LOW CARBON HIGH STRENGTH STRUCTURAL STEELS--A STATUS REPORT

The Author discusses some of the salient features in the development and formability of low-carbon high-strength low-alloy (HSLA) steels. Some of the relevant implications of structure properties relationship studies are examined, and various developments in the field of controlled processing are described. The major impetus for development of HSLA steels has been provided by the need for higher strength and lighter sections; increased ductility, formability, and weldability; fracture resistance in terms of a low transition temperature and high shelf energy; and for maximum economic use of increasingly scarce raw materials. The applications in which HSLA steels are being used or envisaged are continually increasing. In structural engineering cold-formed sections are being substituted for hot-rolled products. Increased use of bent, formed, or punched members may be envisaged, and the use of stiffened tubular or monocoque assemblies which require the availability of formable, easily welded, flat-rolled products. In shipbuilding, the weight saving resulting from the use of HSLA steels is a clear advantage, but design stability and corrosion resistance may also be important. However, it is reported that utilization of these steels is some 10-25% of the hull steel weight for various types of cargo and tanker vessels. Order from: BSRA as No. 46,859.
