Objectif
Stainless steels are durable, renewable and functional materials for demanding environments, but they have the drawback that pitting, crevice corrosion or stress corrosion cracking can cause serious failures.
Materials selection today is often based on corrosion tables, which are limited to one or two parameters and rarely correspond well to demanding environments. This project will provide a new methodology for advanced multi-dimensional design curves in terms of temperature, chloride content, pH, potential, load and geometry. Field and laboratory testing will be used to evaluate the risk of fast-growing cracks developing in crevices and the safety margin needed for long-term service.
