Heat Treating
Heat treating is a group of industrial and metalworking processes used to modify the physical properties of a material – often steel – to increase its resistance to wear, strength, and ductility. Heat treating is a process often used in manufacturing, and is essential in the production of parts and components used in a wide range of applications. Heat treating can involve several steps, including the use of high temperatures, rapid cooling, and controlled atmospheric conditions. Heat treating is a specialized form of metalworking that essentially uses energy in the form of heat to change the microstructure of metals and alloys, which in turn modifies their physical and chemical properties. Various types of heat treatment can improve the ductility, strength, wear resistance, and other properties of the material.
The application of heat treatment can range from relatively simple operations such as annealing to more complex techniques such as cryogenic processing. What heat treat shop you choose will depend on the type of metal and its desired end application, as well as the types of processes the shop is capable of performing. When a metal is heat treated, it is essentially heated and then cooled in a controlled manner, usually in a piece of specialized equipment known as a heat treat furnace. The process alters the microstructure of the metal, which can alter its physical and mechanical properties. Common heat treatable metals include aluminum, titanium, stainless steel, and tool steel.
Heat treating offers a wide range of benefits, including improved surface hardness, wear resistance, and ductility. Hardening increases the strength and abrasion resistance of metals, while tempering increases ductility and toughness and makes metals less brittle. Heat treatments can also be used to reduce stress in parts that have been machined, welded, or exposed to other extreme temperatures. The objective of heat treating is to modify the physical properties of a material based on its intended application, allowing for better performance and longevity.
