History and Development In the naval industry, bolts are subjected to extreme conditions: constant humidity, salt water and aggressive atmospheres. For this reason, the choice of materials and surface treatments is crucial to ensure corrosion resistance, safety and durability of structures. Since the first iron and steel shipyards, corrosion has been one of the main challenges. With technological progress, the industry has developed special materials and advanced treatments to extend the service life of fasteners in marine environments.
Technological Evolution
Bolts for marine use are distinguished by the use of:
- A4/A5 stainless steels (AISI 316, 318): resistant to intergranular corrosion and salinity.
- Special alloys: nickel-chromium, titanium for critical applications.
- Advanced surface treatments: hot-dip galvanising, Geomet, zinc-nickel, anti-corrosion polymer coatings to increase durability in highly aggressive environments.
- International certifications: fasteners comply with standards such as ISO 3506 to ensure specific performance in marine environments.
Modern applications
- Shipbuilding: hulls, superstructures, scaffolding, piping.
- Offshore plant engineering: oil platforms, offshore wind turbines.
- Ports and marine infrastructure: piers, jetties, quays.
In all these applications, fasteners must withstand mechanical stress, thermal cycles and corrosive agents, maintaining consistent performance over time.
