ABS-A American Bureau of Shipping Ship Plate, AB/A Ship Plate Specification, ABSA Marine Steel Plate

ABS-A is a ship board certified by the American Bureau of Shipping, ABS/A ship board is suitable for the manufacture of ship hull structures, docks, oil production platforms, offshore transmission pipelines, coastal power plants, dock facilities and other structural parts in ocean-bound, coastal and inland navigation areas.

General strength ship plates: A, B, D, E. High-strength shipboard: AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH36 and ultra-high-strength shipboard DH460, EH460, EH550, EH690, etc. Thickness: 3-80mm, width 1500-4000mm, length 4000-19000mm. Certified by the world's nine major classification societies (CCS, ABS, VL, LR, BV, NK, KR, RINA, RS).

The American Bureau of Shipping (abbreviated as ABS) is a non-profit classification society headquartered in Houston, Texas, USA.

Hull structural steel according to the quality of A, B, C, D four grades of the plate A, B grade steel plate belong to the general strength plate, the chemical composition of Mn content is very different, there is no other gap in mechanical properties, yield and tensile strength are the same, the difference is the experimental temperature of impact energy, grade A is 20 degrees, grade B is 0 degrees. Obviously, the B class is relatively better.
