• Superior oxidation, carburization & nitridation resistance up to 1095°C high-temperature cyclic service
• Stable performance in hot concentrated caustic alkali, dry chlorine & hydrogen chloride gas media
• Uniform continuous grain flow from seamless ring rolling, uniform mechanical property all over blank
• Excellent weldability without post-weld heat treatment requirement, no intergranular sensitization
• Custom OD, ID, height & full CNC turning/milling/grooving per customer CAD/PDF drawings
• Wide service range from cryogenic to high temp, ideal furnace & nuclear pressure vessel components

This series of Inconel 600 forged rings are produced via open-die forging and radial-axial seamless ring rolling process. After precise solution annealing and full stress relief heat treatment, the ring forms continuous compact metal fiber without internal lamination or crack defects.

Inconel 600 is classic Ni-Cr-Fe solid-solution superalloy without precipitation hardening elements. Its ultra-high nickel matrix fundamentally avoids chloride SCC failure, while chromium element forms dense anti-oxidation film under high temperature. Compared with duplex and austenitic stainless steel, it performs far better in hot alkali and high-temperature furnace environments. Forged ring blanks are widely machined into furnace flanges, nuclear tube sheet rings, chemical reactor support rings and heat equipment annular components for heat treatment, nuclear power, chlor-alkali and aerospace industries.

• Single-phase non-magnetic nickel-chromium iron solid-solution alloy, non-age hardenable
• 72% minimum nickel content completely resists chloride induced stress corrosion cracking
• 14–17% chromium offers outstanding anti-oxidation & anti-carburization at high temperature
• Stable service in hot concentrated NaOH/KOH, dry Cl₂ and HCl gas environments
• Uniform mechanical performance from cryogenic -196℃ up to 1095℃ continuous operation
