Incoloy 800 (UNS N08800 / W.Nr. 1.4876) Nickel-Iron-Chromium Alloy Round Bar

• Incoloy 800 nickel‑iron‑chromium heat‑resistant round bar, UNS N08800 / W.Nr 1.4876, conforms to ASTM B409 bar specification
• Ni‑Fe‑Cr‑Al‑Ti solid‑solution alloy, excellent oxidation & carburization resistance for high‑temperature furnace environments, typical service up to 600 °C
• Great resistance to chloride‑induced stress‑corrosion cracking(SCC) in hot aqueous brine media, superior to conventional austenitic stainless steels
• Titanium‑aluminium addition stabilizes microstructure, reduces intergranular sensitization risk after welding
• Non‑hardenable by quenching or aging; supplied in solution‑annealed soft state for full‑range CNC fabrication
• Custom diameter, length & full‑scope CNC turning, milling, threading per customer CAD/PDF drawings
• Premium raw stock for industrial furnace fixtures, heat‑exchanger components, petrochemical equipment and high‑temperature rotary hardware

This series of Incoloy 800 round bars are manufactured by hot rolling, forging or cold‑drawing, followed by solution annealing and water quenching to obtain homogeneous single‑phase austenitic microstructure. Standard delivery is soft solution‑annealed blank ready for rough‑and‑finish CNC machining.

Incoloy 800 (UNS N08800 / 1.4876) is widely‑used nickel‑iron‑chromium heat‑resistant solid‑solution alloy. It provides reliable anti‑oxidation, anti‑carburization performance under high‑temperature gaseous atmosphere, and meanwhile delivers good aqueous corrosion resistance including chloride SCC resistance. Note Incoloy 800 is designed for service below 600°C; select upgraded Incoloy 800H / 800HT when higher‑temperature creep‑rupture strength is required. Widely processed into furnace fixture bars, heat‑exchanger shafts, petrochemical reactor internals and high‑temperature fasteners for heat‑treatment furnaces, petrochemical, power‑plant and thermal‑processing industries.

• Solid‑solution‑strengthened Ni‑Fe‑Cr austenitic alloy, cannot gain hardness via quenching or aging heat‑treatment
• Balanced chromium‑aluminium‑titanium composition offers outstanding oxidation and carburization resistance for furnace atmosphere
• High nickel‑iron matrix effectively prevents chloride stress‑corrosion‑cracking in hot brine and high‑chloride water environments
• Ti‑Al elements stabilize grain boundaries, minimize intergranular‑corrosion risk after welding, acceptable for as‑welded assemblies
• Good ductility and machinability under solution‑annealed condition, compatible with conventional welding processes
• Reminder: Not optimized for long‑term creep load above 600 °C; choose 800H / 800HT for >600 °C creep‑critical applications
