This series of Incoloy 925 solid and hollow shafts are produced by hot rolling + seamless piercing cold drawing forming process. The standard factory supply base state is Solution Annealed Condition A soft blank for easy CNC machining; customers can perform standard aging treatment to achieve target high tensile and yield strength.
Incoloy 925 is a widely used sour-service precipitation hardening nickel alloy, integrated copper and molybdenum elements to strengthen resistance to reducing acid and chloride media. Different from high-temperature focused Inconel 718, Incoloy 925 is optimized for oil & gas downhole environments with superior anti-SCC performance and lower raw material cost. Solid shaft is applied for solid transmission spindles; seamless hollow shaft avoids heavy deep boring on solid bar, cutting processing cycle and material waste significantly. Widely machined into downhole pump shafts, wellhead valve stems, desalination equipment spindles, chemical agitator rods and marine fixture blanks for petroleum, offshore, chemical and seawater treatment industries.

NACE certified grade, stable service in high H₂S & chloride mixed downhole brine, avoid sulfide cracking failure of ordinary stainless steel.
Copper + molybdenum dual alloy design, outstanding tolerance to sulfuric, phosphoric acid and seawater brine media.
Lower nickel & niobium content, more economical for medium-temperature oilfield rotary components while retaining precipitation hardening capacity.
Seamless hollow shaft eliminates deep boring process, reduces material waste and shortens CNC processing cycle for hollow spindles.
Minimal dimensional shift during precipitation hardening, fit precision valve & pump shafts with tight tolerance requirements.
We provide integrated hot rolling & seamless piercing hollow shaft production, full custom CNC processing per customer CAD/PDF drawings:
We supply Incoloy 925 solid & hollow shaft blanks and finished machined spindles for petroleum, offshore, chemical and desalination 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 scratch protection
- Outer: Reinforced fumigated wooden pallet with separation strips to prevent bending & collision damage
- 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 demands.
