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
