The composition of Stainless Steel 309H Pipes includes iron, chromium (23–25%), nickel (12–15%), and a higher carbon content (0.08–0.15%), along with trace amounts of manganese and silicon. The increased carbon content boosts tensile and creep strength at elevated temperatures, while the austenitic structure contributes to excellent toughness, ductility, and thermal stability. Mechanically, these pipes are known for their high tensile and yield strength, outstanding creep resistance, and remarkable dimensional stability, even when exposed to extreme temperatures and oxidizing conditions for extended periods.
