STEEL ARE ALLOYS OF IRON, WITH PROPERTIES DEPENDENT UPON THE TYPE AND AMOUNTS OF ALLOYING MATERIALS USED.<br />
THE SPECIFICATIONS OF SHIP BUILDING STEELS ARE LAID DOWN BY CLASSIFICATION SOCIETIES.<br />
SHIPBUILDING STEELS ARE TESTED AND GRADED BY CLASSIFICATION SOCIETY SURVEYORS WHO STAMP IT WITH APPROVAL MARKS<br />
