High strength steel behaviour during hot dip galvanizing
Present study focuses on investigating the hydrogen diffusion during the hot dip galvanizing. This leads to understanding the cause of hydrogen embrittlement of high strength steels during the galvanizing process. In addition the mechanical properties of high strength steels before and after hot dip galvanizing were observed.A batch type hot dip galvanizing process was used and zinc bath temperature was 450 ℃. The bath consisted of 99.3 wt. ％ Zn and Al, Bi, Fe, Ni, Sn, Pb in balance. Substrate materials were chosen with similar thickness but from different grades of steels (S700 MC, Ruuki Optim 650 MC, C60 E and C35). In case of C60 E and C35 laboratory heat treatment was used (quenching and tempering). Result of the study show the behaviour of high strength steel during hot dip galvanizing process.
