Heat Treatment and Rolling Processes for CCS Grade E Shipbuilding Steel Plates
The performance of high-quality shipbuilding steel depends not only on its chemical composition; thermomechanical processing is equally crucial. For CCS Grade E shipbuilding steel plates, the rolling and heat treatment schemes determine whether they ultimately meet the impact toughness requirements at -40°C.

Key Differences Between CCS Grade E and Grade A, B and D Steel Plates
CCS Grades A, B, D and E are all normal-strength structural steel plates for shipbuilding, with a yield strength of ≥ 235 MPa. The main difference between the four grades lies in their progressively increasing low-temperature impact toughness; Grade A has the lowest requirement, whilst Grade E offers the best low-temperature performance and is consequently the most expensive.

The Application of CCS Grade D Shipbuilding Steel Plates in Civilian Vessels and Offshore Engineering
CCS Grade D shipbuilding steel plates are widely used in commercial vessels, inland waterway vessels and offshore engineering structures subject to medium to low loads, owing to their stable mechanical properties, good low-temperature toughness and cost-effectiveness. This article provides a detailed overview of the specific application areas, operational characteristics and engineering compatibility advantages of these steel plates in various engineering contexts.

Surface anti-corrosion treatment for CCS Grade D shipbuilding steel plates
The marine environment, with its high levels of salt spray, seawater and humid air, is highly conducive to the electrochemical corrosion of carbon steel. During prolonged service at sea, unprotected CCS Grade D steel plates are prone to surface rust, pitting and structural thinning, which not only shortens their service life but also jeopardises the safety of the vessel. Consequently, the standardised anti-corrosion treatment of Grade D steel plates prior to ship assembly is an essential part of the manufacturing process.
