In the study, various moulding and gating system designs have been designed for steel castings in the ÇİMSATAŞ foundry and the effects of the metal turbulence on hydrogen-induced crack defects have been investigated. The flow and solidification of the casting part were simulated by using Novacast flow and solidification program. The study clearly shows that metal turbulence has revealed that it plays a significant role in preventing hydrogen-induced crack defects in steel castings.
