What is D36 steel plate and its properties

D36 steel plate is a high-strength structural steel used in offshore and marine applications. It is typically used for hull structures and provides excellent weldability and toughness. D36 steel plate is also known as ABS grade DH36.

The properties of D36 steel plate include a minimum yield strength of 355 megapascals (MPa), a tensile strength of 490-620 MPa, and an elongation of 21% at 50 degrees Celsius. It has excellent low-temperature toughness and is highly resistant to corrosion in seawater.

D36 steel plate is thermomechanically rolled, which means it is produced using a controlled rolling process that results in a more uniform microstructure and improved mechanical properties. This process also allows for tighter tolerances and better surface quality.

In addition to its use in shipbuilding, D36 steel plate is also used in other industries such as construction and heavy equipment manufacturing. Its high strength and toughness make it an ideal material for applications where strength and durability are critical factors.
