Applications:

The high strength variant of MP35N™ is used in the medical and aerospace industry while material produced for optimum corrosion resistance properties is primarily used in the oil & gas industry.

Applications include:

  • fasteners
  • springs
  • non-magnetic electrical components
  • instrument parts
  • valve components
  • high pressure door fittings
  • actuators
  • seals
  • shafts and other 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”
