Hello, the solution is therefore welded flange on steel and flange adapters on cast iron. Most manufacturers offer gaskets adapted to different temperatures and different fluids. Specify the temperature: example ethylene propylene for water up to 90 degrees or polyacrylic for up to 130 degrees.
I have used silicon bronze to join dissimilar materials such as stainless to steel , iron to steel with great results when TIG applied . This application would be dependant on accessibility of course.
