Main features of DH36
High strength: DH36 steel has a high yield strength and tensile strength, can withstand greater external force and pressure, to ensure the stability and safety of ship structure.
Good toughness: the steel can also maintain good toughness at low temperatures, not easy to brittle fracture, suitable for ships sailing in cold waters.
Excellent weldability: DH36 steel has good weldability, easy to carry out various welding operations, and the quality of welded joints is stable.
Corrosion resistance: Although DH36 steel is mainly used for structural strength, it also has a certain corrosion resistance and can resist the erosion of seawater and other corrosive media to a certain extent.
Chemical composition of DH36
The chemical composition of DH36 steel mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni), copper (Cu), molybdenum (Mo) and other elements, and its content must meet the requirements of relevant standards. The content and proportion of these elements determine the mechanical properties and corrosion resistance of the steel.
Mechanical properties of DH36
The mechanical properties of DH36 steel mainly include yield strength (σs), tensile strength (σb), elongation (δ) and impact toughness (Akv). These indicators are important parameters to measure steel quality and must be considered in ship design and construction.
DH36 Application fields
DH36 steel is mainly used in the manufacture of ocean, coastal and inland shipping ship hull structures, such as hull plates, decks, bulkheads, skeletons, etc. These components need to withstand various external forces and pressures during the voyage of the ship, so the steel is required to have high strength and toughness.
