Material Number Material Name Material Number (single) Standard Scope Standard Status Country Successor VDA 231-106 classification Application temperature [°C]
1.4742 (DIN EN 10095 : 1999-05) X10CrAlSi18 1.4742 DIN EN 10095 : 1999-05 DIN EN 10095 : 1999-05 replaced by DIN EN 10095 : 2018-12 Replaced Germany X10CrAlSi18 1.1.2 ≤ 900 1)
1) Remark: The material X10CrAlSi18, mat. No 1.4742 is non-scaling up to max. 1000°C (highest application temp. in air). The steel is resistant to oxidizing, sulfureous gases and shows mean resistance in reducing and carburizing gases. Application for oven components, gadgetries and for single parts of mean mechanical load.
