HASTELLOY® C-22® bellows have been used to replace 321 stainless steel in hot flue gases containing HF. The C-22® alloy offers over ten times extended services life and more reliable performance. |
This G-30® heat exchanger is providing excellent service in reclaiming spent sulfuric acid at 140 to 194°F (60 to 90°C). The G-30® alloy replaced graphite heat exchangers that did not provide maintenance free service. |

HAYNES® HR-160® alloy was selected for calciner tubes in a reducing atmosphere of high sulfur feedstocks at 2000°F (1090°C). |
| HAYNES® 230® catalyst support grids are used in the manufacturing of nitric acid at temperatures up to 1750°F (954°C). By virtue of its higher creep strength, thermal stability and resistance to oxidation and nitriding, 230® alloy grids significantly outperform grids made from other high-temperature alloys. |  |
