What is the method?
Portable Hardness Testing uses handheld instruments to determine material hardness on site using methods such as Leeb rebound, UCI, or portable indentation techniques.
Application
Portable Hardness Testing uses handheld instruments to determine material hardness on site using methods such as Leeb rebound, UCI, or portable indentation techniques.
Key Benefits
- Rapid field measurement of hardness.
- Reduces need for sample removal and laboratory testing.
- Useful for fabrication, repair, and maintenance verification.
- Portable and practical for plant and workshop use.
Inspection Capabilities
- Provides direct on-site indication of material hardness and local mechanical condition.
- Particularly useful for verifying heat treatment effectiveness, HAZ hardness, and post-repair metallurgical condition.
- Can support investigations involving brittleness, over-hardening, under-hardening, or improper PWHT.
- Offers quick field-based mechanical property verification where destructive testing is not practical.
Limitations
- Influenced by surface finish, geometry, thickness, and microstructure.
- Not all methods are suitable for all materials or sections.
- Hardness scale conversions may introduce uncertainty.
- Critical results may require validation against standards or laboratory methods.
