WCC Pump Shaft Sleeve
ASTM A216 WCC / UNS J02503. 0.07–3.72 kg across 7 catalogued sizes.
The Pump Shaft Sleeve is supplied as an investment casting in WCC (ASTM A216 WCC / UNS J02503). In this grade the 7 catalogued sizes weigh 0.07 to 3.72 kg as cast, before machining allowance. Higher strength than WCB at the same weldability, for larger pressure castings.

Why WCC for a pump shaft sleeve
- Pressure boundary
- This part retains pressure, so the grade has to hold its rating at temperature and pass a hydrostatic shell test at 1.5 times that rating. Approx. -29 C to +425 C.
- Rotating duty
- The part is balanced after the bore and hub face are machined, because those are the datums the balance is measured against. Grade choice affects this through density: a change of alloy changes the mass and therefore the residual unbalance for the same geometry.
- Wear
- Abrasion or erosion sets the service life here, and hardness after heat treatment matters more than tensile strength. Machinability is the trade: good.
- Fabrication
- Machinability: good. Weldability: excellent. Both change the finished cost as much as the metal price does, and neither shows up on a materials comparison table.
Casting Weight in WCC
As-cast weight per size, before machining allowance, scaled from the alloy density. Gates and risers are additional and are not part of the finished-part weight.

Alternatives to WCC for This Part
The question is rarely "tell me about this grade" — it is "this grade, or something else?". These are the other grades this part is legitimately cast in.
| Grade | Specification | Corrosion | Temperature |
|---|---|---|---|
| CA6NM | ASTM A743 CA6NM / UNS J91540 | Moderate — better than carbon steel in water, well short of CF8M in chlorides. | approx. -73 C to +370 C |
| CF8M | ASTM A351 CF8M / UNS J92900 (cast 316) | Good pitting and crevice resistance in chlorides; standard choice for seawater-adjacent and chemical process duty. | approx. -196 C to +550 C, derated for pressure-retaining service above 425 C |
| CF3M | ASTM A351 CF3M / UNS J92800 (cast 316L) | As CF8M, with the low carbon that prevents sensitization at welds. | approx. -196 C to +425 C |

Frequently Asked Questions
Is WCC the right grade for a pump shaft sleeve?
Higher strength than WCB at the same weldability, for larger pressure castings. None inherent; requires a protective coating. Approx. -29 C to +425 C.
What does a pump shaft sleeve weigh in WCC?
Between 0.07 kg and 3.72 kg as cast across the 7 catalogued sizes, before machining allowance. The figure scales with the alloy density, so the same geometry in a different grade weighs proportionally more or less — which is why the weight is stated per grade rather than once for the part.
Can a pump shaft sleeve in WCC be welded or machined?
Machinability: good. Weldability: excellent. Both affect the finished cost as much as the metal price does, so state the machining scope on the RFQ rather than leaving it to be discovered.
How do I request a quotation?
Configure the drawing on this page — size, alloy, finish — and submit the form. Attaching a drawing or a STEP file is the fastest route to a firm price, and it lets us flag a castability issue before you commit to tooling.
More on the Pump Shaft Sleeve
The full record for the pump shaft sleeve — every catalogued size, the parametric drawing and the quote form — is on the Pump Shaft Sleeve product page.
Each grade changes the price, the weight and what the part survives, so there is a page per grade for this part: CA6NM (the catalog grade), WCB (the carbon-steel cost baseline), CF8M (the chloride-resistant default), CF3M (low carbon, for welded assemblies), CF8 (cheaper, where chlorides are absent) and CA15 (hardenable, for wear-loaded duty).
How it is shelled decides the tolerance and the surface you get, and the tolerance band is worked out against this part's own dimensions on each: Silica Sol Casting (DCTG 5 – 7, Ra 3.2 – 6.3 µm), Water Glass Casting (DCTG 7 – 9, Ra 6.3 – 12.5 µm) and Composite Shell Casting (DCTG 6 – 8, Ra 6.3 – 12.5 µm).
The specification and the testing change by sector more than the geometry does, so the pump shaft sleeve is written up separately for Pumps & Fluid Handling, Chemical Processing, Water & Wastewater, Marine & Offshore and Mining & Minerals.
If the question is still whether a casting is the right way to make this part at all, the Pump Shaft Sleeve application guide covers where it is used, what has to be decided before a price exists, and where investment casting is the wrong answer.
