When engineers search Inconel 600 vs Inconel 625 for heat exchanger tubing, they are rarely looking for a generic alloy list. They are usually trying to prevent the expensive kind of failure: tube leakage after a few shutdowns, under-deposit attack near the tubesheet, or an over-specified material package that raises cost without adding real service life. Both are nickel-based alloys. Both outperform common stainless grades in severe duty. But in exchanger service, they are not solving the same problem. At the metallurgical level, Inconel 600 is a Ni-Cr-Fe alloy built around high nickel content, good oxidation resistance, and strong resistance to chloride-ion stress-corrosion cracking, caustic media, and high-purity water.
