| description | The invention relates to a hot-rolled ribbed bar for sleeve inspection and a production method, and belongs to the technical field of hot-rolled ribbed bar production in the metallurgical industry. According to the technical scheme, the steel bar comprises the following chemical components in percentage by weight: 0.24%-0.28% of C, 0.4%-0.8% of Si, 1.40%-1.60% of Mn, 0.43%-0.50% of V, 0.015%-0.020% of Ni, 0.20%-0.40% of Mo, 0.03%-0.08% of Cr, 0.03%-0.05% of V, less than or equal to 0.030% of P, less than or equal to 0.015% of S, 0.010%-0.012% of N, less than or equal to 0.01% of As, less than or equal to 0.01% of Sb, less than or equal to 0.005% of O, less than or equal to 0.0001% of H and the balance of Fe and inevitable impurities. The method has the beneficial effect that the mechanical property of the hot-rolled steel bar for sleeve detection can be guaranteed.
