Large anchor chains are heavy-duty chains used to secure ships and vessels to the seabed. They are typically made of high-strength steel to withstand immense forces and harsh marine conditions. Their robust design ensures stability and safety for anchored ships.

Size: Typically ranges from 12.5 mm to 152 mm in diameter.

Grade: Common grades include Grade 2, Grade 3, and U3, with higher grades offering greater strength.

Viscosity: Not applicable, as anchor chains are solid metal components.

Buoyancy: Negligible, as anchor chains are made of dense steel and sink in water.

Material: Usually constructed from high-tensile steel, often galvanized for corrosion resistance.

Breaking Load: Varies by size and grade, ranging from 4.75 tons to over 3,500 tons.

Proof Load: Typically 50% to 70% of the breaking load, depending on grade.

Finish: Hot-dip galvanized or bare steel, with some chains coated for additional protection.

Link Types: Common types include stud link (for strength) and studless link (for flexibility).

Weight: Approximately 2.2 kg/m to 300 kg/m, depending on size and material.

Corrosion Resistance: Enhanced by galvanization or special coatings in marine environments.

Standards: Complies with international standards like ISO 1704, ABS, DNV, and Lloyd's Register.
