321 alloy is developed to offer high strength at elevated temperatures. 321H also bears great creep resistance. UNS S31200 resists intergranular corrosion even after exposure to temperatures at chromium carbide precipitation range. Our ASTM SA249 Welded Tubes can easily be welded and processed by standard fabrication processes. We deliver products that are long-lasting and offer amazing usability.
