ASTM A131 Grade E Shipbuilding Steel Marine Steel Plate/Coil

ASTM A131 Grade E steel Description

ASTM A131 Grade E shipbuilding steel plates are classified into general strength hull structural steel with the minimum yield point of 34 ksi [235 Mpa], , which is almost exclusively applied in the shipbuilding industry. ASTM A131 Grade E marine grade steel plates are usually supplied in normalized, or termo-mechanical control processed condition with EN 10204 3.2 MTC.

ASTM A131 standard hull steel plates refers to the hot-rolled steel plate used to manufacture the hull structure produced in accordance with the requirements of the classification society's construction rules. The general-strength structural steels in the standards of China Classification Society are divided into four quality grades: A, B, D, and E (i.e. CCSA, CCSB, CCSD, CCSE); the high-strength structural steels in the standards of China Classification Society are three Intensity levels, four quality levels. Grade A is boiling steel, B satin is killed steel, grade D and E are fully killed fine grain (aluminum treatment) steel, the manganese content in grade E steel is higher than that of D grade steel and the carbon content is lower than D grade steel steel.

ASTM A131 Grade E Shipbuilding and Offshore Platform Steel Plate/Coil is widely used in the welding of small and medium-sized ships. ASTM A131 Grade E marine steel has high strength, good corrosion resistance, welding performance, processing and forming performance and surface quality.

ASTM A131 Grade E 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】%
