The 3B anchor chain is a high-strength, durable marine-grade chain designed for anchoring vessels securely. It features a stud link design for added strength and reliability in harsh marine environments. Commonly used in commercial and naval applications, it ensures safe mooring and anchoring.

Size: 3B anchor chain typically has a nominal diameter of 3 inches (76 mm).

Grade: Common grades for anchor chains include Grade 2, Grade 3, and High-Test (Grade 4), with Grade 3 being widely used for marine applications.

Viscosity: Not applicable to anchor chains as viscosity is a fluid property.

Buoyancy: Anchor chains are negatively buoyant and sink in water due to their high-density material.

Material: Typically made from high-strength carbon steel or alloy steel, often galvanized for corrosion resistance.

Weight: Approximate weight per unit length is around 123 lbs/ft (183 kg/m) for Grade 3.

Breaking Load: For Grade 3, the minimum breaking load is approximately 1,470 kN (330,000 lbf).

Proof Load: Typically 50% of the breaking load for testing purposes.

Finish: Hot-dip galvanized or painted for enhanced durability in marine environments.

Standards: Complies with international standards such as ABS, DNV, or ISO 1704.
