Fasteners for the maritime industry 16 February 2023

Here, Specialinsert Srl outlines the importance of fasteners within the maritime industry and which components are the most reliable in an industry prone to harsh environments and corrosion.

Fasteners are an essential component of the maritime industry, where they are used in a variety of applications, including shipyards, boats, yachts, fishing vessels, merchant vessels, boat accessories, offshore energy systems or pipelines. In the marine industry, mechanical fasteners are often the preferred choice due to their strength and security. 

The choice of fasteners for the maritime industry

One of the main considerations when choosing fasteners for the marine and nautical industry is corrosion resistance. Salt water, in fact, is highly corrosive due to the high concentration of dissociated ions. Therefore, when choosing fastening solutions for use in the maritime sector, it is essential to focus on corrosion-resistant materials.

Austenitic stainless steels are often recommended because they have a stronger passive film. In critical situations, where even higher corrosion resistance is needed, certain surface finishing treatments such as passivation, electropolishing or special galvanic coatings can be considered.
