Mooring anchor chains are heavy-duty chains used to secure vessels to the seabed, providing stability and safety. They are designed to withstand harsh marine conditions, including corrosion and high tension. Anchor chains are a critical component in maritime operations, ensuring ships remain stationary in water.

Viscosity: Not applicable (solid metal construction)

Buoyancy: Negative (sinks in water due to high density)

Breaking Load: Varies by size and grade (e.g., 13mm Grade 3: ~47 tons, 210mm R5: ~12,500 tons)

Proof Load: Typically 50-70% of breaking load

Surface Treatment: Hot-dip galvanized or painted for corrosion resistance

Chain Type: Studlink or studless (common for mooring)
