This series of Inconel 718 solid and hollow shafts are manufactured by hot rolling + seamless piercing cold drawing forming. Standard supply base state is Solution Annealed Condition A soft blank for easy CNC machining; customers can perform standard double aging treatment to achieve ultra-high tensile and creep strength.
Inconel 718 is the most widely used precipitation hardening nickel superalloy. Its unique niobium precipitate strengthening mechanism delivers superior high-temperature creep resistance unmatched by Inconel 625 solid solution alloy. Solid shaft serves high-load solid spindles, while seamless hollow shaft greatly reduces solid bar deep boring workload for tubular rotary parts. Widely processed into aircraft engine turbine shafts, subsea rotary valve stems, nuclear reactor control spindles, sour oilfield downhole shafts and high-temperature furnace roller blanks for aerospace, offshore energy, nuclear power and petrochemical industries.

Double aging delivers sustained high tensile & creep strength up to 704°C, far superior to solid-solution nickel alloys for long-cycle hot rotating equipment.
Pass NACE MR0175 standard, fully resist sulfide stress cracking, suitable for offshore subsea & H₂S oil well shaft parts.
Maintain excellent ductility from cryogenic to medium high temperature, no brittle failure risk under alternating cold-hot working conditions.
Seamless hollow shaft avoids deep boring on solid bar, greatly reduces raw material waste and CNC processing time for tubular spindles.
No welding hot cracking; aging heat treatment can be performed after full assembly of welded shaft components.
We provide integrated hot rolling & seamless piercing hollow shaft production, full custom CNC machining per customer CAD/PDF drawings:
We supply Inconel 718 solid & hollow shaft blanks plus fully machined finished spindles for aerospace, offshore, nuclear and chemical global industrial clients.
Mill Test Certificate EN 10204 3.1 can be issued and delivered together with shipment documents before delivery.
- Inner: Independent anti-rust plastic sleeve + waterproof film full wrap for surface protection
- Outer: Reinforced fumigated wooden pallet with separation strips to prevent scratch & bending deformation
- Custom heavy-duty export packaging for extra long/large-diameter shafts available upon request
Normally 10 – 45 working days after receiving advance payment. Exact lead time depends on shaft type (solid/hollow), diameter, length, order quantity and custom aging/machining requirements.
