Velocity of stainless steel 316 and plexiglass

Please,

could anyone provide me with the ultrasound velocity of the following materials:
steel 316
plexiglass
perspex (lucite)

I really cannot find accurate values.

Thank you in advance.

.Here is some info. for you
Lucite Vlong 2680m/sec Vshear 1050m/sec
Plexiglass a)UVA Vlong 2760m/sec Vshear 1090m/sec
b)UVAII Vlong 2730m/sec Vshear 1080m/sec
Hope this helps
Regards

The ultrasound velocity in stainless steel is strongly depending on the material (cast, forged, weld), especially on the grain size and the grain orientation, leading to anisotropy.
In general, the velocity is lower than in heat treated, forged, fine grain ferritic carbon steel (clong = 5920 m/s, ctrans =3250 m/s).
So, clong = 5800 m/s might be a suitable average value, but sometimes it can be also down to 5400 m/s.
You have to use suitable control specimens or you have calibrate on the test specimen directly.

Keep it simple. If you have a known thickness of a material, you can determine it's exact velocity. Measure a sample with a micrometer. Set your screen range on your A-scan to twice that thickness. After compensating for probe delay, adjust your velocity so you have one signal at 50% and one at 100%.

Easy, right?

...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
