- Raw material problem?
- Poor spring making?
- Design error?
- Abuse in service?
We can answer all these questions!
|
| Fatigue failure is more likely than any other mechanism, but was it caused by: |
|
|
- Defect in the wire?
- Scratch from coiling?
- Substandard shot peening?
- Corrosion in service?
- Operating stresses too high?
We can answer all these questions!
|
| Hydrogen embrittlement can be diagnosed, but was it caused by: |
|
|
- Poor cleaning practise
- Electroplating inappropriate steel?
- De-embrittlement incorrectly applied?
- Corrosion in service?
We can answer all these questions!

Investigations are supervised by highly experienced technical staff with a specialist knowledge of materials and applications. The laboratory has examined failed springs from all over the world. IST reports include a diagnosis of the cause of failure and offer expert advice on how to reduce the risk of further failures.
This confidential service includes the following features:
Diagnosis
- Establish the cause of failure:
- Defective raw material.
- Inappropriate design.
- Manufacturing defects.
- Unforeseen service or environmental effects.
- Abuse in service.
Techniques
- Photography of relevant features may be viewed on-line by clients.
- Optical metallography to identify structure and surface quality.
- Examination of operating stresses.
- Raw material chemical analysis and mechanical testing.
- Scanning electron microscopy to identify fracture mechanisms.
- Residual stress determination.
- EDX analysis
| Those techniques likely to pinpoint the cause of failure are selected upon receipt of samples and a competitively priced, no obligation quotation is immediately supplied. Within 5 days (2 if our priority service is requested) a failure diagnosis will be discussed with the customer by telephone / fax or E-mail. A detailed report, including certification and photographic evidence is mailed and / or e-mailed on completion. |
