Abstract

The primary objective of this study is to validate the mechanical properties of ASTM A106Gr B carbon steel through a simulation process. This involves examining the stress values of the steel samples before and after undergoing the hot dip galvanizing (HDG) process, the commercial software Solidworks 2018 for a finite element analysis (FEA) was employed. Additionally, the study also investigates the electrical properties, low impedance ohmmeter was used to measure resistivity, of the samples that have been immersed in a hot zinc bath for varying durations of 3, 5, and 8 minutes. It has been found the results of a numerical analysis demonstrated a satisfactory agreement between the galvanized and non-galvanized samples. The stress values were found closely aligned, with an error rate of 1% in relation to the experimental results. Regarding the electrical aspect, the practical tests revealed that an increase in the thickness of the zinc material on galvanized samples led to a decrease in resistivity. Conversely, the electrical conductivity exhibited an upward trend with increasing immersion time and zinc material thickness.
