Anchor chains are heavy-duty chains used to secure anchors to ships, providing stability and holding power. They are typically made of high-strength steel to withstand harsh marine conditions. The length and thickness of anchor chains vary based on the size and type of vessel.

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: Negative buoyancy due to high-density steel material; sinks in water.

Material: Usually made of high-tensile steel, such as ASTM A1023 or equivalent.

Breaking Load: Varies by size and grade, e.g., 12.5 mm chain may have ~47 kN, while 152 mm may exceed 15,000 kN.

Surface Treatment: Often galvanized or coated for corrosion resistance.

Length: Standard shots are 27.5 meters (15 fathoms), but custom lengths are available.

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

Certification: Complies with international standards like ISO 1704, ABS, DNV, or LR.
