A method for processing a hot formed, high-tensile-strength steel having an ultimate tensile strength (UTS) of at least about 730 MPa (105 ksi) and excellent toughness to retain essentially all the strength and toughness is provided. This processing is needed for the fabrication of high strength fittings that are used in the construction of linepipe for transport of natural gas, crude oil, as well as other applications. Furthermore, the hot formed high strength steel may be weldable with a Pcm of less than or equal to 0.35.
