Curiousity seeking input on the versions regarding Metallurgy of Stainless Steel Heat Exchangers made by SSI.
One version is all Stainless Steel and another I am told Later version is also Stainless Steel but has Mild Steel Flanges. At first glance one would assume cost of stainless steel became prohibitive, but on further research both types of steel have different strength properties(stronger in different test areas) and heat conductivity properties. Does anyone know anything on this? Any concerns other than rust? |

I had a new set in the box and Scott Detro made me check it with a magnet before he would buy them. Then he drove up with cash in fist! |

The magnet trick will tell you if the stainless steel is austenitic alloy. Ferritic aloys are magnetic and also considered as stainless, but they are not as heat resistant. http://en.wikipedia.org/wiki/Stainless_steel |
