Abstract

PURPOSE:To inexpensively produce the title bolt with low temp. toughness by hot rolling steel of a specified compsn. contg. C, Si, Mn, Al and one or more out of Nb, V, Ti and Zr after which the wire rod is cooled at a specified rate, optionally subjected to skin pass drawing, and then cold formed.
