... toughness and high yield strengths in the range of 345 to 620 MPa (50 to 90 ksi). This development of controlled-rolling processes coupled with alloy design has produced increasing yield strength levels accompanied by a gradual lowering of the carbon content. Many of the proprietary microalloyed HSLA steels...
