Size: 12.5 mm to 152 mm (diameter)
Grade: Grade 2, Grade 3, U1, U2, U3, R3, R4, R5 (common grades for marine chains)
Viscosity: Not applicable (chains are solid metal components)
Buoyancy: Negative (anchor chains are designed to sink)
Material: High-tensile carbon steel, alloy steel, or stainless steel (galvanized for corrosion resistance)
Breaking Load: Varies by size and grade (e.g., 12.5 mm Grade 2 chain ≈ 38 kN, 76 mm R4 chain ≈ 11,000 kN)
Proof Load: Typically 50% of breaking load
Certification: ABS, DNV, LR, BV, or other classification society standards
Finish: Hot-dip galvanized or self-colored (bare metal)
Link Type: Studlink or studless (common for anchor chains)
Length: Standard shots of 27.5 meters (90 ft) per shackle
Weight: Varies by size (e.g., 12.5 mm chain ≈ 3.5 kg/m, 76 mm chain ≈ 123 kg/m)
Corrosion Resistance: Enhanced by galvanization or special coatings
Welding: Flash butt welding or electric resistance welding for link integrity
