Austenitic Stainless Steel Solution DAAH – Dual Linear Array Probe
300 series stainless steels are the most common sub-group of austenitic steels and are used in a large variety of processes and industries, typically for corrosion resistance of high temperature service. Comprehensive inspection techniques are vital to ensure safe operation.
The amount and ratio of chromium and silicone in stainless steel can cause signal attenuation and noise, making inspection a challenging task. The conventional ultrasonic approach has limitations, while the combination of linear array, focusing and beam-forming provide improved and broader inspection capabilities.
The new DAAH (detachable active array head) coupled with DLA (dual linear array) solution from Sonatest are specifically designed and developed for such application challenges.
