Hydrochloric Acid Pickling Vs Shot Blasting
Dec 19, 2008 March 5, 2013. A. Hi Dharmik. You have given us no context, like whether you are also speaking of steel mill operations or of plating small parts, but I dont know offhand anything that would preclude shot blasting instead of pickling. If you are speaking of hardened steel, blasting offers the advantage of no hydrogen embrittlement.

Sand Dunes Coastal Care
The beach is the sole source of sand for coastal dunes, and every single sand grain in a dune has come across the beach at some time in its history. In fact, each grain probably has made the trip many times (Fig. 3.1) because when the wind reverses and blows offshore some of the grains go right back to the beach.
