An anchor chain is a heavy-duty chain used to connect a ship's anchor to its hull, providing strength and durability. It helps absorb shocks and ensures the anchor remains securely in place. Anchor chains are typically made of high-strength steel to withstand harsh marine conditions.

Size: 12.5 mm to 152 mm (diameter)

Grade: Grade 2, Grade 3, Grade 4, Grade 5, Grade 6 (common grades for marine applications)

Viscosity: Not applicable (anchor chains are solid metal components)

Buoyancy: Negative (anchor chains sink due to high-density steel material)

Material: High-tensile carbon steel, alloy steel, or stainless steel (commonly galvanized for corrosion resistance)

Breaking Load: Varies by size and grade (e.g., 12.5 mm Grade 3 chain has ~32 kN breaking load)

Proof Load: Typically 50-60% of breaking load (tested for safety)

Link Types: Stud link (most common), studless link, or detachable link

Surface Treatment: Hot-dip galvanizing, zinc coating, or paint for corrosion protection

Weight: Approximately 2-300 kg/m (varies by size and material)

Standards: Complies with ISO 1704, DIN 766, or other maritime classification society rules (e.g., ABS, LR, DNV)
