321/321H stainless steel sheet is a titanium-stabilized austenitic stainless steel designed for superior high-temperature performance and intergranular corrosion resistance. 321H (UNS S 32109) stainless steel plate is the higher carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification.
Key Features & Benefits
✔ Excellent Oxidation Resistance – Performs reliably in continuous service up to 900°C (1650°F)
✔ Stabilized Against Sensitization – Titanium addition prevents chromium carbide precipitation, reducing weld decay
✔ Good Formability & Weldability – Compatible with standard fabrication techniques
✔ Corrosion Resistance – Resists acids, alkalis, and chloride stress corrosion cracking (better than 304 in some environments)
