Therma 22FCTM stainless steel: ready to power the hydrogen economy

Download a new guide for valuable insights and technical specifications.

Therma 22FC™ is Outokumpu's customized solution to the emerging solid oxide electrolyzer cell (SOEC) and solid oxide fuel cell (SOFC) technology. It’s a stabilized nickel-free, high-chromium ferritic stainless steel, offering a perfect match for SOFC and SOEC stacks.

Therma 22FC™ combines:

Durability to ensure reliable operation over a long service life
Low thermal expansion coefficient (TEC) compatible with ceramic oxide components and sealing materials
Corrosion resistance in a dual atmosphere, resistance to hydrogen and other fuel gases such as methane
Low and stable electrical resistivity
High creep resistance at high temperatures, suitable for cell stacks
Resistance to evaporation of elements like chromium
Good forming properties

Outokumpu’s new guide provides a detailed overview of Therma 22FC™, including its chemical composition, physical properties, forming and welding behavior and application in interconnector plates.
