The microstructure of cast stainless steel can vary considerably, from elastically isotropic with an equiaxial, relatively small grain structure to elastically anisotropic with a columnar grain structure to a combination of the two. The ultrasonic
97259 EFFECT OF TEMPERATURE ON ULTRASONIC To identify the effect of temperature on straight beam (0°)ultrasonic thickness values (i.e., changes in the sound velocity), experiments were conducted using carbon steel, two low-alloy steels, and 316 stainless steel materials at temperatures ranging from 70°F to 650°F (21°C to 343°C).
IntroductionDevelopments to DateRecommended Ultrasonic Inspection StrategyPossibilities For Reducing Grain SizesSummaryReferencesCladding, dissimilar metal welds, austenitics all present similar ultrasonic inspection problems due to beam steering, splitting, refraction and absorption. Most of the published ultrasonic inspection work has been performed within the nuclear industry, as expected. Nuclear was the first industry to establish the source of problems from cast stainless steel pipes (specifically, large, oriented grains), and the first to model and analyze it. In general, they have shown that 1. Shorter ultrason:ultrasonic thickness gauge:Industrial DecentGadget Ultrasonic Thickness Meter Tester Gauge Velocity 1.2~225mm Metal Wave. 4.1 out of 5 stars34.

Sound Speeds in Water, Liquid and Materials - RS HydroSound Speed (or sound velocity) refers to the speed of sound waves passing through an elastic medium. The actual speed depends upon the medium (for example, sound waves move faster through water than through air - because water has a higher density). 302 Stainless Steel:3,120:10,236:303 Stainless Steel:3,120:10,236:304 Stainless Steel
Ultrasonic and structural characterization of anisotropic Jun 01, 2010 · The reference mock-up in wrought austenitic stainless steel will be described by an isotropic domain whose ultrasonic velocities are 5740 and 3080 m/s, respectively, for longitudinal and transverse waves.
Cast stainless steel (CSS), used extensively for nuclear power plant components, has a range of complex grain structures that makes conventional ultrasonic examination difficult. The high attenuation and scattering caused by coarse grains hamper defect detection, and wave velocity variations and beam skewing caused by highly ordered grains also
Ultrasonic velocity measurements for characterizing the Ultrasonic velocity measurements have been used to characterize the microstructural evolution during annealing of cold worked titanium modified 316 stainless steel. Velocity measurements with an
VX Ultrasonic Velocity Gauge - Sound SolutionsWith the hand-held VX Ultrasonic Velocity gauge, you can determine material velocities by measuring a known thickness, entering a known thickness into the VX, and the material velocity will be displayed. The tools backlit display is easy to read, even in dim light, and the unit operates for up to 200 hours on a single set of batteries.
The Ultrasonic Thickness Gauges (UTG) / Material Thickness Gauges (MTG) can be programmed by the user to the appropriate Material in two ways :. Using known standards of the same material set the calibration to the thickness; Using the Frequency calibration, set the frequency to the appropriate Material using the Velocity / Speed of Sound Chart below.ANALYTICAL ULTRASONICS FOR STRUCTURAL MATERIALSsound velocity in the straight (wrought) section between the two elbows was found to be 5760 m/s, a value consistent with previous measurements on stainless steel. Attempts were also made to propagate I-MHz, 45° longitudinal waves in the cast material with two transducers in a pitch-catch mode. No backwall echo was detected
