316L corrodes with honeycomb perforations in seawater
Thread Content
Stainless steel 316L develops perforations after just half a year in seawater, even with a plate thickness of three millimeters. Is there any similar material that can be used as a substitute?
With such severe corrosion, the material itself may not be suitable; consider other forms of protection such as painting or lining with plastic
Chloride ions in seawater are very high. To create an anti-corrosion coating that isolates seawater from the metal.
High chloride content: dual-phase stainless steel coatings may not be effective; it is recommended to use anti-corrosion coatings
Is there a specific plan for what kind of coating to use? Thank you, please recommend one
I just want to ask what materials are used in cross-sea bridges. The Hong Kong-Zhuhai-Macao Bridge is designed to last 120 years, so what kind of high-quality materials must be used?
High chloride levels in the sea mean that corrosion can be severe. Ceramic craftsmanship is quite advanced these days; using that might be better
