To quote a now permabanned member...that's utter bollocks.
Yes, all of those waters are "mineral hungry", they will chew the concrete lining off concrete lined pipes to elevate their hardness...but inside metal receptables, no, they won't eat them.
Power stations we use deionised water inside the boilers and feed system, purified with ion exchange, polished with ion exchange, and ultimately as the water is recirculated through the boiler and turbine many many times...distilled.
Corrosion rates are low, unless air gets into the system...oxides need oxygen.
If we used tap water or rainwater, we'd have scaling as well as corrosion, and intergranular corrosion.
People used tap water forever, demineralised/deionised/distilled is best practice for coolant longevity.
