Ship anchor chains are heavy-duty metal links that connect the anchor to the vessel, ensuring secure mooring. They provide strength and flexibility to withstand ocean currents and winds. The chain's weight helps keep the anchor flat on the seabed for better holding power.

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

Grade: Common grades include Grade 2, Grade 3, and High-Test (Grade 30), with varying tensile strengths.

Viscosity: Not applicable to anchor chains; viscosity is a fluid property.

Buoyancy: Anchor chains are negatively buoyant, designed to sink and provide holding power.

Material: Usually made of high-strength carbon steel or alloy steel, often galvanized for corrosion resistance.

Chain Type: Studlink or studless chains, with studlink providing higher strength and stability.

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

Proof Load: Typically 50-70% of the breaking load, used for testing chain integrity.

Corrosion Resistance: Enhanced by galvanization or other coatings.

Length: Standard lengths include 27.5 meters (shot) or custom lengths as required.

Weight: Depends on size and material, e.g., 12.5 mm chain weighs ~2.2 kg/m, while 152 mm can exceed 300 kg/m.
