About UNS S30815 (AISI 309S)

UNS S30815 corresponds to AISI 309S, a stainless steel designated for its high chromium (23–25%) and nickel (12–15%) content. This composition delivers excellent resistance to oxidation and scaling at elevated temperatures, making it ideal for industrial heat exchangers, furnace equipment, and refractory applications. The “S” indicates a low-carbon grade for enhanced weldability.
