【摘要】：通過加入微合金元素并與控軋控冷工藝相結(jié)合,開發(fā)出590 MPa建筑用低屈強(qiáng)比耐火鋼。結(jié)果表明,該鋼種屈服強(qiáng)度大于460 MPa,抗拉強(qiáng)度大于590 MPa,屈強(qiáng)比小于0.8,600℃的屈服強(qiáng)度大于室溫的2/3,能滿足590 MPa級(jí)建筑用低屈強(qiáng)比耐火鋼的力學(xué)性能要求。
[Abstract]:By adding microalloyed elements and combining with controlled rolling and controlled cooling process, 590 MPa refractory steel with low yield ratio for building has been developed. The results show that the yield strength of the steel with yield strength greater than 460 MPa, tensile strength greater than 0.8600 MPa, yield strength ratio less than 0.8600 鈩，
