According to the minimum yield point,the strength level for shipbuilding steel grades are divided into general strength structure steel and high strength structure steel. ASTM A131 Grade A, B, C and D Steel machining parts is fabricated by the general strength steel material. The classification society for ASTM A131 Grade A, B, C and D steel work can be ABS, LR, DNV, BV, GL, CSS etc. The Grade A, B, C and D Steel Work usually is used in the manufacturing of the hull structure of the ship.
