The "H" is for Heat – Specifically, a Thermal Process
While people know "H" stands for "high-temperature," the specific requirement is often overlooked:
It's Not Just Chemistry: To be legitimately called 800H, the material must be solution annealed at a minimum temperature of 2100°F (1149°C). This isn't just for stress relief; it's to achieve a specific ASTM grain size of 5 or coarser.
Application
Petrochemical & Chemical Processing: Steam methane reformer furnace tubes, pigtails, transfer lines, ethylene cracking tubes.
Power Generation: Superheater and reheater tubes in fossil fuel boilers, heat recovery steam generators (HRSGs).
Industrial Furnaces: Radiant tubes, muffles, retorts, and other heat-treating equipment.
Nuclear Power: Steam generator tubing in some reactor designs (due to its corrosion resistance).
Heat Exchangers: For severe, high-temperature service.
