Corrosion behavior of 316H stainless steel in molten LiF-UF4 and LiF-UF4-ZrF4 salts

Key Points

• Corrosion behavior is significantly affected by molten salt composition, with 316H stainless steel exhibiting varied resilience.
• In molten LiF-UF4, corrosion rates escalate beyond acceptable levels after 100 hours of exposure.
• Assessment using molten salts across multiple compositions highlights distinct liquidus temperatures and interaction effects.
• Findings underscore the importance of material selection for high-temperature environments, indicating a need for further investigation.
