Stainless Steel 321 and its high-carbon variant, 321H, are stabilized with titanium, which grants them exceptional resistance against sensitization and intergranular corrosion. This composition allows them to maintain their strength and integrity in high-temperature environments, typically up to around 900°C. The “H” grade offers higher creep and stress rupture properties, making it a robust choice for sustained elevated temperatures, ensuring long-term reliability in demanding service conditions.
