Description

NiCr23Fe 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. processing properties: formability: good weldability: satisfactory machinability: good (solution annealed condition)

This material data has been provided by WIAM.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
