Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification Application temperature [°C]
1.4823 (DIN EN 10295 : 2003-01) GX40CrNiSi27-4 1.4823 DIN EN 10295 : 2003-01 Supersedes DIN 17465 : 1993-08 Valid Germany GX40CrNiSi27-4 1.1.2 ≤ 1100 1)
1) Remark: According to DIN EN 10295 : 2003-01, the highest application temperature in air is 1100 °C for the material GX40CrNiSi27-4, material number 1.4823 (the former G-X 40 CrNiSi 27 4 according to DIN 17465 : 1977-09). The following is valid for the comparable DIN-material: Application for heat-resistant castings, e.g. movable furnace parts and firing parts, gate valves, rails, rolls, burner nozzles, moulds for glass. Also especially suitable for furnace parts that, under higher stress, are meant to be still resistant to gases containing sulphur, such as superheater mountings, tong-type drifts, annealing retorts and similar parts. Durability: - with an oxidizing combustion atmosphere: 1100 °C, - with a reducing combustion atmosphere: 1100 °C, - with oxidizing gases containing sulphur: 1100 °C, - with reducing gases containing sulphur: up to 1080 °C.
