The Old Anchor Chain refers to a vintage or historical chain used to secure anchors on ships. Anchor chains are heavy-duty metal links designed to withstand marine conditions and provide stability. They play a crucial role in mooring vessels safely.

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 constructed from high-tensile steel, galvanized steel, or alloy steel for corrosion resistance and durability.
