                        Metal Heat Treatment Processes

                        2024-05-31

                        There are several types of heat treatment processes:


                        Differential Hardening

                        Differential hardening is a heat treatment process that involves heating and cooling two or more areas on a metal workpiece at different rates.

                        Annealing
                        Annealing is a heat treatment process in which a metal workpiece is heated and then slowly cooled to trigger the formation of micro-sized crystals and, therefore, increase its strength and hardness. When performed on either ferrous or nonferrous metals, annealing creates pearlite, which of course is particularly strong. Pearlite can only be created by cooling iron or iron alloy metals, typically at a slow rate.

                        Stress Reduction
                        Also known as stress relieving, stress reduction is a heat treatment process that’s designed to reduce stresses within a metal workpiece.

                        Normalizing
                        Normalizing is a heat treatment process that lives up to its namesake by evenly distributing or “normalizing” the composition of a metal workpiece. It typically involves heating a metal workpiece up to a specific temperature, after which the workpiece is air-cooled. Like annealing, normalizing produces pearlite, though it’s also capable of producing other metal microstructures like martensite and bainite.

                        Decarburization

                        Finally, decarburization is a heat treatment process that’s designed to lower the carbon content of steel. If a steel workpiece has too much carbon, it may be too soft for its intended application. Therefore, manufacturing companies often perform decarburization to lower the carbon content of their steel workpieces.



                        ABOUT  KEVA
                        Keva Casting is a professional casting company that focuses on Construction, Machinery, Automobile, Hardware, Pipeline and many other industries.
                        We provide top quality products with the best service based on our complete production chain including our own mold design, advanced production techniques, and full management of the supply chain. Keva Casting has two factories located in Zhucheng, China's Shandong province.
                        We use "shell molding", which is a new technique that has been developed in recent years.This new technique has simplified production procedures and reduced air pollution compared with traditional sand casting and investment casting. Shell making and core making are faster to ensure production in enormous quantities. The dimensions and surface finishing are satisfactory for all kinds of industrial requirements. Besides supplying our own formwork & scaffolding systems, our casting products also supply OEM services in various industries.
