Abstract

Structural steel has been used in construction in the United States for more than 100 years. The material and its many products have undergone significant changes since the initial applications. Some of these were prompted by demands for higher strength and improved economies of construction, and many were caused by developments in joining techniques and fabrication. Increasingly complicated and demanding service and other environmental conditions have also been important. A brief review of some early steel developments is presented, but the major focus of the paper is today’s requirements for high performance steels, including the properties of tensile strength and stiffness, ductility, toughness, weldability and corrosion resistance. High-strength steels for tailor welded blanks (HSS-TWBs) refer to the stamping blanks or hydroforming tubular blanks that are made from parent blanks of dissimilar materials containing at least one HSS, or from the same HSS but with different thicknesses. HSS-TWBs have received great interest from manufacturing automotive bodies and other structural components where light weight is of primary consideration. The motivation to tailor a blank with dissimilar materials or thicknesses is to better distribute mass/weight and strength in a component, so that required structural functionalities (e.g. strength and safety, crashworthiness) can be better achieved at a reduced cost (by reducing the number of stamping parts and saving trimmed materials)
