The ship building steel CCSA(Hull structural steel) is divided to normal strength and high strength structural steel according to strength grade. Society. The normal strength structural steel has four quality grades as A, B, D, E according to the Classification Society standard rules and the high strength structural steel has three strength grades and four quality grades.
