A cost step between stainless and full nickel alloys — see the grade table below for full datasheets and equivalents within this family.
See All Grades ↓Incoloy is a family of nickel-iron-chromium alloys — higher iron content than Inconel, which lowers cost while still delivering meaningful improvement over stainless steel for high-temperature carburizing environments and moderate sour or acid service. It typically sits as a cost and performance step between duplex/stainless and the full Inconel or Hastelloy families.
Incoloy 800/800H is the common high-temperature grade for carburizing and oxidizing atmospheres; Incoloy 825 is the common corrosion-resistant grade for sour service and moderate acids, often considered alongside Inconel 625 where its lower cost and adequate performance are sufficient.
| Grade | Designation | Best For |
|---|---|---|
| Incoloy 800/800H (datasheet in development) | UNS N08800 / N08811 | High-temperature carburizing and oxidizing service |
| Incoloy 825 (datasheet in development) | UNS N08825 | Sour service and moderate acids, cost step below Inconel 625 |
When the sour or acid service is moderate rather than severe — 825 offers adequate resistance at a lower cost than 625, and is often the more economical choice when full 625 performance isn't required.
Yes — 800H has controlled carbon content and grain size specifically for improved high-temperature creep strength, and is the preferred variant for sustained high-temperature structural service.
