Characteristics of DH36 shipbuilding steel

DH36 is a kind of high-strength shipbuilding steel, it has a series of advantages such as high strength, good weldability and corrosion resistance so that it can be used for manufacturing various ship components.

High Strength
Yield strength of DH36 is from 490 MPa to 620 MPa, minimum tensile strength of DH36 is 355 MPa, so it has high strength and suitable for constructing ships that require withstanding large loads and stresses.

Good Welding Performance
The max carbon content in DH36 is 0.18%, so it exhibits good weldability, allowing for welding using conventional methods while maintaining strong joint strength and toughness.

Excellent Cold Forming Properties
DH36 steel can be cold-formed to meet complex shape and contour requirements, making it suitable for manufacturing various ship components and structures.

Corrosion Resistance
Typically, DH36 steel has good resistance to corrosion in seawater, ensuring longevity and durability in harsh marine environments.

Compliance with International Standards
DH36 steel meets the certification and standards of various international classification societies such as ABS (USA) and GL (Germany), ensuring its quality and reliability.

DH36 steel is a superior shipbuilding material widely used in ship construction and marine engineering, capable of meeting complex structural and performance requirements.
