The corrosion performance of hypo-eutectoid carbon steel, and alloy steel used in steam boilers at Al-Najibiyah Thermal Power Station in the Iraqi city of Basra was investigated. These metals were exposed to different media such as moisture and acids for (30, 45, and 60) days, then the rate of corrosion was calculated in a way of weight loss. The influence of carbon content, corrosive media and duration of immersion on samples of hypo-eutectic carbon steel and alloy steel were studied. The results showed an increase in the percentage of corrosion as a result of the increase in carbon content, and alloy steel has a high resistance to corrosion than carbon steel in the different corrosive media used in this study.

研究了伊拉克巴士拉市Al-Najibiyah热电站蒸汽锅炉中使用的亚共析碳钢和合金钢的腐蚀性能。这些金属暴露于不同的介质（如水分和酸）中（30、45 和 60 天），然后以重量损失的方式计算腐蚀速率。研究了含碳量、腐蚀介质和浸泡时间对亚共晶碳钢和合金钢试样的影响。结果表明，由于碳含量增加，腐蚀百分比增加，在本研究中使用的不同腐蚀介质中，合金钢比碳钢具有更高的耐腐蚀性。
