FH36 Shipbuilding Steel Plate 2mm

The specific performance parameters are as follows:

- Chemical composition: The carbon (C) content is ≤ 0.16%, the silicon (Si) content is ≤ 0.5%, the manganese (Mn) content ranges from 0.90 to 1.60%, the phosphorus (P) content is ≤ 0.020%, the sulfur (S) content is ≤ 0.020%, the copper (Cu) content is ≤ 0.35%, the chromium (Cr) content is ≤ 0.020%, the nickel (Ni) content is ≤ 0.80%, the niobium (Nb) content ranges from 0.02 to 0.05%, the vanadium (V) content ranges from 0.05 to 0.10%, the titanium (Ti) content is ≤ 0.02%, the molybdenum (Mo) content is ≤ 0.08%, the nitrogen (N) content is 0.009%, and the acid-soluble aluminium (Als) content is ≥ 0.015%.
- Mechanical properties: The yield strength (ReH) is ≥ 355 MPa, the tensile strength (Rm) ranges from 490 to 630 MPa, and the elongation after fracture (A5) is ≥ 21%. At an impact test temperature of -60°C, the impact absorption energy (KV2/J) varies for different thicknesses. When the thickness is no greater than 50mm, the longitudinal impact absorption energy is ≥ 34J and the transverse is ≥ 24J. When the thickness is greater than 50mm and no greater than 70mm, the longitudinal is ≥ 41J and the transverse is ≥ 27J. When the thickness is greater than 70mm and no greater than 100mm, the longitudinal is ≥ 50J and the transverse is ≥ 34J.

In addition, the standard implemented for FH36 ship plate is GB712-2000, and it is typically delivered in the normalized state. It has been certified by nine classification societies and can be utilized in shipbuilding, ship supporting systems, hull shell manufacturing, internal ship components, ship maintenance, marine lifting equipment, deck machinery, as well as offshore oil platforms, marine structures, and other fields.
