ASTM A131 marine grade A ms steel plate is ordinary strength shipbuilding steel with a specified minimum yield point of 34 ksi [235 Mpa]. A131 marine grade A ms steel is usually in forms of structural steel plates, shapes and bars for use in ship construction. The min. thickness we can supply for ASTM A131 marine grade A ms steel plate with certificate is 3mm. The marine grade A ms steel plate is always certified by ABS, LR, BV, DNV GL, RINA, NK, CCS, KR, RMRS and so on classification societies as the end user’s requirements.
ASTM A131 marine grade A ms steel plate 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 % .
ASTM A131 marine grade A ms steel plate mechanical property:
||Charpy V Impact Test
|ASTM A131 grade A
Notes:Impact tests are not required when the material is produced using fine grain practice and normalized.
A131 marine grade A ms steel equivalent grades:
Charpy V-notch test shall be made on ASTM A131 marine grade A ms steel plate over 2 in. [50mm] in thickness. The marine grade A ms steel plate is mainly used in the shipbuilding industry for the construction of structural parts of ships, barges and marine equipment.
