    Quenching and tempering steel Quenching and tempering consists of a two stage heat treatment process. Stage one includes hardening, in which the steel is austenitized to approximately 900°C and then quickly cooled with water or oil. Stage two consists of tempering the material to obtain the desired material properties.Read More

  • Difference Between Quenching and Tempering Compare

    Jul 19, 2019 · Quenching is the process of rapid cooling after heat treatment of a workpiece, while tempering is a process that involves heat treating to increase the toughness of iron based alloys. So, the key difference between quenching and tempering is that quenching is the rapid cooling of a workpiece, whereas tempering is heat treating a workpiece.Read More

Be sure to have the blow torch pointed away from your body as shown. Make sure no one else is within t3. Place the curved part of the rod (the U) in the hottest part of the flame by holding the two ends of the steel rod. The hottest part of the fl4. When the rod becomes a deep orange in color, take the rod out of the flame and quickly dip it into the water inside the bucket, as shown in the5. Repeat steps 3 and 4 with the second steel rod.6. Take the second steel rod and temper it by reheating it with the torch for about 10 seconds. Do not temper the first steel rod! Quench again by7. Attempt to straighten both rods to illustrate the difference in mechanical properties. The first rod (the rod that was not tempered, top photo),
