Product Highlights
  • Solid-solution strengthened Inconel 625 solid shaft, UNS N06625, EN 2.4856, fully compliant with ASTM B446 bar standard
  • Mo & Nb composite solid-solution hardening delivers high strength without aging heat treatment
  • Certified to NACE MR0175 standard, outstanding anti-SCC performance for sour oil & gas service
  • Stable mechanical & oxidation performance from cryogenic -196℃ up to 980℃ continuous operation
  • Excellent resistance to chloride pitting, crevice corrosion, mixed acid & seawater erosion
  • Homogeneous single-phase austenite matrix, no carbide precipitation after welding or thermal cycles
  • Hot rolled / cold drawn stock, custom diameter & full CNC turning, grooving, threading per CAD drawings
  • Premium shaft blank for aerospace, subsea, nuclear power and heavy chemical rotating equipment
Product Overview

This series of Inconel 625 solid shafts are manufactured via hot rolling + cold drawing forming processes. Two standard heat treatment grades are available: Grade 1 Low-Temp Solution Annealed for general corrosion service; Grade 2 High-Temp Solution Annealed for high-temperature creep resistant working conditions.

Inconel 625 is classic solid-solution nickel superalloy strengthened by molybdenum and niobium elements. It combines ultra-high mechanical strength and full-spectrum corrosion resistance, outperforming duplex and austenitic stainless steel in harsh high-temperature & chloride media. Solid shaft blanks eliminate complex forging pre-processing, directly machined into pump shafts, valve stems, subsea rotating spindles, aerospace turbine shafts and nuclear equipment transmission shafts for aerospace, offshore oil & gas, nuclear power, chemical and desalination industries.

Material Grade Characteristics – Inconel 625 (UNS N06625 / 2.4856)
  • Ni-Cr-Mo-Nb single-phase solid-solution alloy, strength obtained without precipitation aging
  • High molybdenum & niobium content greatly improves pitting resistance in brine and sour gas
  • Dense chromium oxide film maintains oxidation resistance under long-term high-temperature circulation
  • Retains full ductility and impact toughness at ultra-low cryogenic temperatures
  • No intergranular sensitization after welding; no mandatory post-weld heat treatment required
  • Good hot rolling, cold drawing and CNC machinability for all kinds of rotary shaft parts

Key Advantages
  1. 1 Solid-Solution High Strength Without Aging

    Mo-Nb elements deliver inherent high strength after solution annealing, skip extra aging heat treatment, simplify shaft processing workflow.

  2. 2 NACE Compliant Sour Gas Resistance

    Excellent sulfide stress cracking resistance, safe for subsea and H₂S-containing oil & gas rotating shafts.

  3. 3 Ultra-Wide Temperature Stability

    Maintain consistent strength, toughness & anti-oxidation performance from cryogenic to high-temperature furnace service.

  4. 4 Full-Spectrum Corrosion Protection

    Resist seawater, brine, mixed mineral acids & hot alkali, replace multiple stainless steel grades in one material.

  5. 5 Stable Welded Metallurgy

    No harmful carbide segregation during welding; welded shaft assemblies retain full corrosion resistance.

Typical Applications
  • Aerospace jet engine turbine shafts, exhaust rotating spindle blanks
  • Offshore subsea pump shafts, wellhead valve stems & rotary sealing spindles
  • Sour oil & gas downhole transmission shafts, high-pressure valve rods
  • Nuclear power reactor control shafts, heat exchanger rotating components
  • Chemical high-temperature reactor agitator shafts, acid pump spindles
  • Seawater desalination circulating pump main shafts
  • Industrial high-temperature furnace roller shafts
