Why C276 for Heat Exchangers?
This material is selected when standard stainless steels (304/316) or even higher grades like Alloy 625 or 825 fail. It offers:
Uniform Corrosion: Resistant to a wide range of aggressive chemicals, including sulfuric acid, hydrochloric acid, wet chlorine, formic and acetic acids.
Pitting & Crevice Corrosion: High Pitting Resistance Equivalent Number (PREN) ensures survival in chloride-laden environments (seawater cooling, brine, flue gas desulfurization).
Stress Corrosion Cracking (SCC): Highly resistant to chloride-induced SCC, which is a common failure mode in 300-series stainless steel heat exchangers.
Fabrication: It is readily cold worked (bent, U-bent, rolled) and welded.

Critical Testing (Beyond ASTM B622)
For heat exchanger service, buyers often add:
Positive Material Identification (PMI) – 100% of tubes to verify alloy composition.
Eddy current testing (ET) – Mandatory in many specifications (e.g., TEMA “R” class) to detect through‑wall defects.
Flattening & flange tests – To verify ductility for tube expansion.
Intergranular corrosion test (ASTM G28 Method A) – Confirms the low‑carbon stabilization is adequate, especially if the tubing will be exposed to sensitizing temperatures during welding.
Application:
Flue Gas Desulfurization (FGD): Reheaters and quench nozzles in coal-fired power plants.
Chemical Processing: Handling sulfuric acid, hydrochloric acid, and phosphoric acid.
Pharmaceutical: High-purity environments where contamination cannot be tolerated.
Offshore Oil & Gas: Seawater heat exchangers, particularly in topside facilities where chloride corrosion is extreme.
Waste Treatment: Evaporators and crystallizers.
