Complete Workflow for Measuring Depth of Decarburization of Steel Parts
A complete workflow for measuring decarburization depth of steel parts: perpendicular sampling, edge-protected mounting, grinding and polishing, followed by two routes — the metallographic method (measuring complete and partial decarburization after 4% nital etching) and the microhardness method (judged by hardness profile recovery) — per GB/T 224, with an applicability comparison table.
