Which one is more resistant to chloride ions: cast iron, carbon steel, or stainless steel?
I’m not sure what you want to know. There are too many stainless steel grades, and it’s useful to have a clear idea: generally speaking, stainless steel is superior to carbon steel, which in turn is superior to cast iron; cast iron is essentially scrap metal
Cast iron – carbon steel, stainless steel, roughly that’s it.
Check the concentration! I think cast iron is better!
Do not mislead people – cast iron is not scrap metal. Since the operating conditions are not specified, it’s impossible to make a comparison. There is no such thing as a general standard in this case; cast iron is not necessarily inferior to stainless steel. It should be noted that austenitic stainless steel is not resistant to chloride ions – it is only resistant at levels of 50 ppm or below Check it – there are many grades of cast iron liquid.
Yes, this is the usual case; austenitic stainless steels are indeed a rather special category
