Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification Application temperature [°C]
2.4851 (DIN EN 10095 : 2018-12) NiCr23Fe 2.4851 DIN EN 10095 : 2018-12 Supersedes DIN EN 10095 : 1999-05 Valid Germany NiCr23Fe 3.4 550 - 1200 1)
1) Remark: The heat-resistant nickel alloy NiCr23Fe is resistant to the effects of hot gases and products of combustion at temperatures above 550 °C. It shows favorable oxidation resistance at high temperatures due to the Al- and high Cr-content. Excellent high-temperature strength and excellent scaling resistance allow application temperatures up to 1200°C (highest application temperatures in air). Favorable resistance to carburization and nitriding. Resistance to stress corrosion in presence of chloride ions as well as to corrosion in high-purity water and alkaline media. Application for boxes, fastener, steel tubes, transpot bands, furnace sheaves in annealing furnaces, insulation inerts in ammoniac cracking plants and for catalyst-fences in nitrous acid production, components for catalytic converters, combuster of waste incineration plants, components for heat-treatment furnaces, muffles and transport sheaves for ceramic stoves, components for gas turbines, oxygen preheater in titanium dioxide production, bolts and screws for refractory anchorage as well as for flare heads.
