Used mooring chains and anchor chains are pre-owned heavy-duty chains designed for securing vessels and offshore structures. These chains are typically made from high-strength steel and show signs of wear from previous use. They remain reliable for marine applications after thorough inspection and maintenance.

Size: 1.5 inches to 5 inches (38 mm to 127 mm) nominal diameter

Grade: Grade 2, Grade 3, or R3, R4, R5 (common grades for used chains)

Material: High-tensile carbon steel or alloy steel

Viscosity: Not applicable (solid metal chains)

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

Breaking Load: Varies by size and grade (e.g., 1.5-inch Grade 3 ~ 225 metric tons)

Proof Load: Typically 50-60% of breaking load

Corrosion Resistance: Limited (used chains may have wear or rust)

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

Link Type: Studlink or studless (common in mooring/anchor chains)

Length: Typically supplied in 15-fathom (27.5m) shots or custom lengths

Weight: 20 kg/m to 200 kg/m (varies by size and material)

Certification: May come with prior survey reports (if available)
