Throughout the literature I have found published values for 304SS to be 5640m/s to 5888m/s. In general, 304 SS might be considered to have a lower velocity than most carbon steels. Variations in some of the constituents of 304SS can vary by over 1% and then there is also the rolling condition of your samples,
#Speed of sound in steel iso
The "official" velocity for the ISO Calibration block 1 (the IIW block) is 5920m/s +/-30m/s so your version of carbon steel is already at the lower end of the range assumed for the IIW block used for calibrations.
We did a study in a single alloy of steel from different mills and found the compression velocity varied from 5802m/s to 6073m/s and the velocity also varied with the direction measured (anisotropic). What is the Sound Barrier When airplanes go faster than the speed of sound (also called Mach 1), its called breaking the sound barrier. Sound travels 4 times faster in water (1,482 meters per second) and around 13 times faster through steel (4,512 meters per second). Variations can occur due to alloy, heat treatment and rolling processes. At this rate sound will travel one mile in around five seconds. Mark, acoustic velocities are not absolutes.
Re: sound speed on 304 stainless steel In Reply to Mark at 00:12 Mar-30-2016 (Opening). A material such as steel will experience a very small deformation of shape (and dimension) when a stress is applied to it. R & D, Materials Research Institute, Canada, Joined Nov 1998, It travels 4 times faster in water (1,482 metres per second) and 13 times faster through steel (4,512 metres per second). For instance if the thunder is heard 3 seconds after the lightning is seen, then sound (whose speed is approximated as 345 m/s) has traveled a distance of distance v t 345 m/s 3 s 1035 m If this value is converted to miles (divide by 1600 m/1 mi), then the storm is a distance of 0.65 miles away.
