High-strength shipbuilding steel plate engineered for hull structures, tanks and other structural components where elevated yield and tensile strength, good toughness and reliable weldability are required. KR DH32 is a marine-grade plate produced to meet the Korean Register (KR) classification requirements and is commonly supplied with classification certificates from major societies (ABS, LR, DNV, GL, BV, NK, CCS, RINA and others) on request.
Key specifications
- Product type: Hot-rolled / control-rolled / TMCP / normalized shipbuilding steel plate
- Grade: KR DH32 (Korean Register shipbuilding grade)
- Thickness range: 3 mm – 280 mm
- Width range: 1,200 mm – 4,200 mm
- Length range: 3,000 mm – 18,000 mm
- Heat treatment: As-rolled, control-rolled, TMCP, or normalized (normalized recommended for improved properties)
- Quality assurances: Classification society certification and mill test certificates available
Performance and fabrication
- Mechanical properties: Higher yield and tensile strength compared with standard structural steels while retaining good low-temperature toughness (specific mechanical values depend on mill certification and chosen heat treatment)
- Corrosion resistance: Suitable for marine environments when combined with appropriate coatings and corrosion protection systems
- Fabrication: Good formability and welding performance with standard shipbuilding welding procedures; specific preheat and post-weld treatments should follow welding procedure specifications and classification society requirements
Typical applications
- Ship hull plating, decks and bulkheads
- Cargo and liquid tanks on vessels
- Offshore structures and marine components requiring enhanced strength
Supply and ordering
Plates can be supplied in standard or customer-specified lengths and widths, with heat-treatment and testing options to meet classification society rules. For commercial enquiries, request a quotation including required thickness, dimensions, heat treatment and certification needs so the supplier can provide lead time, pricing and test documentation.
