2019 Spring Conference Session Spotlight

PCMI Session Spotlight

Araz Ardehali Barani and Thomas Wegler from Zapp Precision Metals will present “The Effect of Alloying Elements in Stainless Steel on Smut Formation” at the Spring 2019 International Technical Conference.

Araz Ardehali Barani and Thomas Wegler from Zapp Precision Metals will present “The Effect of Alloying Elements in Stainless Steel on Smut Formation” at the Spring 2019 International Technical Conference.

Smut is a deposit that is observed under certain conditions on the surface of an etched stainless steel. If the deposit dries on the surface it is almost impossible to remove it. Various stainless steel grades used typically in the PCMI were etched under same conditions. They were compared with respect to smut formation. If smut was present, its composition was analysed. From the comparison the effect of different alloying elements on smut formations is deduced. The results could help to select the appropriate material for a special application and at the same time reduce costs for the PCMI company.


Our Speakers

Araz Ardehali Barani

After studying material science at the technical university of Darmstadt, Araz Ardehali Barani started his career in 1999 at Fairchild Dornier Aerospace. From 2001 onwards he was responsible for the selection of the metallic materials used in the body of the aircrafts and the process development. In 2002 he joined the Max-Planck-Institute für Eisenforschung and worked on the optimization of silicon chromium martensitic steel used in the automotive industry. The results are summarized in the doctoral thesis (PhD at Technical University of Aachen) that was as awarded by the German steel association.

In 2006 Araz moved to the research and development department of ThyssenKrupp Nirosta. In 2008 he moved into the melt shop production and from 2009 responsible for the quality and development of both stainless steel melt shops in Bochum and Krefeld.

Since 2015, Araz has worked for Zapp Precision Metals and is responsible for the quality and development of the Precision Strip business division in Germany.
