Raw Material Specifications
Heat Treatment
Solution treated; wire is also cold finishedB805 stock is solution treated and rapidly cooled, with wire then cold finished; subsequent aging develops the strength required by the ordered final condition.
What we can make in Alloy 925
Full-length bar
Use for repeated turning of shafts, studs and valve components from one heat-traceable stock length. Bar diameter must include machining allowance for the finished surface and straightness.
Cut blank
Use saw-cut blanks for short-run machining or forging starts. Cutting allowance and end squareness affect how much usable length remains after facing.

Supply & preparation
Cut lengths preserve the heat identity of the original bar. Turning or grinding allowance follows the required finished diameter.
Material condition
Solution treatment and the specified aging condition are recorded against the production lot; final dimensions are checked after thermal processing.
Finished geometry
Diameter, straightness, surface condition and cut length are checked against the stock order.
Where 925 fits — and what matters
Offshore & Marine
Marine pump shafts and linkage pinsIncoloy 925 round bar provides machining stock for marine pump shafts and linkage pins, including turned shoulders, bearing seats and threaded ends. Bar diameter includes the allowance for finishing the final part. The assembled contact is exposed to saltwater, deposits and neighbouring metals.
Water Treatment & Desalination
Treatment-pump shafts and actuator partsIncoloy 925 round bar provides machining stock for treatment-pump shafts and actuator parts, including turned shoulders, bearing seats and threaded ends. Bar diameter includes the allowance for finishing the final part. The water stream, cleaning cycle and retained liquid define exposure at the installed part.
Oil & Gas
Valve actuator shafts and linkage pinsIncoloy 925 round bar provides machining stock for valve actuator shafts and linkage pins, including turned shoulders, bearing seats and threaded ends. Bar diameter includes the allowance for finishing the final part. Utility connections and pressure-boundary parts have separate acceptance requirements on the equipment drawing.
Same round bar. Different material priorities.
Incoloy 925 material dataInconel 625
Solid-solution strength and resistance to aggressive process liquids.
- Connection priority
- The mechanical requirement of the machined section
- Annealed or solution-annealed 625
- The delivery condition affects strength and high-temperature response. Keep the specified condition with the component’s mechanical acceptance; 718-style aging is not the strengthening route for 625. Include liquid retained at the machined diameter and cut surfaces of the future part in the exposure description.
Super Duplex 2507
Super-duplex strength and resistance to chloride pitting.
- Connection priority
- The mechanical requirement of the machined section
- Final duplex structure
- S32750 chemistry and final solution treatment belong together. Forming, section size and cooling affect the structure represented by the mechanical and corrosion records. Include liquid retained at the machined diameter and cut surfaces of the future part in the exposure description.
Monel K-500
Age-hardened strength in the nickel–copper alloy family.
- Connection priority
- The mechanical requirement of the machined section
- Strength and hydrogen exposure
- K-500 gains strength through aging. Cathodic protection, hydrogen exposure and the ordered condition need joint consideration in highly loaded marine components. Include liquid retained at the machined diameter and cut surfaces of the future part in the exposure description.

Questions about 925 round bar
Is the bar condition the same as the finished-part condition?
Not necessarily. A solution-treated or annealed blank may be selected for machining before a specified final treatment. Stock and finished-part mechanical records need to identify the conditions they represent.
