CCS Grade FH40 Marine steel CCS Grade FH40 shipbuilding steel CCS FH40 steel plate
The highest steel grade CCS Grade FH40 shipbuilding 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 CCS Grade FH40 can bear the higher strength and used to some steel structure parts in ships.At current,Gnee steel is cooperating with Wuyang steel mill about starting rolling the heavy shipbuilding steel plate CCS Grade FH40 with the unit weight about 30 tons.This rolling should be from steel ingots and normally the plate rolling yield should be above 72 percentage.

In China stated owned steel mills,just Gnee steel can roll CCS Grade FH32 shipbuilding steel plate with thickness above 100 millmeters.We can roll this steel grade CCS Grade FH32 reach to 350 millimeters.The chemical composition and mechnical property for CCS Grade FH32 thickness above 100 millimeter is according to the steel plate witht thickness equal to 100 millimeters.
