| description | FIELD: metallurgy.SUBSTANCE: invention relates to high-strength multiphase steel with minimum tear resistance of 580 MPa mainly with two-phase structure for cold- or hot-rolled steel strip with improved formability, in particular for production of lightweight constructions for vehicles, consisting of elements by wt %: C 0.075 to ≤0.105; Si 0.200 to ≤0.300; Mn 1.000 to ≤2.000; Cr 0.280 to ≤0.480; Al 0.010 to ≤0.060; R≤0.020; Nb≥0.005 to ≤0.025; N≤0.0100; S≤0.0050; the rest is iron including usual steel accompanying elements not listed above.EFFECT: increased strength.16 cl, 9 dwg
Изобретение относится к высокопрочной многофазной стали с минимальной устойчивостью на разрыв 580 МПа преимущественно с двухфазной структурой для холодно- или горячекатаной стальной полосы с улучшенными формовочными свойствами, в частности для производства легковесных конструкций для транспортных средств, состоящей из элементов, мас. %: С 0,075 до ≤ 0,105; Si 0,200 до ≤ 0,300; Mn 1,000 до ≤ 2,000; Cr 0,280 до ≤ 0,480; Al 0,010 до ≤ 0,060; Р≤0,020; Nb≥0,005 до ≤ 0,025; N≤0,0100; S≤0,0050; остальное - железо, включая обычные сопутствующие стали не перечисленные выше элементы. Изобретение относится, кроме того, к способу изготовления холодно- или горячекатаной стальной полосы из этой стали. 4 н. и 12 з.п. ф-лы, 9 ил. |
