The Home of HASTELLOY® and HAYNES® alloys

Principal Features

HAYNES® HR-120® (UNS # N08120) 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 ºF (1095 ºC) 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.
