www.stal.com.cnsteels. Oil quenching these alloys from temperatures between 1800°F to 1950°F (982-1066°C) produces the highest strength and/or wear resistance as well as corrosion resistance. A range of as-quenched hardnesses is achieved in these alloys by varying the
Stress Relief - Heat Treat Doctor.com
www.heat-treat-doctor.comFor many alloy steels, little or no stress relief occurs at temperatures less than approximately 500°F (260°C), while approximately 90% of the stress is relieved by 1000°F (540°C). The maximum temperature for stress relief is limited to 55°F (30°C) below the tempering temperature used after quenching from the hardening process.

This structure contains inherent stresses that can easily cause crack-ing. But this can be prevented by reheating the steel to a certain tem-perature, reducing the stresses and transforming the retained austenite
