The Windlass Chain is a mechanical device used to hoist and lower anchors on ships. Anchor Chains are heavy-duty chains that connect the anchor to the vessel, providing strength and durability. Both are critical for secure anchoring and maritime operations.

Windlass Chain and Anchor Chain Specifications:

Size: 1/4" to 2" (6mm to 50mm) nominal diameter.

Grade: Common grades include Grade 2, Grade 3, and High-Test (Grade 30, Grade 40).

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

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

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

Breaking Load: Varies by size and grade (e.g., 1/2" Grade 30 chain has ~12,000 lbs breaking load).

Proof Load: Typically 50-60% of breaking load for certification.

Link Type: Studlink or Studless (studlink provides higher strength and stability).

Finish: Hot-dip galvanized, painted, or bare steel.

Standards: Complies with ABS, DNV, ISO, or other maritime classification standards.
