The world's largest anchor chains are massive steel links used to secure enormous ships and offshore platforms. These chains can weigh hundreds of tons and stretch thousands of feet in length. They are engineered for extreme strength to withstand harsh marine conditions.

The world's largest anchor chain specifications include:

Size: Diameter up to 168 mm (6.6 inches), length varies per link (typically 5-6 times the diameter).

Grade: Grade R4, R5, or R5S (high-tensile steel), with minimum tensile strength of 800-1,000 MPa.

Viscosity: N/A (chains are solid metal, viscosity not applicable).

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

Material: High-strength alloy steel (typically ASTM A986 or similar).

Weight: Up to 300 kg per meter for largest chains.

Corrosion Resistance: Hot-dip galvanized or coated for marine environments.

Breaking Load: Exceeds 12,000 kN for largest chains.

Common Use: Offshore mooring systems, large vessels (e.g., oil rigs, supertankers).
