Marine ABS grade A steel is a kind of hot rolled general tensile strength steel. ABS steels come 4 grades in ordinary-strength steel for shipbuilding and grade A is the lowest one of them. The Marine ABS A plates have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa). All the marine ABS grade A shipbuilding steel offered by Katalor Industry can be certificated by American Bureau of Shipping(ABS).
Marine ABS Grade A Steel Properties
Tensile Strength, ksi [MP]: 58 TO 75 [400 to 520]
Yeild Point, minksi [MP]: 34 [235]
Elongation in 8 in. [200 mm], min %: 21
Elongation in 2 in. [50 mm]B, min %: 24
Marine ABS Grade A Hot Rolled Plate Specification
Steel Standard:ABS (American Bureau of Shipping)
Rolling Type:Shipbuilding steel plate, high strength ship steel plate
Thickness:3mm-280mm
Width:1200mm-4200mm
Length:3000mm-18000mm
Heat Treatment:As Rolled/Control-rolled/TMCP/Normalised
Marine ABS Grade A steel plates with the thickness equal and belows 40mm, and for thickness above 40mm,the heat treatment shall be Normalized or TMCP, these two technical treatment would improve ABS Grade A steel strength in yield and tensile points.
