摘要
研究了添加0.15Mo+B和0.3Mo建筑用钢的抗震和耐火性能。结果表明,0.15Mo+B钢的先共析铁素体含量少于0.3Mo钢,使得0.15Mo+B钢的强度整体高于0.3Mo钢。但是,0.3Mo钢的强韧性搭配较好,能够更好的满足耐火的性能要求。
The seismic property and fire resistance of the construction steels with the addition of 0.15Mo＋B or 0.3Mo were investigated. The results show that the amount of proeutectoid ferrite of the 0.15Mo＋B steel is less than that of 0.3Mo steel,resulting in that the strength of the 0.15Mo＋B steel is higher than that of the 0.3Mo steel. While the strength and toughness combination of the 0.3Mo steel is better, and the steel can meet the requirements of the fire resistant.
