Heavy anchor chains are robust, large-diameter chains used to secure ships and offshore structures. They provide strong holding power and durability in harsh marine environments. Anchor chains are typically made of high-strength steel to withstand extreme loads and corrosion.

Heavy Anchor Chain Specifications:

Size: 20mm to 200mm diameter (common sizes: 20mm, 25mm, 30mm, 35mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 120mm, 150mm, 200mm)

Grade: Grade 2, Grade 3, Grade 4, U2, U3, R3, R4, R5 (based on strength and certification standards)

Viscosity: Not applicable (chains are solid metal, viscosity is a fluid property)

Buoyancy: Negative (steel chains sink in water due to high density)

Material: High-tensile carbon steel, alloy steel, or stainless steel (common: ASTM A1023, DIN 766, ISO 1704)

Breaking Load: Varies by size and grade (e.g., 20mm Grade 3 chain ~150 kN, 100mm Grade R4 ~10,000 kN)

Weight: Approximately 10-300 kg/m (depends on diameter and material)

Surface Treatment: Hot-dip galvanized, painted, or bare metal (for corrosion resistance)

Certifications: ABS, DNV, LR, GL, BV, CCS (depending on marine classification standards)

Link Type: Studlink (common for heavy chains) or Studless (for specific applications)
