Portable testing for massive titanium ingots at intake?
Hey everyone! I’m looking for some insights on testing the hardness of massive titanium billets right after they arrive at our facility. We usually cut samples for the lab, but it's really slowing down the intake process. I know titanium can be tricky, but since these are huge, solid blocks, I figured a portable rebound device might do the job. Does anyone have experience using handheld units on heavy Grade 5 titanium ingots? I’m worried about getting inconsistent readings across such large surface areas. Any advice on which specific method handles these massive alloys best without dragging them to a stationary machine?

For massive billets, you are definitely on the right track with the rebound method. Because the parts are so heavy, they won't vibrate and mess up the impact energy reading, which is the main issue with portable units. You just need a solid Leeb tester that has the right impact body (usually a type D or G for rougher surfaces) and proper conversion tables for titanium. I use gear from https://teqto.pro/portable-hardness-testers/leeb-hardness-testers for our heavy intake inspections. They handle large solid blocks perfectly and the interface is quick enough that you can spot-check a whole batch of ingots before they even hit the warehouse floor.
