Products FAQ
What are the delivery conditions for BV EH32 marine steel plates?
Delivery conditions are classified by plate thickness range as follows:
| Thickness Range | Delivery Condition | Description |
|---|---|---|
| ≤ 50 mm | Thermomechanically Controlled Process (TMCP) or Normalized (N) | Typically supplied in the TMCP condition, which offers lower cost and good weldability. |
| > 50 mm – 100 mm | Normalized (N) | Normalizing refines the grain structure and ensures that the core of the steel plate meets the specified low-temperature impact toughness requirements. |
| > 100 mm | Quenched + Tempered (Q+T) | For extra-thick steel plates, the Q+T heat treatment process is used to ensure mechanical properties throughout the entire cross-section. |
Can your BV DH36 marine steel plates undergo ultrasonic testing?
Yes. Ultrasonic testing (UT) at various levels can be performed according to customer requirements to detect internal inclusions and defects in the steel plates.
Do your BV DH36 ship plates support third-party inspection?
Yes. All of our BV DH36 steel plates support third-party inspections by internationally recognized authorities such as SGS, BV, DNV, and ABS. The products come with complete official BV certification and original Mill Test Certificates (MTCs), enabling full-process quality traceability for heavy-duty offshore engineering projects in cold regions worldwide.
Can you supply BV-certified BV DH36 shipbuilding steel plates in custom sizes?
Yes. We offer full-range custom manufacturing and one-stop value-added processing services for BV DH36 shipbuilding steel plates. All custom products come with an official BV-certified Mill Test Certificate (MTC), meeting the requirements for custom sizing, precision machining, and compliance verification for heavy-duty offshore engineering projects in cold waters worldwide.
What is the main difference between BV DH36 and BV EH36 marine steels?
The key differences between the two lie in their low-temperature impact toughness grades and application scenarios:
BV DH36: Requires impact toughness at -20°C and is suitable for conventional cold-water regions and seasonal low-temperature operating conditions;
BV EH36: Requires impact toughness at -40°C and is suitable for polar and extreme sub-zero marine environments.
Selection Recommendations:
1) For projects in conventional cold waters, BV DH36 offers better value for money and avoids the performance redundancy and additional costs associated with BV EH36.
2) Projects in polar and extremely low-temperature marine environments must use BV EH36 to prevent structural brittle fracture under harsh, extremely low-temperature marine conditions.
Does your BV DH36 marine steel plate come with official BV certification?
Yes. All of our BV DH36 steel plates are sourced from leading Chinese steel mills recognized by BV. They hold valid official certification from Bureau Veritas (BV) and are accompanied by an EN 10204 3.2 Mill Test Certificate (MTC).
Each batch of steel plates is traceable by production furnace number, enabling full-lifecycle quality traceability management. The certificates are valid worldwide and fully meet requirements for ship registration, offshore engineering acceptance, third-party inspection and certification, and cross-border customs clearance.
Does your BV Grade DH32 shipbuilding steel plate support third-party inspection?
Yes. All of our BV Grade DH32 steel plates are subject to inspection by internationally recognized third-party organizations such as SGS.
The products come with complete official BV certification and original mill test certificates (MTC), ensuring full traceability of quality throughout the entire process.
Is BV DH32 shipbuilding steel suitable for ocean-going vessels?
Yes, it is. BV DH32 offers stable structural strength and low-temperature impact toughness at -20°C, as well as excellent resistance to fatigue brittle fracture and corrosion in cold marine environments, making it particularly suitable for ocean-going vessels operating in temperate and subarctic waters.
What are the main differences between BV DH32 and BV DH36 marine steels?
Both have the same low-temperature impact toughness; the key differences lie in their strength grades and load-bearing capacities:
BV DH32: Minimum yield strength of 315 MPa; suitable for ships operating in cold waters and offshore engineering projects under moderate loads, offering good value for money;
BV DH36: Minimum yield strength of 355 MPa; offers higher strength and is suitable for heavy-load vessels and offshore engineering projects in cold waters.
Selection Recommendation: For applications with moderate load requirements, BV DH32 is more cost-effective; for high-load or extreme operating conditions, BV DH36 should be selected.
What is the range of available dimensions for BV DH32 shipbuilding steel plates?
Available dimensions depend on the steel mill’s production capacity. The typical range of specifications is as follows:
Thickness: 5 - 150 mm
Width: 1,500 - 4,000 mm
Length: 6,000 - 18,000 mm
In addition, special dimensions can be customized according to the shipyard’s requirements and the approval criteria of classification societies.
