FAQ

What influence does the chemical composition of a certain steel group has on the UCI measurement?
For example, will the result be different on 100Cr6, 100CrMnSi6-4 or 100CrMnMoSi8-4-6 ? All the mentioned steel compositions have similar values of Elastic modulus (E), therefore the results will not be strongly affected by the UCI measurement. However, the ideal values are measured with 100CR6.

What is UCI particularly good for?
Inspection of HAZ (Heat Affected Zones) especially used in oil and gas in industry, inspection of lighter objects where Leeb can not be used due to weight limitation, inspection of areas that can not be reached by anything else than think nose of UCI.

What parameters are important when choosing the right UCI Probe?
There are several important parameters that shall be taken into account when selecting the UCI probe: Minimum thickness of the object If a coating is tested, then also the minimum thickness of the “coating“ which should correspond at least 10x the indentation depth by an indenter, Elastic modulus of the material is important to be known, as conventional UCI devices are calibrated to low alloy steel with E around 210 GPa Appropriate surface roughness, specific for the selected probe

What is the most used Load?
The HV5 (5kgf, 49.05 N) load is the most commonly used, especially within the Oil and Gas industry.
