Safety Chain Anchor:
- Size: Typically 12.5 mm to 76 mm diameter
- Grade: Grade 2, Grade 3, or High-Tensile (HT) steel
- Material: Forged or cast steel, often galvanized for corrosion resistance
- Working Load Limit (WLL): Varies by size and grade (e.g., 1.5 to 200 tons)
- Breaking Strength: 4-6 times WLL depending on grade
Anchor Chains:
- Size: 13 mm to 152 mm diameter (common marine sizes: 19 mm to 76 mm)
- Grade: Grade 2, Grade 3, or High-Tensile (HT) steel (e.g., U2, U3, K3, K4)
- Material: Carbon steel or alloy steel, often hot-dip galvanized
- Viscosity: N/A (chains are solid, no fluid properties)
- Buoyancy: Negative (submerged weight ~2.5-3.0 times in air due to water displacement)
- Proof Load: 50-70% of breaking strength (e.g., 32 mm G3 chain: ~1,250 kN proof load)
- Breaking Strength: Varies by size/grade (e.g., 22 mm G3 chain: ~690 kN)
- Stud Link: Common for marine applications (studs prevent chain kinking)
