Size: 12.5 mm to 152 mm (0.5 inches to 6 inches) diameter
Grade: Grade 2, Grade 3, U2, U3, R3, R4, R5, R6 (common grades per ISO 1704 or ABS standards)
Viscosity: Not applicable (anchor chains are solid metal, no viscosity measurement)
Buoyancy: Negative (sinks in water due to high-density steel material)
Material: High-strength carbon steel or alloy steel (common: ASTM A1021, A1022, or equivalent)
Breaking Load: Varies by size/grade (e.g., R3: 490-687 MPa, R4: 690-880 MPa, R5: 860-1080 MPa)
Proof Load: Typically 50-70% of breaking load (depends on certification standards)
Surface Treatment: Hot-dip galvanized or painted for corrosion resistance
Link Type: Studlink (common for marine anchors) or Studless (for specific applications)
Length: Standard shots of 27.5 meters (90 feet) per chain length
Weight: Varies by size (e.g., 13 mm chain ≈ 2.2 kg/m, 76 mm chain ≈ 122 kg/m)
Certification: Class-approved (ABS, DNV, LR, etc.) for marine use
