Microstructure and Properties of High Performance Steels by Controlled Rolling

High performancesteels (HPS) require low yield ratio, high uniform elongation and high low temperature impact toughness in addition to higher strength. In this paper,experimental steelswere produced by controlled rolling and tempering to meet high performance requirements. Itwasconcluded that experimental steels by controlled rolling and tempering had similar performance with quenched and tempered steel (QT).
