摘要：
本发明涉及一种高强度抗震钢筋及其生产方法，所述高强度抗震钢筋按照重量百分比的成分组成如下：C 0.15～0.25%，Si 0.2～0.4%，Mn 0.3～0.45%，N 0.03～0.05%，Cr 0.08～0.09%，V 0.12～0.21%， Ta 0.009～0.015%， S ≤0.008%，Sr 0.008%～0.009%，P ≤0.01%,余量为Fe及不可避免的杂质。本发明制备的钢筋，Rm:850-876MPa，Rel:608-620MPa，A5:17.9-18.9，强度高，完全能够满足高强度抗震钢筋的要求。
摘要（英）：

The invention relates to a high-strength and anti-seismic reinforcing steel bar and a production method thereof. The high-strength and anti-seismic reinforcing steel bar comprises components in percentage by weight as follows: 0.15%-0.25% of C, 0.2%-0.4% of Si, 0.3%-0.45% of Mn, 0.03%-0.05% of N, 0.08%-0.09% of Cr, 0.12%-0.21% of V, 0.009%-0.015% of Ta, smaller than or equal to 0.008% of S, 0.008%-0.009% of Sr, smaller than or equal to 0.01% of P and the balance of Fe and inevitable impurities. According to the prepared reinforcing steel bar, the Rm is 850-876 MPa, Rel is 608-620 MPa, A5 is 17.9-18.9, the strength is high, and requirements for the high-strength and anti-seismic reinforcing steel bar can be completely met.
