A New High Tensile Steel for Structural Work

Until very recently the only quality of steel which could be used economically for structures of moderate size was the standard 28/33 tons per sq. in. mild steel. Special high tensile steels have hitherto been so expensive that they were useful only for those structures in which the saving in dead weight was of paramount importance. In the United States of America nickel steel and silicon steels have been extensively used for long span-bridges, but so far as the author is aware they have not been used for smaller structures in which there is no special incentive for the designer to reduce the dead load.
