Product Description
U2 U3 Grade Marine Anchor Chains for Ships - Stud Link Design
High-performance steel forging marine mooring & anchor chain with black coating, available in both stud and studless link types. Professionally engineered for marine anchoring and mooring systems of various vessels and offshore facilities, featuring excellent structural strength, seawater corrosion resistance and load-bearing capacity.
Product Overview
Material Advantages
Adopts high-quality marine special alloy steel round bar, main grades include CM490 (U2 grade). The steel forging process optimizes the internal metal structure, eliminating internal stress and significantly improving the chain's tensile, impact and fatigue resistance.
Stud Link Type
- Internal reinforcing studs provide stable structure resistant to deformation
- Suitable for heavy load anchoring of large ships and offshore engineering
- Nominal diameter range: 12.5mm - 120mm
- Standard link size: inside length 4D, outside width 3.6D (D = nominal diameter)
- Standard section length 27.5m, customizable non-standard lengths available
Studless Link Type (Open Link)
- No internal studs, lighter weight
- Easy to match with large shackles, avoiding stud loosening faults
- Nominal diameter range: 12.5mm - 70mm
- Ideal for medium and small vessels, offshore permanent mooring and auxiliary anchoring
- Proof load and breaking load meet U2/U3 grade international standards
Manufacturing Process
- Raw Material Preparation: Select low-carbon steel wire rod with surface treatment to remove impurities
- Chain Forming and Welding: Specialized equipment forms chain links with flash butt welding and shaping
- Heat Treatment: Overall tempering treatment to eliminate stress and improve strength
- Hot-Dip Galvanizing: Immersion in molten zinc at 440-460℃ for corrosion protection
- Final Inspection: Comprehensive quality checks including zinc layer adhesion and dimensional verification
Technical Drawings
