GL Grade B shipbuilding Steel Description:
GL grade B steel is a kind of hot rolled general tensile strength steel. The GL B grade steel plates have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa). GL steels come 4 grades in ordinary-strength steel for shipbuilding and grade B is one of them.
GL Grade B shipbuilding Steel Application:
GL B Shipbuilding steel plates can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components. GL B grades of steel plate are almost exclusively used in the Shipbuilding Industry for the construction of structural parts of ships, barges and marine equipment.
GL Grade B Steel Grade Specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
