A study on the application of steel manufactured TMCP with Nb-microalloyed on commercial ships and offshore platforms

Niobium Bearing Structural Steels

DSME has applied Nb-steel made by Thermo-Mechanical Control Process (TMCP) on commercial ships and offshore structures widely. Especially, by adding the Nb to EH40, steel for thick plate applied on torsion box in container ship, E grade steel for LNGC and API 2W Gr50 for offshore structures required CTOD property, DSME could attain good weldability and the resistance for crack with Nb-microalloyed steel plates.
