X15CrNiSi25-4
1.4821Heat-resistant duplex (austenitic-ferritic) stainless — 25Cr-4Ni-1.5Si. Si addition improves oxidation resistance at high temperature. Used for furnace components, burner nozzles, heat treatment fixtures, and kiln supports operating at 800-1000°C. Higher strength than fully austenitic heat-resistant grades at intermediate temperatures due to duplex structure.
