Shipbuilding Steel Plate CCS Grade E
CCS Grade E material is a hot rolled normal tensile strength steel.CCS Grade E shipbuilding steel plate has a yield strength of 34,100 psi (235 MPa) and an ultimate tensile strength of 58,000 - 75,500 psi (400 - 520 MPa).CCS shipbuilding steels are available in four grades of normal strength steels, of which CCS Grade E is the highest.
CCS E grade shipbuilding steel has good toughness, corrosion resistance, good workability and weldability. Equal thickness and the following 40mm CCS E grade marine steel plate commonly used rolling state is empty rolling and control rolling. For CCS E marine steel plate with thickness more than 40mm, it should be normalized or TMCP heat treatment to improve the strength of CCS E marine steel plate.
