Description and applications*
* Illustrative, not-exhaustive list
This filer wire is an austenitic stainless steel, which due to its high molybdenum content shows very high resistance to localized corrosion such as pitting and crevice corrosion, as well as to stress-corrosion. It was firstly designed for use in halide-containing environments, such as seawater.
Due to its high nitrogen content, this grade has higher mechanical strength than most of the other austenitic stainless steels.
It is recommended to perform welding by using the lowest heat input possible, as due to its stable austenitic structure, it could somewhat be more sensitive to hot cracking.
Main applications in chemical industry, seawater desalinization plants.
