DESTRUCTIVE TESTING

Destructive Testing (DT) is a method of testing used in metallurgy that involves testing a material to the point of failure to understand its physical properties. The main goal of this type of testing is to identify the material’s performance characteristics under various levels of stress and strain.
We offer Chemical Testing, Mechanical Testing, Metallurgy Testing and Corrosion Testing services.

METALLOGRAPHIC TESTING

Metallographic testing, or metallography, involves studying the physical structure and components of metals through microscopy. This testing examines specimens to reveal features such as grain size, phase distribution, and inclusions, which can indicate a metal's hardness, flexibility, and strength. It is crucial for understanding a metal’s performance, diagnosing failures, and ensuring adherence to required standards.
