Nickel Iron Chrome (Ni-Fe-Cr) Alloys. This group includes grades HX and HW.
Description
These high-temperature stainless steel have the highest nickel content (around 60%) in the high-temperature family.
Properties – Why select this material
- HX and HW provide the highest carburization resistance of the standard alloys.
- Good oxidation resistance.
- Good thermal shock resistance.
Some Typical Application Types
- Electrical heating elements
- Hearths
- Muffles
- Quenching fixtures
- Containers for molten lead
Nickel Chrome Iron (Ni-Cr-Fe) Alloys.
Description
This group includes proprietary alloys loosely in the range of 45% Ni and 30% Cr with the balance of iron sometimes diminished by additions of tungsten and cobalt.
Properties – Why select this material
- Very high strength.
- High-temperature applications up to 2300°F – 2400°F/1260°C – 1320°C.
- Good oxidation resistance.
Some Typical Application Types
- Hydrogen reformers
- Tube supports and hangars
- Steel reheat furnaces
