Heat resistant stainless steels provide:

  • Scaling resistance at high temperatures
  • High sulfur applications where high strength is not required
  • Corrosion resistance at high temperatures (moderate strength)
  • Resistance to thermal fatigue and shock induced by severe temperature cycling

Common applications for heat-resistant stainless steels include:

  • Ore roasting furnace parts, rabble arms and blades, steel mill furnaces
  • Salt pots
  • Grate bars
  • Tube supports and beams in oil refinery heaters
  • Scaling resistance at high temperatures
  • Radiant tubes
  • Oxidizing and carburizing atmospheres
