Abstract

The low carbon steel (ASTMA106 Gr B) has been used in this study to find out the effect of the hot dip galvanizing process on the mechanical properties and hardness. The tests were conducted at ambient temperature, and a microscopic, scanning electron microscope SEM and energy-dispersive X-ray spectroscopy EDS were examined before and after coating. The samples of the tensile test were prepared according to the ASTM (E8/E8M − 16). This study aims to increase the knowledge of the effect of HDG on the mechanical and hardness of the pipe steel, to prevent corrosion in pipes. There has been a slight decrease in the yield stress, and the ultimate stress), while % of elongation increased slightly. There has been a uniform distribution of hardness on the coated surfaces compared to the uncoated surface. The coated surface with a zinc layer is 250µm. There have been examine the chemical composition of zinc element is 96.4wt%. The coating with HDG has a nice layer of protection without any soup reduction in the mechanical properties.
