An anchor with a chain, known as an anchor chain, is a heavy-duty metal chain used to secure a vessel to the seabed. The chain provides weight and durability, helping to stabilize the anchor and absorb shocks from waves or currents. It is a critical component in maritime operations for ensuring safe and reliable mooring.

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 materials like steel and sink in water.

Material: Usually high-tensile steel, galvanized steel, or stainless steel for corrosion resistance.

Length: Standard lengths vary, often supplied in 27.5-meter shots (shackled together).

Breaking Load: Varies by grade and size, e.g., Grade 3 chains have higher breaking loads than Grade 2.

Weight: Depends on size and material, typically measured in kg/m (e.g., 12.5 mm chain ≈ 3.5 kg/m).

Finish: Hot-dip galvanized or painted for enhanced durability in marine environments.

Certification: Often complies with international standards like ISO 1704 or ABS/DNV/GL classifications.
