【 摘 要 】

Galvanized steel has a long history as an effective and economical material for manufacturing electrical poles. The purpose of this work is to study the corrosion of the lower part of the electric poles which support the electrical distribution networks. Microstructure and Mechanical properties have been studied for two samples, (A) is plate carbon steel and (B) is pipe carbon steel which are used in manufacturing the electrical poles. Furthermore, samples (A', B') and (A", B") are used to study the corrosion rates in air and burred in soil respectively. Results of mechanical properties have shown the Vicker hardness for sample (A) is (206) and for sample (B) is (185.4). Chemical compositional analysis has confirmed the carbon wt% for samples (A) and (B) are (0.24%) and (0.30%) respectively, leading to find that the sample (A) is identical to the (plate - A537), while sample (B) is identical to the (pipe - API 5L-X46) in the international examination (ASTM) for plate and pipe - carbon steel. The Corrosion rates (C.R.) of samples under study were tested where the values are (0.33 MPY) for sample (A') and (0.39 MPY) for sample (B') while the values are (0.45 MPY) for both samples (A") and (B").
