Based on a thorough review of background information on the performance of materials in condensing gas-fired furnace heat exchangers and in similar corrosive environments, candidate materials were selected and tested on one of two identical test rigs built to provide the varying corrosive conditions encountered in an actual gas-fired condensing system heat exchanger. The 32 different materials tested in a one month screening test included: mild, low alloy, galvanized, solder coated and CaCO3 dipped galvanized steel, porcelain, epoxy, teflon and nylon coated and alonized mild steel; austenitic, ferritic, low interstitial Ti stabilized ferritic, and high alloy stainless steels; aluminum alloy anodized and porcelain coated aluminum; copper and cupronickel alloys, solder coated copper; and titanium.
