Tech Center 2025-07-29 7
эп202(GH4202) is a Ni-Cr-based precipitation-strengthened deformable superalloy with a working temperature range of -253℃ to 800℃. Approximately 4% w(AI+Ti) was added to the alloy to form the γ’ aging strengthening phase, about 9% w(W+Mo) was added for solid solution strengthening, and a small amount of boron and cerium elements were added to strengthen and purify the grain boundaries. The alloy has excellent comprehensive mechanical properties and a stable microstructure. It has high corrosion resistance and oxidation resistance, as well as excellent resistance to oxygen-rich erosion. The alloy has excellent welding performance and is a typical multi-purpose high-temperature alloy material. The main products include bars, forgings, plates, tubes and wires, etc.
The density ρ of эп202(GH4202) is 8.36g/cm³.
