1.4845 (DIN EN 10095 : 2018-12)	X8CrNi25-21	1.4845	DIN EN 10095 : 2018-12	Supersedes DIN EN 10095 : 1999-05	Valid	Germany	X8CrNi25-21	1.1.2	550 - 1050	1)
1) Remark: The austenitic heat-resistant steel X8CrNi25-21 is resistant to the effects of hot gases and products of combustion at temperatures above 550 °C. It is used for parts in industrial furnaces, steam boiler, petroleum plants, for thermometer sheath tubes. Best resistance to nitrogenous, oxygen deficient gases. Heat-resistance in air up to 1050°C (highest application temperature).
