The 4 Types of Heat Treatment Steel Undergoes
Tempering consists of the same three stages as heat treatment. The main difference is the temperature of tempering and its effect on hardness, strength, and, of course, ductility. When you temper a steel part, you reduce the hardness that was caused by hardening and you develop certain physical properties. Tempering always follows …
