Principal Features |
| |
| HAYNES® HR-120® alloy is a solid-solution-strengthened heat-resistant alloy that provides excellent strength at elevated temperature combined with very good resistance to carburizing and sulfidizing environments. Its oxidation resistance is comparable to other widely used Fe-Ni-Cr materials, such as alloys 330 and 800H, but its strength at temperatures up to 2000°F (1095°C) is significantly higher, even in comparison to Ni-Cr alloys. The alloy can be readily formed hot or cold, and is commonly welded using HAYNES 556® filler wire. |
Applications |
Applications include those which require high strength combined with good resistance to carburizingand sulfidizing environments such as the following:
• Bar Frame Heat Treating Baskets |
• Radiant Tubes |
| • Wire Mesh Furnace Belts and Basket Liners |
• Cast Link Belt Pins |
| • Muffles, Retorts |
• Recuperators |
| • Heat Treating Fixtures |
• Fluidized Bed Components |
| • Waste Incinerators |
|
|
Heat-Treatment |
| HAYNES HR-120 alloy is furnished in the solution annealed condition, unless otherwise specified. Depending on the product form, the alloy is solution annealed at a temperature ranging from 2150 to 2250°F (1175 to 1230°C) and rapidly cooled. |
