Principal Features<\/h2>\n\n\n\n

HAYNES\u00ae<\/sup> HR-120\u00ae <\/sup>alloy (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\u00baF (1095\u00baC) 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\u00ae<\/sup> 556\u00ae<\/sup> filler wire.<\/p>\n\n\n\n

Applications<\/h3>\n\n\n\n

Applications include those which require high strength combined with good resistance to carburizing and sulfidizing environments such as the following:<\/p>\n\n\n\n

Heat Treatment<\/h3>\n\n\n\n

HAYNES\u00ae<\/sup> HR-120\u00ae<\/sup> 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 \u00b0F (1175 to 1230 \u00b0C) and rapidly cooled.
