At a medium temperature of 100 degrees Celsius, with 99% water and 1% acetic acid and hydrocyanic acid, will 316L metal suffer from corrosion?

Mixed acid – I wonder too whether the client will conduct hanging slice tests at various concentrations

The actual situation now is that corrosion is occurring, but it’s not clear whether it’s hydrocyanic acid that is causing corrosion of the stainless steel, or if there are other reasons behind it

What device is it? What’s the pressure? If it is a heat exchanger, graphite heat exchangers are recommended.

In comparison, hydrofluoric acid is the main factor causing corrosion of 316L. Under such operating conditions, non-metallic materials can be considered as the material for heat exchangers.

Are 316L also used for the inlet and outlet pipes of the pump? Is there any corrosion?
