Materials selection for any piece of equipment or a process system is rarely a simple task, unless you are exactly replicating something successful. Often engineers will have a checklist to help them narrow down the choices, eliminating groups of materials that are not suitable for various reasons. Austenitic 300 series stainless steels containing 7-35% nickel will have most if not all of the boxes checked for being suitable where a stainless steel is desired.
Awareness about robustness and durability of bridge design has grown since Morandi’s time. The new San Giorgio Bridge (its successor) in Genoa was designed by Renzo Piano and inaugurated in 2020.
While it may require an initial higher investment when compared with other materials, stainless steel’s unique properties deliver long-term performance and economic benefits including minimum downtime, reduced maintenance costs and reduced environmental impacts.
New advances in the use of Artificial Intelligence have the potential to speed up the process of alloy development.
