Description

2.4360 has good mechanical properties from sub-zero temperatures up to about 550 °C. This alloy is one of the few metallic materials which can be used in contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. It has been a standard material for salt plants for many years.

Equivalent Materials

This material data has been provided by Hempel Special Metals.

"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.

Application areas

2.4360 is a single-phase solid-solution nickel-copper alloy with excellent corrosion resistance to a wide range of media. Typical applications include:


  • propeller and pump shafts for seawater service
  • industrial heat exchangers
  • brine heaters and evaporator bodies in seawater desalination plants
  • feed-water and steam generator tubing in power plants
  • plants for uranium refining and isotope separation in the production of nuclear fuel
  • sulphuric and hydrofluoric acid alkylation plants
  • splash-zone sheathing in offshore structures
  • cladding for crude oil distillation columns

  • Corrosion properties

    Alloy 400has outstanding resistance to neutral and alkaline salt solutions. This alloy is one of the few metallic materials which can be used in contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives and is free from chloride induced stress-corrosion cracking.
