【摘要】：通过加入微合金元素并与控轧控冷工艺相结合,开发出590 MPa建筑用低屈强比耐火钢。结果表明,该钢种屈服强度大于460 MPa,抗拉强度大于590 MPa,屈强比小于0.8,600℃的屈服强度大于室温的2/3,能满足590 MPa级建筑用低屈强比耐火钢的力学性能要求。
[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，
