The strength of this particular tubing comes from its specialized composition. It’s an austenitic chromium-nickel steel stabilized with titanium, which gives it outstanding resistance to sensitization and intergranular corrosion. This means it holds up exceptionally well when exposed to high temperatures, typically in the range of 800-1500°F. The “H” grade indicates a higher carbon content, providing enhanced creep resistance and superior tensile and yield strength at elevated temperatures. Essentially, this specific makeup ensures the tubing maintains its integrity and performance under sustained thermal stress, which is crucial for safety and efficiency.
