If you’re in the process of developing metal products, parts or components, it’s important to understand as much as possible about a variety of metal treatment processes, including annealing and quenching. If you’re unsure about some of the specifics of how these processes work or which applications they are most suitable for, it’s a good idea to get some more information. Keep reading to learn about metal quenching and the annealing process in Gastonia, NC.
What is quenching?
Metal quenching is a metal treatment process that’s designed to preserve the desirable properties of metal alloys and prevent structural changes during the cooling process. When metal is allowed to cool slowly, its properties can change dramatically. With quenching, heated metal is submerged in oil, water or brine to rapidly cool it down. Quenched metal tends to be much harder and more brittle than metal that’s allowed to cool down more gradually. To counteract this brittleness, metal is then treated using another process. Sometimes, metal is treated with an annealing process in Gastonia, NC after quenching.
What is annealing?
Annealing is a metal treatment process that uses heat to alter the characteristics of metal after quenching. The main purpose of annealing is to remove the hardness of metal alloys and increase ductility. After quenching, metal tends to become brittle, and that can increase the risk of breakage. Annealing balances the properties of metal alloys to maximize strength and durability for a variety of applications. Annealing removes residual stresses in the metal, improves machinability and makes the metal more formable.
During the annealing process in Gastonia, NC, the material that’s being annealed is raised to a temperature where the internal stresses of the metal are relieved. Next, the material is heated to a higher temperature that’s below its melting point to encourage the development of new grains without causing any new stress points to form. Finally, the metal is allowed to cool at a specified rate to allow grains to fully develop.
Quenching vs. annealing
A lot of people wonder about the difference between quenching and annealing. While these processes are very different in a number of ways, they work together to create metal products that are strong, durable, moldable and suitable for versatile applications. Quenching and annealing can be used for a variety of different metal alloys, including steel, cast iron, copper, aluminum and brass. The specific duration and protocol for these processes can vary widely depending on the type of metal that’s being treated and the intended application, so it’s important to work with a professional to ensure the best results for the part, product or component you’re working on.
