Quench cracking causes traced to the 300°C cooling rate, not just maximum rate. Check whether your quenchant concentration or oil condition pushed it too high.

How to diagnose soft spots after quenching: trace vapor blanket retention, agitation coverage, PAG concentration and water in quench oil—then confirm with a cooling curve.

GM Quenchometer and cooling curve analysis answer different questions. See what ASTM D3520 measures, what it misses, and where the KHR-A Quenchometer fits.

IVF Quenchtest vs. IVF SmartQuench vs. KHR-A quenchometer: how software depth and on-site access shape the right choice for quenching media in heat treatment.
