High Tensile Steels

High Tensile Steels are special constructional steels which develop high yield, tensile and fatigue strengths, as well as excellent toughness when subjected to a quenching and tempering. (Supplied in the hardened and tempered condition)

The main criteria governing material choice are obtainable strength and toughness as a function of cross section, and full quenching and tempering properties, i.e. uniformity of mechanical properties over the full cross section.

The strength level is largely determined by the carbon content, whereas toughness, capability of being fully quenched and tempered, and the ratio of yield strength to tensile depend on the alloy content.
