Product Description of Shipbuilding Steel Plate

Shipbuilding steel plates are hot-rolled steel plates manufactured in accordance with classification society rules, specially used for hull structures and marine engineering. They feature high strength, superior toughness, excellent seawater corrosion resistance and good weldability, suitable for harsh working conditions of ocean-going, coastal and inland waterway vessels as well as offshore platforms.

1. Applicable Standards & Certifications

1.1 Domestic Standards

GB 712-2011: Structural steel for ships and marine engineering (core national standard of China).
CCS (China Classification Society):Ordinary strength grades: CCSA, CCSB, CCSD, CCSEHigh strength grades: AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, FH36, FH40

1.2 International Classification Society Certifications

ABS, BV, DNV, LR, KR, RINA. Products support single certification or multi-certification to meet requirements of ship owners worldwide.

2. Material Grades & Chemical Composition

2.1 Ordinary Strength Shipbuilding Plates (Yield Strength ≥ 235MPa)

Grade	C (%)	Mn (%)	Si (%)	S (%)	P (%)
CCSA	≤0.21	≥2.5×C	0.10-0.50	≤0.035	≤0.035
CCSB	≤0.21	0.80-1.20	0.10-0.50	≤0.035	≤0.035
CCSD	≤0.18	0.60-1.20	0.10-0.50	≤0.030	≤0.030
CCSE	≤0.18	0.70-1.35	0.10-0.50	≤0.025	≤0.025

2.2 High Strength Shipbuilding Plates (Yield Strength: 315-390MPa)

Take AH36, DH36, EH36 as examples: C ≤ 0.18%, Mn 0.90-1.60%, Si 0.10-0.50%, S ≤ 0.025%, P ≤ 0.025%.Carbon equivalent (Ceq) ≤ 0.36% (for thickness ≤ 50mm) to guarantee excellent weldability.

3. Specification Parameters

Thickness: 2.5-150mm (Common range: 6-50mm)
Width: 1220-4200mm (Standard sizes: 1500/1800/2000/2200/2500mm)
Length: 5000-18000mm (Custom fixed length / multiple length available)
Delivery Condition: As Rolled (AR), Normalized (N), Thermo-Mechanical Control Process (TMCP, widely used for high strength plates), Quenched & Tempered (QT, for high-end application)
Theoretical Weight Calculation (kg): Length(m) × Width(m) × Thickness(mm) × 7.85

4. Main Mechanical Properties

4.1 Ordinary Strength Grades (CCSA/CCSB/CCSD/CCSE)

Yield Strength: ≥ 235MPa
Tensile Strength: 400-520MPa
Elongation: ≥ 22%
Impact Test: CCSA & CCSB (Room temperature); CCSD (-20℃); CCSE (-40℃), Impact energy ≥ 27J

4.2 High Strength Grades (AH36/DH36/EH36)

Yield Strength: ≥ 355MPa
Tensile Strength: 490-630MPa
Elongation: ≥ 20%
Impact Test: AH36 (Room temperature); DH36 (-20℃); EH36 (-40℃), Impact energy ≥ 34J

5. Key Characteristics

High Toughness: Resist low-temperature brittle fracture and withstand wave impact and alternating loads.
Good Corrosion Resistance: Resist chemical and electrochemical corrosion caused by seawater, slow down rusting and marine organism adhesion.
Excellent Weldability: Low carbon equivalent, suitable for complex hull welding and effectively reduce cracking risk.
High Fatigue Resistance: Resist deformation and cracking under long-term vibration and variable loads.
Good Processability: Easy for cutting, bending and stamping to meet complex forming requirements of hull structures.

6. Main Applications

6.1 Shipbuilding Industry

Hull structures: Hull shell, bottom plate, deck, bulkhead, side shell plate
Key components: Cargo hold, oil tank, water tank, engine room frame, superstructure
Applicable vessel types: Bulk carrier, oil tanker, container ship, ro-ro ship, fishing vessel, icebreaker, LNG carrier

6.2 Marine Engineering

Offshore platforms: Jacket, leg, trestle, lifting mechanism
Port facilities: Wharf, fender, mooring equipment, caisson
Special equipment: Offshore engineering vessel, wind power foundation, support for subsea pipeline

6.3 Other Industrial Fields

Heavy-duty machinery, cranes, pressure vessels, bridges and storage tanks.

7. Production & Inspection

7.1 Production Process

Ironmaking → Steelmaking → Continuous Casting → Hot Rolling → Finishing → Nondestructive Testing → Marking → Packaging

7.2 Quality Inspection

Mechanical test: Tensile test, impact test, bend test, hardness test
Nondestructive test: Ultrasonic Testing (UT, mandatory), Magnetic Particle Testing (MT), Radiographic Testing (RT)
Surface inspection: Free from cracks, scabs, folds and excessive rust; dimensional tolerance complies with relevant standards.

7.3 Marking & Packaging

Products are bundled and wrapped with anti-rust film. Marks including standard, grade, dimension, batch number and classification society certification are clearly printed. Official quality certificates are provided together with goods.

8. Delivery & Service

Origin: Major steel mills located in Tianjin, Shandong, Jiangsu and other regions.
Lead Time: 5-7 working days for standard stock items; 7-15 days for customized products.
Shipment: Delivered from Tianjin Port & Qingdao Port via truck or sea transportation. Goods are well protected against moisture and collision.
Additional Service: Provide full set of CCS, ABS, BV and other certification documents. Custom processing including cutting, sandblasting and painting is available.
