摘　　要：济钢新开发的塔桅结构用JT245耐大气腐蚀钢板,是在钢中添加适量的Cu、P、Nb等合金元素,使金属表面生成致密、连续的含Cu、P、Nb等合金元素的非晶产物层,较好解决了钢材的耐大气腐蚀性能。JT245钢的物理性能测试、焊接工艺试验评定、室外大气曝晒等系列试验表明:JT245耐大气腐蚀钢板机械、焊接性能稳定、耐大气腐蚀性能良好,完全能满足塔桅钢结构的制作需要。The tower structural steel JT245 produced in Jinan Iron and Steel Ltd.Co.was developed by alloying addition Cu?P?Nb etc.Because of the alloying element, tight and continuous amorphous layer was formed on steel plate.As a result,the steel plate is of good corrosion-resisting atmosphere properties.The JT245 steel plate also has good mechanical property and weldability.The steel plate could meet the need of tower structure very well.
