Stainless steel for structural design
Stainless steel follows similar design rules that exist for carbon steels. Where differences exist these are well-documented and for European projects can be found in Eurocode 3 EN1993-1-4, which describes the supplementary rules to consider in the behavior of stainless steels.
Stainless steel delivers a modern aesthetic, maintains long-lasting visual appearance and offers designers more freedom to propose slender, more elegant structures thanks to high strength structural duplex stainless steels.
Choosing stainless steels minimizes maintenance costs since there is no need for protective paint coating. Stainless steel boasts a high level of durability, and thanks to its high strength, quantity and cost of materials is reduced. Using Outokumpu stainless steel lowers the carbon footprint and environmental impact in Life Cycle Analysis.
How to choose the right duplex grade
While all duplex steels have a similar high strength, the grades within the family have different levels of corrosion resistance and should be selected to match the environmental conditions. You can find more guidance in EN1993-1-4 2015, Annex A.
