscopy and Automated Inclusion Analysis) and industrial standards (ASTM E45 and Ultrasonic MIDAS Testing) and the results will be reported.
