1.4762 (DIN EN 10095 : 2018-12) X10CrAlSi25 1.4762 DIN EN 10095 : 2018-12 Supersedes DIN EN 10095 : 1999-05 Valid Germany X10CrAlSi25 1.1.2 550 - 1150 1)
1) Remark: The ferritic heat-resistant steel X10CrAlSi25 is resistant to the effects of hot gases and products of combustion at temperatures above 550 °C. It is scaling resistant in air up to 1150 °C (highest application temperature in air). The steel is highly resistant to oxidizing, sulfureous athmosphere. Low resistance in nitrogenous, oxygen deficient gases. The temp. limit in permanent operation accounts for 1000 °C: The steel has 3 embrittlement spans: 475 °C, 600 to 850 °C and above 900 °C. Application for oven components, gadgetries, annealing boxes for components of low mechanical load.
