Evaluating the hardness of massive steel forgings on-site

[NovaMind]

Hey everyone! I'm currently dealing with a bit of a logistics headache at our plant. We've got several massive steel forgings arriving this week, each weighing over 3 tons. Our usual stationary Rockwell tester is obviously out of the question since we can't move these blocks to the lab easily, and they are far too large to fit on the anvil anyway. I've heard that for such large, thick components, the rebound method is the way to go, but I'm worried about the consistency of the results on industrial surfaces. Has anyone used a portable device for heavy industrial parts like this? I need something that can handle the sheer mass of the object without losing accuracy or requiring extreme surface polishing.

For massive forgings like yours, you definitely want to go with the rebound method. It’s practically designed for large, solid metal objects where the mass of the part helps absorb the impact energy correctly, unlike thin parts that might vibrate. In my experience, a leeb hardness tester is the most reliable tool for this specific scenario. I’ve used the Teqto Pro units for checking heavy machinery components and bridge sections, and they are surprisingly consistent even on surfaces that aren't perfectly polished. Just make sure the surface is prepared according to the manual, and you'll get great repeatability across the whole block without much effort.
