Anchor chains for boats are heavy-duty metal links used to connect the anchor to the vessel, ensuring secure holding. They provide weight to help the anchor dig into the seabed and absorb shocks from waves or wind. Made from galvanized or stainless steel, they resist corrosion and withstand harsh marine conditions.

Size: 1/4 inch to 2 inches in diameter

Grade: Grade 30, Grade 40, Grade 70 (common grades for marine use)

Viscosity: Not applicable (chains do not have viscosity properties)

Buoyancy: Negative (sinks in water due to high-density material)

Material: High-tensile carbon steel, galvanized steel, or stainless steel

Finish: Hot-dip galvanized or self-colored (stainless steel)

Working Load Limit (WLL): Varies by size and grade (e.g., 1/2" Grade 30 chain ~4,500 lbs)

Break Strength: Typically 4x WLL (e.g., 1/2" Grade 30 ~18,000 lbs)

Link Type: Stud link (common for anchor chains) or open link

Corrosion Resistance: High (galvanized or stainless steel options)

Weight: Approximately 1.5 to 10 lbs per foot (varies by size and material)
