CCS DH36 is a high-strength, normalized shipbuilding steel plate grade from Classifications of China (CCS), known for its good low-temperature toughness, excellent welding properties, and use in demanding marine applications like offshore platforms and the hulls of ships, including large carriers. It has a minimum yield strength of 355 MPa and a tensile strength range of 490-620 MPa.
