   What about the backside of the piece you're blasting?

   Temperature is not the reason for sheetmetal warping. I can demonstrate this in my vaporblaster where I can bend sheetmetal and the temp is barely 50 degrees but when you „hammer“ sheetmetal from above you stretch the surface on one side and it bends. Now if you „hammer“ the backside you can straighten it again to some extend. Now „shooting“ at a shallow angle only „scratches“ the surface but does not stretch it and that avoids bending.

   Proper selection of abrasive and pressure is important consideration as well as variations in material thickness and types.
