An ultra-high strength, weldable, low alloy steel with excellent cryogenic temperature toughness in the base plate and in the heat affected zone when welded, having a tensile strength greater than 830 MPa (120 ksi) and a micro-laminate microstructure comprising austenite film layers and fine-grained martensite/lower bainite laths, is prepared by heating a steel slab comprising iron and specified weight percentages of some or all of the additives carbon, manganese, nickel, nitrogen, copper, chromium, molybdenum, silicon, niobium, vanadium, titanium, aluminum, and boron; reducing the slab to form plate in one or more passes in a temperature range in which austenite recrystallizes; finish rolling the plate in one or more passes in a temperature range below the austenite recrystallization temperature and above the Ar3 transformation temperature; quenching the finish rolled plate to a suitable Quench Stop Temperature; stopping the quenching; and either, for a period of time, holding the plate substantially isothermally at the QST or slow-cooling the plate before air cooling, or simply air cooling the plate to ambient temperature.
在基体板以及焊接时的热影响区处的低温韧性优异的超高强度、可焊接、低合金钢具有高于830MPa(120ksi)的抗拉强度,并且具有包含奥氏体薄膜层和细晶粒的马氏体/下贝氏体板条的显微层状组织,所述钢的制备过程为:加热含有铁以及特定重量百分比的添加元素的钢坯,所述添加元素为碳,锰,镍,氮,铜,铬,钼,硅,铌,钒,钛,铝,以及硼中的一些或全部;在奥氏体可发生再结晶的温度范围内,采用一个或多个道次,将所述钢坯轧制成板材;在低于奥氏体再结晶温度但高于Ar 3 转变点的温度下,采用一个或多个道次对所述板材进行终轧;将所述终轧板材淬火至一适当淬火终止温度;停止所述淬火;或者在空冷前在QST点基本等温保持所述板材一段时间,或者对所述板材进行缓慢冷却,或者只是简单地将所述板材空冷至室温。
