White Iron

White Irons

White Iron refers to a group of cast iron materials characterized by their high chromium or nickel content, offering exceptional wear resistance, toughness, and corrosion resistance. These materials are known for their high hardness and are predominantly used in environments where abrasion, impact, and corrosion are prevalent. White Iron alloys, including Ni-Hard Iron and Chromium 12 and 25, are distinguished by their distinct compositions and mechanical properties, making them suitable for a wide range of industrial applications.

Key Features of White Iron

  • High Wear Resistance: Excellent resistance to abrasion and erosion, making it ideal for components exposed to abrasive materials.
  • High Hardness: Provides superior surface hardness, contributing to the material’s wear resistance.
  • Good Toughness: Despite their hardness, certain grades offer good toughness and are capable of withstanding impact without fracturing.
  • Corrosion Resistance: High chromium variants exhibit exceptional resistance to oxidation and corrosion, suitable for harsh chemical environments.
  • Heat Resistance: Maintains mechanical properties at elevated temperatures, making it suitable for high-temperature applications.

Common Applications of White Iron

  • Mining and Mineral Processing Equipment: Components such as crusher liners, pulverisers, and grinding mills.
  • Cement Industry: Wear parts like crushers, grinding mills, and conveyor systems.
  • Power Generation: Components in coal pulverisers and ash handling systems.
  • Construction and Aggregates: Excavator buckets, bulldozer blades, and rock crushers.
  • Dredging and Pumping: Dredge pumps, slurry pumps, and cutter heads.
  • Recycling Industry: Shredder hammers and wear plates.
  • Aerospace Components: High-strength, corrosion-resistant parts such as turbine blades and casings.
  • Marine Equipment: Propellers, shafts, and fittings resistant to saltwater corrosion.
