The first delivery of Outokumpu Circle Green stainless steel is expected in 2026 and will be used in the latest generation of Alstom Metropolis metro trains.

Outokumpu Business Line Advanced Materials president Rolf Schencking said: “Stainless steel is the most versatile industrial material, heavily needed for transportation solutions to reduce emissions and playing a vital part also for innovation and technological progress.

“Europe needs frontrunner companies throughout the value chain to drive the green transition forward. We are excited to take the next step with Alstom to support our customers’ decarbonisation journey. The Circle Green contract with Alstom is volume-wise the biggest for us in the mobility sector and is due to be used in a first metro train project in Europe.” 

This initiative is a response to the increasing demand for mobility solutions that also address the need for a low carbon footprint amidst growing urbanisation.
