Hardness Testing
Verify hardness — sample by sample, batch by batch or in-line.
The inspection problem
Hardness is often the last check before parts move to the next step. It has to be right on the first sample, and consistent through the batch.
Why it matters
Hardness deviations catch heat-treatment escapes, wrong material and process drift before they leave the plant.
Which method fits your part?
Every method has a sweet spot and a limitation. Choose based on defect, geometry, throughput and access — not on habit.
Rockwell / Brinell / Vickers / Knoop
When it fits: Standard methods depending on part, material and load range.
Limitations: Load and surface-preparation requirements differ per method.
Portable hardness testing
When it fits: Large or immovable parts.
Limitations: Lower precision than bench testers; correlation curves needed.
Automated production hardness testing
When it fits: 100% inspection on production lines.
Limitations: Requires part-specific fixturing.
