What material should be used for the stirrer in a reaction medium containing dilute sulfuric acid at 250 degrees Celsius to ensure corrosion resistance? Thank you.

Zirconium materials – Hastelloy probably won’t be able to withstand it
The sulfuric acid concentration and the components of the suspension are unknown, making it difficult to make a choice! And when stirring at 250°C, what is the pressure in the container?
More detailed operating condition parameters are required
904L stainless steel can be considered; this type of stainless steel is resistant to corrosion by dilute sulfuric acid
Dilute sulfuric acid, what is the concentration? If the temperature
It is necessary to know the sulfuric acid concentration and whether other mixed acids are present in order to select the appropriate material, which makes it difficult to make a choice.
If fluoride ions are not present, glass-lined material can be considered.
