Why Heat Treatment?

By subjecting metals or alloys to controlled heating and cooling cycles, the microstructure of the material is altered, resulting in improvements in hardness, strength, toughness, and ductility. This process also helps to relieve internal stresses, reducing the risk of distortion or failure in the finished components. Heat treatment in manufacturing is a critical process to enhance the mechanical properties of materials. 

Let’s delve into the diverse applications of heat treatment, showcasing its vital role in shaping industries across various sectors. Join us as we navigate through eight practical examples, each illustrating how heat treatment revolutionizes manufacturing processes.
