Heat exchanger material
Thread Content
The heat exchanger is made of 316L stainless steel; I wonder whether the higher the chromium content in stainless steel, the better, or if there is an upper limit
Of course, more isn’t always better; there is a maximum limit

You can just buy products made from standard-grade materials; nickel and molybdenum are the ones that play a key role in corrosion resistance, while chromium generally contributes to strength.
Which literature did you read in which it was stated that nickel and molybdenum have anti-corrosion properties? Have you seen the principles of stainless steel corrosion resistance? I hope you take a good look at it.
Don’t worry about the chromium content in the pipes sold to you having no limit – are they stupid? That costs money. The content of alloying elements controlled by most material manufacturers is slightly higher than the lower limit of the standard value.
