marine steel grade CCS Grade A is a general strength hull structural steel. CCS Grade A hot-rolled plates are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels. Our hot-rolled steel sheet has stable composition, uniform structure, few inclusions, good shape, and high dimensional accuracy. It has high strength, good toughness, easy processing and good weldability, and other excellent properties.
According to the minimum yield point of marine structural steel, the strength levels are divided into: general strength structural steel and high strength structural steel. Ship plate refers to the hot-rolled steel plate used to manufacture the hull structure produced in accordance with the requirements of the classification society construction code. The general strength structural steels of China Classification Society's standards are divided into: CCS Grade A, CCS Grade B, CCS Grade D, CCS Grade E four quality levels (ie CCSA, CCSB, CCSD, CCSE); the high strength structural steels of China Classification Society's standards are three Intensity level, four quality levels.
