摘要
对输电铁塔常用的不同厂家生产的4．8～10．9级普通螺栓和热镀锌螺栓进行了化学成分、显微组织及力学性能的比较试验。分析试验结果表明：热镀锌对各强度级别螺栓的力学性能基本没有影响。
According to the results of chemical composition, microstructure and mechanical property experiments, the mechanical property of general holt and hot-galvanizing bolt were compared with each other. The results showed that there was little effect of hot-galvanizing on bolt of grade from 4. 8 to 10. 9.
