International Shipbuilding Standards of Hot Rolled DH36 Alloy Steel Plates
Global Shipbuilding Standards
Shipbuilding steel plates are manufactured in compliance with the rigorous standards set by classification societies across various countries. These organizations certify the production methods and quality of marine-grade steels, ensuring their suitability for offshore and shipbuilding applications. Recognized classification societies include:
ABS (American Bureau of Shipping)
BV (Bureau Veritas)
CCS (China Classification Society)
DNV (Det Norske Veritas)
GL (Germanischer Lloyd)
HR (Hellenic Register of Shipping)
KR (Korean Register of Shipping)
LR (Lloyd’s Register of Shipping)
NK (Nippon Kaiji Kyokai)
RINA (Registro Italiano Navale)
IRS (Indian Register of Shipping)
Shipbuilding steel plates are also categorized based on yield strength and impact resistance at different temperatures:
Grade A – Designed for use at room temperature (20°C)
Grade B – Tested for impact resistance at 0°C
Grade D – Suitable for cold environments down to -20°C
Grade E – Withstands extreme low temperatures of -40°C
Applications of Hot Rolled DH36 Alloy Steel Plates
Hot Rolled DH36 alloy steel plates are widely used in the marine industry due to their high strength, excellent toughness, and resistance to harsh environmental conditions. Common applications include:
Ship Hull Construction
Provides structural strength and resilience for hull sections exposed to constant stress and corrosive seawater.
Deck Structures
Ensures structural stability and safety on ship decks for both personnel and cargo.
Internal Ship Components
Ideal for building bulkheads, beams, frames, and other integral load-bearing parts.
Machinery and Equipment Mounting
Offers a reliable base for installing heavy machinery, engines, and shipboard systems.
Offshore Marine Structures
Used in the construction of platforms, oil rigs, and marine terminals due to its robustness.
Ship Repair and Maintenance
Frequently applied in replacing damaged or corroded steel sections during maintenance operations.
