Swedish Steel Yachts (SSY) has built a new stainless steel boat named “Elvira” using Outokumpu duplex stainless steel. This innovative boat is constructed completely out of stainless steel and can withstand harsh winter weather conditions.

This boat measures 10.5m in length and was built in Gävle, Sweden. Outokumpu supplied around 5t of its super duplex 2507 stainless steel, from its Swedish units in Avesta, Degerfors and Nyby for constructing the boat.

Commonly boats are produced using glass fiber or carbon steel which requires a lot of maintenance in the form of painting. With the use of stainless steel, no maintenance activities are required. Additionally, thanks to the high strength of duplex, considerable weight savings in the boat structure were achieved since thinner material could be used.

SSY follows a patented construction process, which was used along with the super duplex stainless steel grade 2507. This allowed the fabrication of the boat’s hull to be very thin, without affecting its strength. When powerful waves put pressure on the boat’s hull, it moves controllably, due to the specific type of construction which enables progressive flexibility.

Håkan Rosén of SSY, stated that the company succeeded in building a boat completely out of stainless steel, while honoring the Gävle region’s shipbuilding history.

This stainless steel boat made its maiden voyage on the 27 July 2014.
