摘　　要：对JT245耐大气腐蚀塔桅结构钢进行室内加速腐蚀试验、电化学腐蚀试验、室外大气曝晒腐蚀试验及钢的表面锈层分析。试验表明:JT245耐大气腐蚀塔桅结构钢板耐大气腐蚀性能达到CortenA钢的实物水平,是理想的耐大气腐蚀材料,各项技术指标均能满足塔桅钢结构的制作要求;它已应用于港口、电网建设等工程之中,有明显的社会效益和经济效益。The corrosion resistance of JT245 tower structural steel was tested through interior accelerated corrosion test, electrochemical corrosion test, outside atmospheric corrosion test and surface rusty scale analysis. The results show that the weather resistance of JT245 is as well as CortenA. JT245 steel is an excellent weather-resistant material and could be used to produce tower steel structure. JT245 steel has been applied in the haven and electricity net project, the social effects and economic effects are notable.
