Evaluation of High-Strength Steels Produced by Advanced Metallurical Processes (The National Shipbuilding Research Program)

Abstract

Newly developed high-strength steels produced by advanced steelmaking techniques and thermomechanical processing are shown to have toughness and weldability superior to those of conventionally heat treated, quenched and tempered steels. The above was confirmed by small-scale toughness testing and by controlled thermal severity testing to determine heat-affected zone cracking susceptibility. Small-scale testing of shielded metal arc weldments was also conducted. In view of their superior toughness and weldability these newly developed high strength steels should be useful for applications such as low temperature ship service, offshore structure service especially in harsh environments, and as a potential replacement for HY80/100 steels.
