Multi-Certification

ABS steel plate may be certified to multiple specifications when the material meets each standard’s requirements. ABS certification is issued by the American Bureau of Shipping for marine and shipbuilding applications, while API 2H is issued by the American Petroleum Institute for offshore structural steel plate. When required, certain marine/offshore plate may be multi-certified on the mill test report to meet ABS, API 2H and other applicable project specifications. 

Product MTRs commonly also certify the plate for
ABS API 2H Grade 42

API 2H Grade 50

If projects require multi-certified plate material, the mill test report (MTR) will include results for material supplementary requirements, or "supplements." Leeco's material almost always includes supplements S1, S3, S4 and S5. Contact a member of our team to learn more.

Frequently Asked Questions

Learn more about ABS steel plate.
The best materials for offshore equipment are those that can withstand saltwater exposure, cyclic loading, harsh weather and demanding structural requirements. Offshore fabricators commonly use API 2H Grade 50, ABS EH36, ABS DH36 and other marine-grade steel plates engineered for welded offshore structures. These materials offer high strength, excellent weldability, strong impact resistance and improved fatigue performance. Applications such as offshore platforms, tubular joints, suction piles, cranes, winches, anchoring systems, manifolds and subsea structures require materials capable of resisting plastic fatigue loading and maintaining integrity under dynamic conditions. API 2H is widely specified because it was specifically developed for critical offshore structures where toughness and reliability are essential.
ABS-certified steel plate is marine-grade steel plate approved by the American Bureau of Shipping for shipbuilding and marine applications. It is standardized and highly regulated to meet specifications for use in maritime applications, including structural parts of ships, barges and marine equipment. ABS plate is available in ordinary-strength and higher-strength grades designed to perform in harsh maritime conditions where strength, toughness and certification requirements matter.
ABS certification means the steel plate meets American Bureau of Shipping requirements for marine or shipbuilding use. For shipbuilders and fabricators, ABS certification confirms that the material meets required standards for vessel or marine equipment construction, including grade, strength, toughness, testing and traceability requirements documented on the Mill Test Report.
Ordinary-strength ABS steel plate includes grades such as A, B, D and E, while higher-strength ABS steel plate includes grades such as AH36, DH36, EH36 and FH36. The main difference is strength and toughness performance. Ordinary-strength ABS grades generally have lower yield strength, while the higher-strength 36 grades are commonly listed with a 51 ksi minimum yield strength. Higher-strength ABS plate is typically used when shipbuilding or marine structures require stronger performance, added toughness or more demanding service conditions.
AH36, DH36, EH36 and FH36 are higher-strength ABS shipbuilding steel plate grades. The key difference is Charpy impact toughness performance at different test temperatures. AH36 is commonly tested at 32°F (0°C), DH36 at -4°F (-20°C), and EH36 at -40°F (-40°C). FH36 is typically associated with more severe low-temperature service, often around -76°F (-60°C), but exact requirements should be confirmed against ABS rules, the project specification and the MTR.
ABS steel plate is used in the marine industry to build structural parts of ships, barges and marine equipment. Higher-strength ABS grades may be used in ship hulls, decks, bulkheads, offshore structures and other marine components that must withstand demanding service conditions, including wave forces, wind, saltwater exposure and low-temperature environments.
ABS steel plate may be certified to multiple specifications on mill test reports when the material satisfies each standard’s requirements. ABS certification applies to shipbuilding and marine applications, while API 2H is tied to offshore structural steel plate used in welded offshore structures. Dual certification to ABS and API 2H may be requested when a marine or offshore fabrication project needs material that meets both classification and offshore structural requirements. Required certifications should be confirmed when the plate is ordered.
ABS steel plate refers to shipbuilding steel plate certified by the American Bureau of Shipping for marine applications, while ASTM A131 is the material specification for structural steel used in ship construction. ABS-certified shipbuilding grades align with ASTM A131 grades, including ordinary-strength grades such as A, B, D and E and higher-strength grades such as AH36, DH36, EH36 and FH36. The key difference is that ASTM A131 defines the shipbuilding steel requirements, while ABS certification confirms the material is approved for use in applicable shipbuilding or marine projects.
