Anchor chain grades, such as Grade 2, Grade 3, and Grade 4, indicate the material strength and durability of the chains. Higher-grade chains offer greater tensile strength and resistance to wear, suitable for larger vessels. Common standards include ISO, ABS, and DIN specifications for marine applications.

Anchor Chain Grades: Grade 1, Grade 2, Grade 3, Grade 4, Grade 5 (G1, G2, G3, G4, G5).

Size Range: 6mm to 210mm (diameter).

Material: High-tensile carbon steel or alloy steel.

Tensile Strength: G1 (300-400 N/mm²), G2 (490-690 N/mm²), G3 (690-880 N/mm²), G4 (880-1,080 N/mm²), G5 (1,080-1,370 N/mm²).

Viscosity: Not applicable (solid steel chains).

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

Corrosion Resistance: Typically galvanized or coated for marine environments.

Weight per Meter: Varies by size (e.g., 13mm chain ≈ 3.5 kg/m, 76mm chain ≈ 123 kg/m).

Certifications: ABS, DNV, LR, BV, etc., depending on marine standards.
