At a cutting-edge chemical refinery, heat exchangers repeatedly failed under prolonged high-temperature exposure, forcing costly shutdowns. Switching to Haynes® HR-120 Sheets (UNS N08120), a nickel-based high-temperature alloy designed for exceptional creep resistance and strength retention up to 1093°C, radically improved uptime and durability. This solution emerged as a game-changer across chemical, oil & gas, marine, pharma, and power generation sectors seeking reliable alloys battling extreme thermal and corrosive stresses.

Applications & Benefits
Why this grade
Haynes® HR-120® is an iron-nickel-chromium alloy rather than a nickel-base one, which makes it the lower-cost option in the range. It delivers creep strength competitive with far richer alloys at temperatures around 1090°C, so it is specified for industrial furnace and waste-incineration hardware where alloy cost per tonne is part of the decision.
- Chemical: High-temperature reactor internals, heat exchangers resisting carburization and sulfidation
- Oil & Gas: High-strength fasteners, bolting, and flanges requiring creep resistance and corrosion stability
- Marine: Exhaust gas components and turbine blades exposed to harsh thermal cycling
- Pharma: Sterilization chambers and kiln components needing thermal stability
- Power Generation: Combustion liners, gas turbine vanes, and boiler tubing for ultra-supercritical plants
- Fabrication & Supply: Precision-cut sheets and shim stock for demanding OEM and hardware applications
