| description | The invention discloses high thickness novel type hydrogen sulfide resistant steel and a production method thereof. The steel comprises the following chemical components by weight percentage: 0.17 to 0.20 percent of C, 0.30 to 0.40 percent of Si, 1.10 to 1.20 percent of Mn, less than or equal to 0.008 percent of P, less than or equal to 0.003 percent of S, 0.020 to 0.030 percent of Ni, 0.025 to 0.35 percent of Nb, and the rest of Fe and unavoidable impurities. The steel has the following advantages that: (1) the steel has purer quality with less than or equal to 0.008 percent of P and less than or equal to 0.003 percent of S; (2) the steel has good lamellar tearing resistance Z which is more than or equal to 36 percent in the full thickness direction; (3) the steel has good low temperature toughness at 50 DEG C below zero; and (4) the maximum thickness of the steel plate can reach 130mm. Test results show that the steel plate is characterized by higher purity, even constituents, and internal compactness; the |
