The American Bureau of Shipping (ABS) is an internationally recognised and authoritative marine classification society. All ABS Grade EH32 shipbuilding steel plates must undergo factory certification and batch inspection. Only steel manufacturers holding ABS production certification are permitted to produce certified EH32 products. This certification serves as a key entry credential for the global marine engineering market. The core of quality inspection for ABS EH32 marine steel plates involves five key areas in accordance with ABS specifications: chemical composition, mechanical properties, non-destructive testing, dimensions and appearance, and document review. The focus lies on low-temperature impact toughness at -40°C and the pass rate for internal flaw detection.
As ABS Grade EH32 shipbuilding steel plates are used in the construction of vessels and offshore structures operating in cold-water environments, the welding and fabrication processes involved are subject to extremely stringent requirements. If the processes are not carried out correctly, the material is highly susceptible to brittle fracture at low temperatures, which can seriously compromise the safety of the hull or offshore structure and may even lead to accidents.
Thanks to its high strength, low-temperature toughness at -40°C and excellent weldability, ABS Grade DH32 shipbuilding steel plate has become a key structural material for ocean-going vessels and offshore engineering, being used in core structures such as decks, bulkheads, hulls and platform columns.
Projects such as ocean-going vessels, offshore wind farms and deep-sea drilling platforms often require non-standard structures, and standardised, off-the-shelf plates are often unsuitable for these specific construction conditions. We offer comprehensive customised processing of ABS Grade DH36 shipbuilding steel plates, covering services such as non-standard dimensions, surface corrosion protection, heat treatment and prefabrication, providing a one-stop solution to meet the technical requirements of high-end offshore engineering projects. Below, we outline our detailed customisation solutions.
ABS Grade DH36 shipbuilding steel plate has a carbon equivalent of ≤0.40% and offers excellent weldability. However, due to its high strength, thick plates are prone to cold cracking and a reduction in toughness in the heat-affected zone (HAZ) during welding. Strict adherence to ABS welding codes, the use of certified welding consumables, and appropriate control of heat input are key to ensuring weld strength and meeting ship safety standards.
