Austenitic Stainless Steel Solution DAAH - Dual Linear Array Probe

Austenitic stainless steel is well known for its high mechanical properties and corrosion resistance.


This material is often used in the oil and gas, and nuclear industries where ultrasonic inspection techniques represent an important portion of the quality control process. However, these alloys often are very attenuating and the sound propagation in this material is anisotropic.

Mainly caused by the grain size and orientation, especially inside the welded volume of a component, the localisation, the characterisation and the sizing of potential defects are complicated, hence lowering theprobability of detection.
