研究了几种锅炉炉管钢在 p H=3的 H2 SO4 溶液中腐蚀速率的差异 .电化学测试结果表明 :炉管钢的腐蚀速率与钢中合金元素的种类和含量有一定关系 ;含铬、钼量较高的钢种腐蚀速率较低 .由此可见 ,铬元素是抑制炉管钢在酸性介质中发生腐蚀的最主要的合金元素 ,其他元素如钼、镍等对炉管钢的腐蚀性能也有重要影响
The corrosion rates of several boiler tubes in H2 SO4 solution with p H = 3 were studied.The results of electrochemical tests showed that the corrosion rate of the tubes is related to the type and content of alloying elements in the steel, , The higher the molybdenum content of the lower the corrosion rate of the steel.Thus, chromium is to inhibit the corrosion of furnace tube steel in acid medium, the most important alloying elements, other elements such as molybdenum, nickel, etc. on the furnace tube corrosion Performance also has important implications
