a131 grade b shipbuilding plates Products Details
Marine steel plate is structural steel used in shipbuilding. It is considered a marine steel and must be able to withstand the corrosive effects that are common in water environments. While most carbon steels are not suitable for marine environments, there are several marine-grade carbon steels that have been approved by different associations for use in shipbuilding.
Hull structural steels are categorized into different strength classes based on their minimum yield strength: normal strength structural steels and high strength structural steels. Maine steel plates are hot rolled steel plates produced in accordance with the requirements of classification societies for the construction of hull structures. General Strength Structural Steel from China Classification Society is categorized into four quality grades: A B D and E.
ASTM A131 is a structural grade of steel plate used almost exclusively in shipbuilding. This grade is defined as normal strength with a specified minimum yield strength of 34 KSI (235 Mpa). Applications include barge, marine equipment and ship construction. These grades are also certified by the American Bureau of Shipping (ABS).
