The higher steel grade CCS Grade DH40 shipbuilding steel plate 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 DH40 can bear the higher strength and used to some steel structure parts in ships.Normalised heat treatment and low temperature impacting test shall be done for CCS Grade DH40 shipbuilding steel plate.
At current,Xinsteel is cooperating with Wuyang steel mill about starting rolling the heavy shipbuilding steel plate CCS Grade DH40 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.Want to get the valued price for shipbuilding steel plate CCS Grade DH40,please inquiry Xinsteel now.
