Wednesday 29th November 11:30 a.m
Hosted by: Jacko Aerts, DSM, the Netherlands
Duplex stainless steels (DSS) show superior corrosion resistance compared to standard austenitic grades. This is especially the case in chloride-containing environments where many austenitic grades are failing due to stress corrosion cracking.
However, even DSS have their limitations, for example, when a substantial chloride load is combined with a low-pH environment.
Understanding the limits of application of DSS grades is therefore crucial to prevent unexpected – and costly – failures.
The presentations in this interactive session will address both the application limits as well as how these are linked to the specific material structure of DSS.
These presentations will be shorter than those given in the preceding session on the same subject, to allow for more comments and questions from the audience.
Following the presentations, delegates will be invited to engage in further discussion and are encouraged to bring forward their own cases for comments by the panel and fellow delegates.
