Voith has been awarded a significant contract to supply two stainless steel Francis runners for the Santa Uxía hydropower station in Galicia.
By Joanne McIntyre, Stainless Steel World
Santa Uxía hydropower station is equipped with two vertical Francis spiral turbines, and the two new runners will be delivered as part of a broader modernisation effort, improving the station’ s operating range without requiring any changes to the existing technical layout. The runners will be manufactured in martensitic stainless steel grade 1.4313( also known as grade13.4). Voith’ s scope also includes dismantling, installation support, and refurbishment of selected components. It aims to increase hydraulic efficiency, reduce wear, and extend the lifetime of the machines while maintaining compatibility with the existing infrastructure. While several companies competed for the job, Voith was selected not only based on price, but because it best understood the plant’ s operational needs.“ Voith was the one who best understood our requirements,” said Federico Rodríguez Trillo( Director División de Energía in XEAL) during final negotiations“ This order is a strong signal of customer confidence and sets the stage for future cooperation,” says Aitor Aierbe, Head of HyService and Sales VHTO.“ We’ re already exploring digital extensions and other service opportunities at Santa Uxía and beyond.”

What is grade 1.4313?
Martensitic stainless steel grade 13.4, commonly referred to as 1.4313 or X3CrNiMo13-4 and written as UNS S41500 according to the UNS norm, is a high-hardenable martensitic stainless steel known for its exceptional toughness, corrosion resistance, and good weldability compared to other martensitic grades. It is specifically designed to withstand cavitation and corrosion in hydraulic and industrial applications.
