Alloy 825 is also often used where oxidising and non-oxidising hot acids come into contact with the metal. Markets include pollution control, metal cleaning and scaling, oil and gas and marine applications.

Typical end uses include:

  • heating coils
  • tanks
  • baskets and chains in sulphuric acid pickling plants
  • heat exchangers in chemical production applications.
  • sea-water-cooled heat exchangers
  • offshore product piping systems
  • pollution-control equipment components
  • oil and gas well piping
  • nuclear fuel reprocessing components.

“We are not the biggest steel distributor around, but have differentiated ourselves by focusing on service, reliability and trying to find ways of helping customers rather than by just supplying metal – conversion, holding specific stock for quick delivery and consignment stock”
