DH36 marine steel plate DH36 shipbuilding hull steel plate/coil

ASTM A131 DH36 steel Description

DH36 marine steel plate, also known as offshore structural steel plate, is a kind of high-strength low-alloy structural steel plate with high strength and good impact toughness, which is very suitable for ship structure manufacturing and is an important raw material for ship structure. It has good rust resistance and corrosion resistance to wet environment, which can meet the strict requirements of marine environment and can also be used in coastal areas such as the Mediterranean. DH36 marine steel plate has good mechanical properties, good toughness and ductility, can resist destructive vibration and impact, and ensure the safety and reliability of the ship structure.

ASTM A131 DH36 shipbuilding steel has excellent processing and exploitation performance at the same time, and can be used to manufacture a variety of high-quality parts, often used to manufacture ship deck, ship equipment, mechanical equipment, port machinery, gears, bearings, etc. Heat treatment process of DH36 marine steel plate: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc. DH36 ship plate adds the requirements for the thickness direction performance of the steel plate, that is, the Z-direction performance, and the additional Z-direction performance is DH36-Z35.

As an important DH36 shipbuilding hull steel plate/coil manufacturer in China, Beibang Iron and Steel can provide various classification society certifications: CCS, ABS, GL, BV, DNV, NK, LR, RINA, KR. It can meet various dimensional requirements of customers, and can provide deep processing services such as cutting, welding, bending, etc.

ASTM A131 DH36 steel Chemical composition

(heat analysis, % max unless otherwise specified)

Notes: 1) The contents of any other element intentionally added is to be determined and reported.

1, If the content of soluble aluminum is not less than 0.015 %, the minimum required silicon content does not apply.
2, Columbium and niobium are considered interchangeable names for the same element and both names are acceptable for use in A01 standards.
3, The indicated amount of aluminum, columbium (niobium), and vanadium applies if any such element is used singly.
4, Ca element need not be reported on the mill sheet unless intentionally added.
