1.4845 - Austenitic, heat-resistant stainless steel / X15CrNi25-21 / AISI 310S / S31008
Description
Material 1.4845 (X15CrNi25-21 / AISI 310S) – austenitic stainless steel Properties and Applications
The material 1.4845, designated X15CrNi25-21 and commercially known as AISI 310S, is an austenitic stainless steel. It provides excellent resistance to oxidation and scaling up to about 1050 °C, combined with good corrosion resistance in aggressive atmospheres. Due to its high chromium and nickel content, 1.4845 offers superior strength and durability under elevated temperatures, making it particularly suitable for thermally stressed components. Typical applications include furnace linings, heat exchangers, exhaust systems, burner components and parts used in high-temperature equipment and plant construction. Furthermore, this steel maintains toughness and reliability even at sub-zero temperatures.
