DNV E36 is a high-strength shipbuilding steel plate that is certified by the classification society Det Norske Veritas (DNV). It has a minimum yield strength of 355 MPa and is primarily used for structural components in ships, offshore oil platforms, and other marine structures due to its good toughness, strength, and weldability.

Common applications
Shipbuilding: Hull structures, decks, and other main structural components for large vessels.
Offshore structures: Offshore oil drilling platforms and support structures.
Other marine equipment: Barges, smaller vessels, and various types of marine equipment.
Production and quality
Heat treatment: Plates are typically normalized or thermo-mechanically controlled processed, while shapes and bars are heat treated and rolled.
Certifications: DNV E36 steel is approved by various international classification societies, including DNV, ABS, LR, and BV.
Impact test: Impact tests are performed to ensure quality at low temperatures.
