Thick anchor chains are heavy-duty marine components designed to secure vessels by connecting the anchor to the ship. They are built to withstand extreme forces, corrosion, and wear in harsh maritime environments. Their robust construction ensures reliable holding power and durability for long-term use.

Size: 12mm to 200mm diameter

Grade: Grade 2, Grade 3, U2, U3, R3, R4, R5, R3S, R4S, R5S

Viscosity: N/A (Not applicable for chains)

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., 12mm Grade 3: ~47 kN, 100mm R4: ~12,500 kN)

Proof Load: Typically 50-70% of breaking load

Surface Treatment: Hot-dip galvanized, painted, or bare

Standards: ISO 1704, DIN 766, ABS, LR, DNV, etc.

Link Types: Studlink (common), Studless, or Open link

Weight: Varies by size (e.g., 12mm: ~2.2 kg/m, 100mm: ~150 kg/m)

Corrosion Resistance: Dependent on coating and material

Elongation: Minimal under load (high rigidity)

Temperature Range: -20°C to +200°C (varies by material)
