Which alloy is similar to GH4098?

GH4098 alloy is similar to GH98 alloy in that they are both Ni-Cr-based precipitation hardening deformed high-temperature alloys.

Both alloys share the following characteristics:

Long-term operating temperature: The long-term operating temperature of both alloys can reach 1000 degrees Celsius.
Strengthening mechanism: Solid solution strengthening is performed by adding elements such as tungsten, molybdenum, chromium and cobalt, and elements such as aluminum, titanium and niobium are added at the same time to form a γ' phase precipitation strengthening phase. In addition, trace amounts of boron and cerium elements are added for grain boundary strengthening.
Performance: It has high room temperature and high temperature strength, as well as excellent oxidation resistance. Both have good thermal processing and welding properties.
Chemical composition: Although the specific chemical composition ratios may vary, the basic element types are similar, including carbon, chromium, nickel, cobalt, tungsten, molybdenum, aluminum, titanium, iron, niobium, cerium, boron, etc.
Overall, GH4098 and GH98 are often considered similar alloys due to their similarities in composition and properties. However, the specific choice of alloy needs to be determined based on the actual application needs and specific conditions. For example, operating temperature, stress conditions, processing requirements, etc. may affect the selection of alloys.
