ABS Grade EH36 Shipbuilding Steel Plate - Low-Temperature High-Strength ABS-Certified Marine Steel

1. What is ABS Grade EH36 shipbuilding steel plate?

ABS Grade EH36 shipbuilding plate is a high-strength structural steel plate designed specifically for the demanding environments of the shipbuilding and offshore industries. It has a minimum yield strength of 355 MPa, maintains excellent low-temperature impact toughness at -40°C, and offers outstanding resistance to saltwater corrosion.

Whether you are constructing deep-water offshore platforms or large container ships, ABS EH36 marine steel plates ensure the safety and integrity of structures in extreme marine environments.

ABS Grade EH36 steel plate is a high-strength marine steel plate certified by the American Bureau of Shipping (ABS). Its key performance advantages include low-temperature toughness at -40°C and a yield strength of ≥355 MPa. This material is suitable for ship and offshore engineering structures operating in extremely cold environments and under high-load conditions.

1. Shipbuilding (Core Application Areas)

1) Ice-class vessels / Polar vessels

Used for the hulls, side structures, decks and ice-bearing zones of icebreakers and Arctic research vessels, offering excellent resistance to extreme cold and ice impact.

2) Large Ocean-going Vessels

Suitable for high-strength decks, bulkheads, deckhouses and longitudinal/transverse members on container ships, bulk carriers and oil tankers, capable of withstanding high bending moments and wave impacts.

3) Specialised Vessels

LNG carriers, chemical tankers: support structures for liquid cargo tanks.

Luxury cruise ships: critical load-bearing compartments.

Workboats: Crane bases and boom structures.

2. Offshore Engineering Structures

1) Offshore Oil and Gas Platforms

Used for jacket structures, legs, platform decks and support columns on jack-up and semi-submersible platforms, offering resistance to storms and seawater corrosion.

2) Offshore Wind Power

Suitable for tower base flanges, foundation jackets and substation platform structures, designed to withstand salt spray and low-temperature environments.

3) Subsea and Port Facilities

Includes subsea pipeline supports, riser structures, main girders for large port cranes, and high-pile caissons for quays.

3. Other Industrial Sectors

1) Cryogenic Pressure Vessels

Used for the cylinders and heads of LNG storage tanks and cryogenic liquid storage tanks, with an operating temperature of -40°C.

2) Heavy-duty Steel Structures

Suitable for main girders of large bridges, beams and columns in industrial buildings in extremely cold regions, and high-strength components of mining machinery.

Key Advantages of ABS Grade EH36 Shipbuilding Steel Plates

1. High Mechanical Strength

ABS EH36 shipbuilding steel plates have a yield strength of not less than 355 MPa and a tensile strength of 490–630 MPa. With their superior load-bearing capacity, they can effectively reduce steel consumption and optimise the structural weight of large vessel hulls.

2. Excellent Low-Temperature Toughness at -40°C

At -40°C, the minimum Charpy V-notch impact energy absorption is no less than 34 J, effectively preventing brittle fracture in extremely cold seawater environments. It is suitable for polar navigation and engineering projects in cold-water regions.

3. Good weldability and formability

Designed with a low-carbon chemical composition (carbon equivalent ≤ 0.40%), ABS EH36 shipbuilding steel plates are suitable for common marine welding processes such as submerged arc welding and manual arc welding. They exhibit low susceptibility to cold cracking and are easy to cut, bend and roll, meeting the manufacturing requirements of complex marine structures.

4. Strong resistance to seawater corrosion

Through the judicious addition of alloying elements such as Cu, Ni and Cr, the material’s resistance to salt spray, seawater and marine atmospheric corrosion is enhanced, extending its service life in harsh marine environments.

5. High structural stability and fatigue resistance

Fine-grain rolling and TMCP heat treatment technologies are employed to ensure a uniform internal microstructure, providing excellent fatigue resistance and the ability to withstand deformation under dynamic marine loads.
