Key R & D field for high strength ship plate steel in resent years including low temperature toughness
excellent corrosion resistance
weldability with high heat input welding and antifatigue performance of steel has been summarized in article. The characteristics of research and development of new high strength ship plate steels and key technologies to produce typical high strength plate steel are presented. At present the trend of development of ship plate steels is to produce high strength-toughness
excellent corrosion resistance and manufacturing performance ship plate steel by using low C
high Mn
multicomponent microalloying technologies combining with control rolling-cooling and surface technologies.
