Haynes HR-120 (UNS N08120, ASTM B408, DIN 2.4854) alloy offers superior performance beyond traditional Fe-Ni-Cr materials such as alloys 330 or 800H. Its strength retention in high temperature oxidizing and molten salt environments makes it ideal for heat treating baskets, radiant tubes, recovery boilers, incinerators, and turbine engine parts. This alloy also facilitates easier cold or hot forming and consistent weldability utilizing Haynes 556 filler wire, reducing fabrication costs and downtime.
OEM manufacturers, hardware suppliers, and plant maintenance teams have fast, assured access to authentic HR-120 bars, complemented by trusted supplies of Haynes HR-120 Round Bars and Inconel 718 Round Bars for diverse needs.
By choosing Haynes HR-120, stakeholders in chemical, marine, oil & gas, pharma, and power sectors dramatically reduce operational risks while optimizing plant lifecycles, thanks to its proven strength and resistance combined with worldwide certified availability.
High-quality Haynes HR-120 Round Bars ready for industrial use.

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: heat treat baskets, radiant tubes, muffles, retorts, fluidized beds, waste incinerators
- Marine: turbine engine parts, recuperators, heat exchangers exposed to carburizing gases
- Oil & Gas: furnace parts, combustion chambers, hot section engine components
- Pharma: sterilizers, reactors needing high heat and carburization resistance
- Power: heat treat furnace fixtures, incinerators, thermal processing baskets
- Hardware/OEM: wire mesh belts, cast pins, basket liners, heat treating fixtures
