Rocna Anchor Swivel:
- Material: High-tensile galvanized steel or stainless steel (316 grade)
- Sizes: 6mm to 32mm (compatible with chain sizes)
- Working Load Limit (WLL): Varies by size (e.g., 6mm: ~1,000 kg, 32mm: ~50,000 kg)
- Breaking Strength: 4-6 times WLL depending on material
- Corrosion Resistance: High (galvanized or stainless steel)
- Rotation: 360-degree swivel for reduced chain twist
Anchor Chains:
- Material: Grade 30, 40, or 70 high-tensile steel (hot-dip galvanized)
- Sizes: 6mm to 32mm (standard marine sizes)
- Grade 30: Minimum breaking load ~3,000 kg (6mm) to ~250,000 kg (32mm)
- Grade 40: Higher strength than Grade 30 (~25-30% increase)
- Grade 70: Ultra-high strength (~50% stronger than Grade 40)
- Buoyancy: Negligible (steel density ~7.85 g/cm³)
- Corrosion Resistance: Hot-dip galvanized coating (~85-100 microns)
- Viscosity: N/A (solid material)
