Stainless Steel Thickness Measurement

Stainless steel is widely used in the food, pharmaceutical and chemical industries and in process plants for its corrosion resistance. Ultrasonic thickness measurement on stainless steels is generally reliable, but it requires specific care on coarse-grained austenitic materials (welds) and duplex alloys, where attenuation and scattering of the signal may call for lower-frequency probes.

This section gathers guides and application cases for ultrasonic measurement on stainless steel, with comparisons between material families (304/316 austenitic, AISI 430 ferritic, duplex 2205).
Dakota instruments for stainless steel

Dakota CMX Series — corrosion gauges with visual A-Scan to discriminate echoes on coarse-grained material.
Dakota PMX2-DL / PMX3-DL — precision gauges for high-accuracy measurements.
Dakota PMX4-DL — high-penetration gauge for attenuating alloys.
