ASTM A131 tensile test on steel for ships cover structural steel plates, shapes, bars, and rivets for use in ship construction. Materials under the ASTM A131 specification can be categorized as ordinary strength and higher strength. ASTM A131 pertains to materials that shall conform to the required metallurgical structure which shall be evaluated by determining the average grain size. Mechanical properties such as elongation and toughness shall be evaluated using tension test and Charpy V-notch impact test. ASTM A131 includes specifications on shapes and bars normally available as Grades A, AH32, and AH36. The maximum thickness of products furnished under the ASTM A131 specification is 4 in. or 100 mm for plates and 2 in. or 50 mm for shapes and bars. When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized in addition to the ASTM A131 tensile test.
