Quenching and tempering are processes that strengthen materials like steel and other iron-based alloys. These processes strengthen the alloys through heating the material while simultaneously cooling in water, oil, forced air, or gases such as nitrogen.See all results for this questionsp.info How to choose the best quenched tool steel?To prevent steam bubbles forming soft spots, a water quenching bath should be agitated. Fully hardened and tempered steels develop the best combination of strength and notch-ductility. The martensite of quenched tool steel is exceedingly brittle and highly stressed.See all results for this questionsp.info How does heat treatment cause quench cracking?Here are seven ways that steel can fail as a result of quench cracking from heat treatment. Overheating during the austenitizing portion of the heat treatment cycle can coarsen normally fine-grained steels. Coarse-grained steels increase hardening depth and are more prone to quench cracking than fine-grained steels.See all results for this question
Due to the quenching and self-tempering production process, rebars produced are also called ‘quenched and self-tempered (QST) rebars’.
