Abstract

This study investigates the surface characteristics of low carbon steel SA210 Grade A following sandblasting with steel grit Al₂O₃. The sandblasting process is conducted at a fixed nozzle pressure of 5-7 bars and pressure angle of 45°, and blasting durations of 2,4,6,8 and 10 minutes. Mass reduction, thickness, hardness tests and microstructure analysis are carried out to determine the optimum blasting time. The most significant acceleration of the rate of mass decrease occurred at 0-2 minutes by 0.10 g and 4-8 minutes by 0.16 g. The most significant acceleration of thickness reduction rate occurred at minute 0-2 by 0.05 mm. The increase in hardness of the samples tested on the fire side showed an increase in hardness, at minutes 0-2 experienced the most significant increase in hardness from 133.14 HV to 138.95 HV, an increase of 4.19%. The surface treated with blasting microstructure experienced an increase in roughness. Based on the results, it can be concluded that extending the duration of the sandblasting process significantly influences the mass, thickness, and hardness of SA210 Grade A material.
