ABSTRACT:
High strength low alloy steels, produced as strip or the like by hot rolling, permit unusual economy of alloying ingredients while achieving superior mechanical properties, with a composition containing specifically low carbon and low manganese, and moderate proportions of both columbium and titanium, preferably with no requirement of silicon. Yield strengths in a range to and well above 80 ksi are attainable depending on the content of columbium and titanium, and good properties of formability are exhibited in the transverse direction. Processing conditions, for hot rolling and coiling, can be selected over reasonably convenient ranges of temperature conditions, while rolling load requirements are acceptable for products of various thicknesses. The steels are notably useful for thin strip, satisfying the usual mechanical property needs of such products with relatively low cost.
