KR EQ63/KR E63 marine steel plates are a specialized grade of steel designed to meet the rigorous demands of the shipping industry. These plates possess exceptional mechanical properties, chemical composition, and undergo meticulous heat treatment processes to ensure durability and safety in marine environments.

The chemical composition of KR EQ63/KR E63 steel plates is carefully balanced, primarily consisting of carbon, silicon, manganese, phosphorus, and sulfur. The carbon content, in particular, contributes significantly to the steel's strength and hardness. Silicon and manganese further enhance the steel's strength and ductility, providing excellent resistance to corrosion and fatigue.

Mechanically, these steel plates exhibit remarkable tensile strength, yield strength, and elongation. Their yield strength hovers around 630MPa, while the tensile strength ranges from 700 to 850MPa. The elongation exceeds 16%, indicating good ductility. Additionally, KR EQ63/KR E63 steel plates maintain stable performance even in extremely cold temperatures, ensuring their reliability in harsh maritime conditions.

Heat treatment plays a crucial role in the production of these steel plates. Through controlled heating and cooling cycles, the steel achieves its desired mechanical properties and microstructure. This process helps refine the grain structure, eliminate internal defects, and improve the overall performance of the steel.

KR EQ63/KR E63 steel plates are available in various production sizes to cater to different shipbuilding requirements. The plates can be custom-cut to specific dimensions, ensuring seamless integration into the ship's structure.

Impact testing is a vital aspect of quality control for marine steel plates. KR EQ63/KR E63 steel plates undergo rigorous impact testing to assess their resistance to sudden loads and impact forces. These tests ensure that the steel plates can withstand the dynamic loads encountered in marine environments, such as wave impacts and collisions.

The primary applications of KR EQ63/KR E63 steel plates span across various sectors of the shipping industry. These plates are widely used in the construction of hulls, decks, and other critical structural components of ships. Their excellent strength, toughness, and corrosion resistance make them ideal for use in both commercial and military vessels.
