What is CCS grade B marine steel ship plate

CCS grade B marine steel ship plate is the common tensile strength steel. CCS grade B marine steel ship plate has good toughness properties, strong corrosion-resistance, good processing properties and welding properties. The air rolled and control rolled are common rolling states for CCS grade B marine steel ship plate with equal and below 40mm thickness. And for CCS grade B marine steel ship plate whose thickness above 40mm, the heat treatment shall be Normalized or TMCP, so as to improve the strength of CCS grade B marine steel ship plate.

CCS grade B marine steel ship plate chemical composition:

Crack Sensitivity: PCM = (C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B)%
Carbon Equivalent: CEQ = [C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15]%
