This series of Incoloy 925 round bars are hot forged/rolled solid nickel alloy rods manufactured from premium UNS N09925 superalloy raw material. After solution annealing and stress relief heat treatment, the bars own uniform compact internal grain structure, stable dimensional accuracy and outstanding comprehensive mechanical & anti‑corrosion performance.
Incoloy 925 is age‑hardenable nickel alloy containing Ni, Cr, Mo, Cu and Al elements. It is specially developed for severe chloride‑rich environments such as offshore oil & gas wellhead, seawater desalination and chemical acid medium equipment. The material balances high strength and superior localized corrosion resistance, becoming the preferred structural alloy for heavy‑duty marine and energy industry components.
- Age‑hardening nickel base alloy, achieves high strength after low temperature aging treatment
- Outstanding resistance to chloride‑induced pitting, crevice corrosion and stress corrosion cracking (SCC)
- Stable mechanical performance under high pressure, seawater, brine and sour gas environment
- Good ductility, cold forming property and excellent welding performance
- Anti‑sulfide stress cracking (SSC) performance for oil & gas sour service working condition
- Suitable for long‑term continuous operation in corrosive marine and chemical processing equipment
