Used ship anchor chains are pre-owned marine-grade chains designed to secure vessels by connecting the anchor to the ship. These chains are typically made of high-strength steel and undergo rigorous testing for durability and corrosion resistance. They are commonly available in various sizes and grades to suit different maritime applications.

Size: 12.5mm to 152mm (diameter)

Grade: Grade 2, Grade 3, or U3 (common for used chains)

Viscosity: Not applicable (anchor chains are solid metal)

Buoyancy: Negative (sinks due to high-density steel material)

Material: High-tensile carbon steel or alloy steel

Finish: Hot-dip galvanized or bare (depending on condition)

Length: Typically supplied in 27.5-meter shots (used chains may vary)

Proof Load: Varies by grade (e.g., Grade 3: 700-900 N/mm²)

Break Load: 20-4000 tons (depending on size and grade)

Certification: May have expired or partial certification (if used)

Corrosion Resistance: Dependent on remaining galvanization or coating

Common Standards: ABS, DNV, LR, or ISO 1704 (for original manufacture)
