Marine mooring chains are heavy-duty chains used to secure ships and floating structures to docks or the seabed. Anchor chains connect the vessel's anchor to its hull, providing strength and weight to ensure stability. Both are typically made from high-grade steel for durability and corrosion resistance in harsh marine environments.

Marine Mooring Chain and Anchor Chain Specifications:

Size: Ranges from 10mm to 210mm in diameter, depending on application.

Grade: Common grades include Grade 2, Grade 3, R3, R4, R5, and R6, with higher grades offering greater strength.

Viscosity: Not applicable (chains are solid metal).

Buoyancy: Negative buoyancy (sinks in water due to high-density steel).

Material: Typically made from high-tensile carbon steel or alloy steel, often galvanized for corrosion resistance.

Breaking Load: Varies by grade and size (e.g., R4 grade 100mm chain has ~4,500 kN breaking load).

Proof Load: Typically 50-70% of breaking load for testing.

Finish: Hot-dip galvanized, self-colored (black), or painted.

Standards: Complies with ISO 1704, ABS, DNV, or other classification society rules.

Link Types: Studlink (common for mooring) or Studless (for some anchor chains).
