Steel section having a thickness of at least 100mm and method of manufacturing the same
The invention deals with a steel section, comprising a web central portion connected on each side to a flange portion having a thickness of at least 100mm, such steel section having a composition comprising, in weight percentage: 0.06 - 0.16 % of C, 1.10 - 2.00 % of Mn, 0.10 - 0.40 % of Si, 0.001 - 0. 50 % of Cu, 0.001 - 0.30 % of Ni, 0.001 - 0. 50 % of Cr, 0.001 - 0.20 % of Mo, 0.06 - 0.12 % of V, 0.0050% - 0.0200 % of N, not more than 0.040 % of Al, not more than 0.040 % of P, and not more than 0.030 % of S, and comprising optionally one or more of the following elements, in weight percentage: less than 0.005 % of Ti, and not more than 0.05 % of Nb, with the reminder being iron and impurities resulting from elaboration, and said steel section microstructure including at least one kind ofvanadium precipitates possibly comprising also one or more metal chosen among chromium, manganese and iron, said precipitates being chosen among nitrides, carbides, carbo-nitrides or any combinationof them, more than 70% of such precipitates having a mean diameter below 6 nm. The invention also deals with a manufacturing method thereof.
本发明涉及型钢，其包括在每一侧连接至厚度为至少100mm的翼缘部分的腹板中央部分，这样的型钢具有按重量百分比计包含以下的组成：C：0.06％‑0.16％、Mn：1.10％‑2.00％、Si：0.10％‑0.40％、Cu：0.001％‑0.50％、Ni：0.001％‑0.30％、Cr：0.001％‑0.50％、Mo：0.001％‑0.20％、V：0.06％‑0.12％、N：0.0050％‑0.0200％、Al≤0.040％、P≤0.040％、S≤0.030％，并且按重量百分比计任选地包含以下元素中的一者或更多者：Ti<0.005％、Nb≤0.05％，剩余部分为铁和由细化产生的杂质，并且所述型钢的显微组织包含至少一种可能还含有选自铬、锰和铁的一种或更多种金属的钒析出物，所述析出物选自氮化物、碳化物、碳‑氮化物或它们的任意组合，大于70％的这样的析出物的平均直径小于6nm。本发明还涉及其制造方法。
