Anchor chains and lines are essential components of a vessel's anchoring system, providing the necessary weight and strength to secure the ship. Anchor chains are typically made of heavy-duty steel links, designed to withstand harsh marine conditions and ensure stability. Both chains and lines work together to connect the anchor to the ship, enabling safe mooring in various water depths.

Grade: Grade 2, Grade 3, U1, U2, U3, R3, R4, R5 (common grades)

Viscosity: Not applicable (chains do not have viscosity properties)

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

Material: High-tensile carbon steel, alloy steel, or stainless steel

Breaking Load: Varies by size and grade (e.g., 12.5 mm Grade 2: ~4.5 tons, 76 mm R4: ~3,500 tons)

Proof Load: Typically 50-70% of breaking load
