■ Overview
The highest steel grade KR Grade FH40,KR FH40,KR FH40 steel plate in normal shipbuilding steels are used abnormally owning to its high cost and substitutability.With the minimum yield point at 390 Mpa,and tensile strength within 510-650 Mpa,steel plate KR Grade FH40 can bear the higher strength and used to some steel structure parts in ships.
