What is material CCS Grade A?

CCS Grade A material is a quality grade of shipbuilding steel. According to the general strength structural steel of China Classification Society Standards, the ordinary strength ship steel plate grade is divided into four quality grades: A, B, D, and E (ie, CCSA, CCSB, CCSD, CCSE); CCS Grade A is a ship of A grade ship steel material.

Due to the harsh working environment of the ship, the hull is subject to chemical corrosion, electrochemical corrosion, sea creatures and microorganisms; the hull is subject to large wind waves and alternating loads; the shape of the ship makes its processing methods complicated and other factors. The steel used for hull structure is strict. First of all, good toughness is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

BBN Group can produce CCS Grade A hot-rolled steel plates used for manufacturing hull structures produced in accordance with the requirements of classification society.
