Which thermal runaway risk increases significantly when coolant flow fails during precision grinding of hardened steel?

💡 Explanation

Tempering induced softening is more likely post-grinding because inadequate coolant causes elevated temperatures, creating metallurgical phase changes via thermal activation as the mechanism, therefore, the surface softens, rather than retaining hardness.
