Anchor Chain Marking Standard: ISO 1704, DIN 766, or other applicable standards.
Size: Ranges from 12.5 mm to 152 mm (½ inch to 6 inches) in diameter.
Grade: Common grades include Grade 2, Grade 3, and High-Tensile (Grade 4, U1, U2, U3, R3, R4, R5).
Viscosity: Not typically specified for chains; applies to lubricants used in chain maintenance.
Buoyancy: Negative buoyancy due to steel material; weight in water is approximately 87% of in-air weight.
Material: Typically forged or welded high-strength carbon steel or alloy steel (e.g., ABS, LR, DNV certified).
Finish: Hot-dip galvanized or self-colored (ungalvanized) for corrosion resistance.
Proof Load: Varies by grade and size (e.g., Grade 3 chains have higher proof load than Grade 2).
Break Load: Determined by material and grade (e.g., U3 chains have higher break load than U2).
Length: Standard stud link chain lengths are 27.5 meters (90 feet) per shot.
Stud Link: Standard studded design for strength and stability.
Certification: Class-approved by classification societies (ABS, DNV, LR, etc.).
