High-temperature alloy bar is a bar-shaped metal material used in high-temperature, high-pressure, and highly corrosive environments. It is primarily made of nickel-, iron-nickel-, or cobalt-based high-temperature alloys. It exhibits excellent high-temperature strength, creep resistance, oxidation resistance, and corrosion resistance. It is widely used in the manufacture of high-temperature structural parts, fasteners, turbine components, and other applications in the aerospace, nuclear power, shipbuilding, petrochemical, and energy industries.
Types and characteristics of high temperature alloy bars
| Alloy type | Representative brand | Performance characteristics |
|---|---|---|
| Nickel-based superalloy | Inconel 718、GH4169、GH2132、GH3044 | Excellent high temperature strength, strong oxidation resistance and corrosion resistance, suitable for the core parts of the engine |
| Iron-nickel based high temperature alloys | Incoloy 800、GH3128、GH3039 | Good hot working performance and formability, suitable for large structural parts and heat-resistant parts |
| Cobalt-based superalloy | L-605、GH5188、GH605 | Excellent thermal stability and thermal fatigue resistance, often used in aviation hot end components |
