Products FAQ
What is the maximum thickness of your ABS EH32 shipbuilding steel plates?
The ABS EH32 shipbuilding steel plates we supply are typically available in thicknesses ranging from 5 to 150 mm. For extra-thick plates (over 100 mm), we use the TMCP process to ensure product performance.
What is the main difference between ABS Grade EH32 and DH32?
The main difference between the two lies in the minimum impact test temperature.
DH32: The impact test temperature is -20°C.
EH32: The impact test temperature is -40°C, which is a more stringent requirement.
Consequently, EH32 is suitable for lower ambient temperatures or colder marine environments, whilst DH32 is suitable for milder marine environments.
What are the delivery conditions and dimensional ranges for ABS Grade DH36 steel plates?
Common delivery conditions: hot-rolled AR, normalised N, TMCP. TMCP is the most popular choice due to its superior toughness and value for money.
Dimension range: thickness 5–150 mm, width 1200–4200 mm, length 3000–18000 mm. Custom cutting and Z-direction properties Z15/Z25/Z35 are available.
Is ABS DH36 shipbuilding plate easy to weld?
ABS DH36 shipbuilding plate offers excellent weldability; due to its low carbon content, it has a low susceptibility to weld cracking. Conventional welding methods (such as submerged arc welding, gas shielded arc welding and manual arc welding) can generally be used.
However, low-hydrogen welding consumables must be used during welding, and preheating is still required for thicker plates. For thick plates or highly constrained joints, post-weld heat treatment (PWHT) may be necessary to relieve residual stresses.
What are equivalent grades of ABS DH36 steel plate?
International equivalent grades:
China: GB/T 712 DH36
USA: ASTM A131 Grade DH36
Classification society equivalent: CCS DH36, DNV DH36, BV DH36, LR DH36
All equivalent grades meet the same chemical and mechanical requirements.
What standards does ABS DH36 marine steel plate comply with?
ABS DH36 marine steel plate complies with the ABS Materials and Welding Rules, meets the IACS Unified Requirements and conforms to the ASTM A131 standard. It is approved by ABS, CCS, DNV, BV, LR and other major classification societies for use in global shipbuilding and offshore engineering projects.
In which parts of a ship is ABS Grade DH36 steel plate primarily used?
Due to its high strength and resistance to low-temperature impact, it is widely used in:
the main deck and outer plating of the hull, hatch coamings on container ships, structural components of offshore drilling platforms, and critical load-bearing areas of vessels operating in cold waters.
Do you offer cutting services for ABS Grade DH36 marine steel plates?
Yes, we offer value-added services, including plasma cutting and laser cutting.
ABS DH36 VS AH36?
Both have the same yield strength (≥355 MPa). The key difference lies in the impact test temperature: AH36 is tested at 0°C, whilst DH36 is tested at -20°C, offering better safety performance in cold environments.
What are the weldability characteristics of high-strength low-alloy steel plates?
High-strength low-alloy steel plates offer excellent weldability. As their carbon content is typically low (below 0.2%), they present a lower risk of cracking during welding compared to standard high-strength steel plates and generally do not require complex preheating treatments.
