The best anchor chain for saltwater is typically made of high-grade galvanized steel or stainless steel to resist corrosion. A G4 or BBB chain with a hot-dipped galvanized coating offers superior strength and durability. Ensure proper sizing and quality certifications for reliable performance in harsh marine environments.

Size: 1/4" to 2" diameter (common sizes for marine use)

Grade: Grade 30 (mild steel), Grade 40 (high-test), Grade 70 (extra high-test), or BBB (BBB chain)

Material: Hot-dip galvanized steel or stainless steel (316L for superior saltwater resistance)

Viscosity: N/A (not applicable for anchor chains)

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

Working Load Limit (WLL): Varies by size and grade (e.g., 1/2" Grade 40 chain has ~4,700 lbs WLL)

Break Strength: Typically 4x the WLL (e.g., 1/2" Grade 40 chain has ~18,800 lbs break strength)

Link Type: Stud link (most common for anchor chains, prevents twisting)

Corrosion Resistance: High (galvanized or stainless steel for saltwater use)

Finish: Hot-dip galvanized or polished stainless steel

Standards: Meets ABS, DNV, or ISO standards for marine applications
