Marine Steel Specifications & FAQs

ASTM A131 Grade DH36: Uses and Properties

What is ASTM A131 DH36 used for? DH36 is a high-strength structural steel primarily used in the construction of ships, hulls, decks, and offshore marine structures requiring exceptional durability and low-temperature impact resistance.

ASTM A131 Grade AH36: High-Strength Marine Steel

What are the benefits of AH36 steel? As a low-alloy, high-strength structural steel plate for shipbuilding, AH36 offers excellent weldability, superior toughness, and corrosion resistance crucial for marine structural integrity.

EN 10225 Grade S355G2: Offshore Structure Plate

Offering excellent weldability under normalized conditions (+N), S355G2 is engineered for fixed offshore structures, topsides, and subsea jackets operating in harsh marine environments.
