RINA EH32 Shipbuilding Steel Plate

RINA EH32 shipbuilding steel plate is a high-strength steel plate certified by the Italian classification society RINA (Registro Italiano Navale) and is widely used in shipbuilding and offshore structures. Here are its main features:

Mechanical properties:

Yield strength: The yield strength of RINA EH32 is typically at least 315 MPa. This indicates that the steel can bear a certain load without permanent deformation up to this stress level24.

Tensile strength: The tensile strength is in the range of 440 to 590 MPa. This high tensile strength enables the steel to resist strong pulling forces, making it suitable for use in the construction of large and heavy ships.

Elongation: It generally has a certain elongation rate, which shows good ductility and formability, facilitating the processing and shaping of the steel4.

ABS grade high-strength quenched and tempered steel plate

Level: Divided into 6 yield strength levels: 420, 460, 500, 550, 620, 690N/mm43, 47, 51, 56, 63, and 70kgf/mm?, 61, 67, 73, 80, 90, and 100ksi)

For each strength level, four levels of AQ, DQ, EQ, and FQ are specified based on the impact test temperature of Henan Steel's Charpy V-notch.

AQ43, AQ47, AQ51, AQ56, AQ63, AQ70

DQ43, DQ47, DQ51, DQ56, DQ63, DQ70

EQ43, EQ47, EQ51, EQ56, EQ63, EQ70

FQ43, FQ47, FQ51, FQ56, FQ63, FQ70

 

 

 

Impact resistance: It has good impact resistance, which is crucial for withstanding the harsh marine environment and various impacts at sea4.

Chemical composition: The chemical composition of RINA EH32 steel includes carbon (C) ≤ 0.18, silicon (Si) ≤ 0.50, manganese (Mn) 0.9 - 1.6, phosphorus (P) ≤ 0.035, sulfur (S) ≤ 0.035, and aluminum (Al) ≥ 0.0155. The specific content of each element is strictly controlled to ensure the steel's performance and quality.
