Super High Chromium-Nickel Heat-Resistant Sheet, Specifically for Industrial Furnace Linings, High-Temperature Heat Treatment Equipment, and Radiant Tubes
| Element | Content (%) | High-Temperature Role |
|---|---|---|
| Cr (Chromium) | 24.0–26.0 | Forms dense Cr₂O₃ film, blocking oxygen diffusion; oxidation rate ≤0.01mm/100h. |
| Ni (Nickel) | 19.0–22.0 | Stabilizes austenitic structure, enhances high-temperature strength and toughness; elongation ≥15% at 1000℃. |
| Si (Silicon) | ≤1.5 | Promotes SiO₂ glass phase formation, fills oxide film pores, reduces oxidation rate by 30%. |
