研究添加不同微合金元素对建筑钢筋力学性能的影响,分析表明,在20MnS i中添加质量分数0.08%~0.10%的钒和0.04%~0.07%的钛,可使钢筋的屈服强度达到530 MPa以上,抗拉强度达到650 MPa以上。
The effects of adding different microalloying elements on the mechanical properties of building rebar were analyzed. The results showed that the addition of 20% vanadium and 0.04% ~ 0.07% titanium in mass fraction of 20MnS i can make the yield strength of rebar reach 530 MPa , Tensile strength of 650 MPa or more.
