Description

G-Ni90Si is brittler than the material G-Ni95 (2.4170) and possesses increased resistance to wear. The tendency to galling at insufficiently lubricated bearing spots is low. The material possesses good corrosion-resistance to non-oxidizing mediums. It shows very good resistance to hot and concentrated caustic alkalies as well as to dry gases, e.g. chlorine. The material is applied in the chemical industry and in the food industry, for valves and fittings, in the apparatus engineering, for pumps, shut-off devices and the like. Processing properties: Weldability: not weldable.

Equivalent Materials

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.
