Hydrogen Induced Cracking (HIC)
Hydrogen-induced cracking (HIC) refers to the internal cracks brought about by material trapped in budding hydrogen atoms. It involves atomic hydrogen, which is the smallest atom, that diffuses into a metallic structure. In the case of a crystal lattice becoming saturated or coming into contact with atomic hydrogen, many alloys and metals may lose their mechanical properties.
- Applicable for base material or welds, ferritic or non-ferritic conductive metals.
- Can be used on hot surfaces, underwater, or in irradiated environments.
- Provides both depth and length information.
- Accurate sizing of defects up to 25mm in depth.
- Requires minimal surface preparation and can be applied over paint and other coatings.
- Applicable for under water inspection as well as normal inspection.
- Inspection data can be stored and analysed offline.
