RINA Grade DH40 marine steel,RINA Grade DH40 shipbuilding steel plate,RINA DH40 steel plate,RINA Grade DH40 ship plate,RINA Grade DH40 marine steel plate are mainly used to build vessels which are sailing in low temperature oceans.When rolling RINA Grade DH40, TMCP or Normalized shall be done for heat treatment,and low temperature impacting test have to be done under minus 20 centigree.RINA Grade DH40 shipbuilding steel plate owned the highest tensile strength within 510-650 Mpa,and the minimum yield point shall be 390 Mpa.
For improve the thickness-direct steel property for shipbuilding steel plate RINA Grade DH40,Z-test for RINA Grade DH40 is also necessary,our customers can choose three different classes,Z15,Z25 and Z35.In China stated owned steel mills,just Xinsteel can roll RINA Grade DH40 shipbuilding steel plate with thickness above 100 millmeters.We can roll this steel grade RINA Grade DH40 reach to 350 millimeters.
