ASTM A131 Grade D Shipbuilding and Offshore Platform Steel Plate/Coil

ASTM A131 Grade D steel Description

ASTM A131 Grade D marine steel plates belong to general strength shipbuilding steel. The equivalent grades of ASTM A131 grade D steel are ABS D, BV D, CCS D, NV D, GL-D, RD, LR D, KD, RINA D, etc. ASTM A131 Grade D shipbuilding steel plates contain chemical elements that resist corrosion and decrease brittleness, especially in cold temperatures, and increase strength and toughness to resist vibration and force traumas.

ASTM A131 Grade D shipbuilding steel plates are used in the ship project and ocean offshore structural project, for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components. ASTM A131 Grade D hull steel plate shall do charpy V-notch test when the thickness is above 1/4 in. [6.4mm].

ASTM A131 Grade D steel Chemical composition

(heat analysis, % max unless otherwise specified)

Notes: The contents of nickel, chromium, molybdenum, and copper are to be determined and reported. When the amount does not exceed 0.02 %, these elements may be reported as≤0.02 % .

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】%

ASTM A131 Grade D steel Mechanical Properties

Notes: Impact tests are not required when the material is produced using fine grain practice and normalized.
