Alloy HR-120 Description


Alloy HR-120 alloy is a solid-solution-strengthened heat-resistant alloy that provides excellent strength at elevated temperature, combined with 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 deg. F (1095 deg. C) is significantly higher.

Applications


Heat treating baskets
Wire mesh furnace belts and basket liners
Recuperators
Heat treating fixtures

Alloy HR-120 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.


Additional Properties


Corrosion Resistance


Refer to NACE (National Association of Corrosion Engineers) for recommendations.

Standard Wire Finishes


Extra Clean: Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”

Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications

Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation.

A soap finish is available in tempered products.
Plated: Many plating options are available.
*Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.
