🔧 Duplex or AISI 316L? In the maritime world, material selection makes all the difference! ⚓

In our latest edition of Not-So-Trivial Questions, we explain why duplex stainless steel is the smart choice for mooring and towing in harsh marine environments. 🌊

✅ Superior resistance to localized corrosion
✅ Twice the mechanical strength of 316L
✅ Service life up to 25 years
✅ Less maintenance = lower long-term costs

At Posidonia, we use duplex for our SHHP/VHHP anchors and other critical deck components. For us, it's not just a technical upgrade — it's a commitment to safety, reliability, and operational excellence. 💪

🔧 Enhanced Control and Quality with Posidonia's New CNC Machine

We’ve just upgraded our in-house capabilities with a new gantry-type CNC milling machine – the SELCA 3045 – with a 3000 x 1000 x 1200 mm axis range.

It’s already at work machining 3,500 kg PTW® HHP anchor shanks in solid Duplex stainless steel – a marine-grade material superior to AISI 316L. The PTW® anchor offers 25% weight reduction compared to traditional mass anchors, boosting efficiency and reducing fuel consumption.

This new CNC gives us full control over machining quality, tighter tolerances, and more reliable lead times for custom marine and naval components.

📍 Made in Italy, certified by IACS & NAVY authorities.

⚓ Continuous chain or Kenter link?
That’s one of the most common questions we get from our clients!

🔹 The Kenter link is designed to join two chain lengths of the same size, making it possible to adjust the chain length as needed.
🔸 But keep in mind: due to its bulkier shape, it might not pass smoothly through the windlass.

👉 The right choice depends on your vessel's setup and anchor configuration.

At Posidonia, we provide:
✅ Grade 2 and Grade 3 anchor chains
✅ Certified Kenter links
✅ Finishes: galvanized, tarred, stainless steel, low magnetic permeability, and mirror-polished

💬 Not sure which setup suits you best?
