ASTM A131 Grade A, B, C and D Steel Work / Steel Structure / Steel Machining Parts

Date : 2015-06-24


ASTM A131 Grade A, B, C and D Steel Work / Steel Structure / Steel Machining Parts
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.
