High Test Anchor Chain Supplier - Anchor Chains

High Test Anchor Chains are heavy-duty chains made from high-tensile steel, offering superior strength and durability. They are commonly used in marine applications for anchoring large vessels due to their resistance to stress and corrosion. These chains are rigorously tested to meet stringent safety and performance standards.

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
