The tests that matter, and what each one finds
Hardness and density verify the grade. Ultrasonic and penetrant inspection find internal and surface defects. Together they cover the failure modes that reach the field.
Hardness, density and porosity
These three measurements verify that the grade you received is the grade you ordered and that the sintering cycle worked. They are cheap, fast and sensitive to the most common process failures, which is why they belong in every specification.

Non-destructive inspection
Ultrasonic testing finds internal voids and bond defects; dye penetrant finds surface-breaking cracks; eddy-current methods sort material and near-surface conditions. Each costs money, and each is justified where the consequence of a missed defect is high.
Traceability is what makes a claim answerable
Powder lot, pressing batch, sintering cycle and inspection results, linked to the part’s identification. Without that link, a field failure cannot be investigated.
Batch records and identification
A part that can be traced to its powder lot and its process cycle can be investigated when it fails. A part that cannot be traced turns every failure into an argument. Marking and record-keeping are the cheapest quality investment a factory makes.

Auditing a supplier
Ask for the inspection method, a sample record and an example of a batch investigation. Equipment lists are easy to produce; a completed investigation with conclusions is not, and it is the clearest sign of a working quality system.

Quality and testing questions
What should a goods-in inspection cover?
Dimensions against the drawing, hardness and density where the specification calls for them, and a visual check on the bond line and any coating. That catches the majority of supplier errors before the parts reach a machine.
Is ultrasonic testing worth the cost?
Where a missed internal defect has safety or contract consequences, yes. For lower-duty applications the same money is usually better spent on a rigorous dimensional and hardness check.
What is batch traceability for?
Investigating failures and containing defects. If a problem is found in one batch, traceability is what allows a supplier to identify every affected part rather than recalling everything.
How do I audit a carbide supplier?
Ask for inspection methods, an example batch record and a completed failure investigation. Records show what actually happened; equipment lists only show what could happen.
Can I specify inspection in a purchase order?
Yes, and you should. Naming the method and the acceptance criteria converts quality from an expectation into an enforceable requirement.
