Full Annealing of Steel and Aluminum: An Insightful Overview
Welcome to our comprehensive guide on the full annealing process for steel and aluminum parts. Full annealing, a principal heat-treatment procedure, significantly enhances the mechanical and structural attributes of metal workpieces. Dive deep into its technical advantages and the capabilities we offer.
Steel Products
Process:
Full annealing of steel is executed by raising the parts above the critical eutectoid temperature, between 1475°F to 1650°F, depending on the cross section size. The parts are held at this temperature for an appropriate duration and then slow-cooled, fostering a uniform microstructure primarily of ferrite and coarse pearlite. This strategic process yields a product characterized by maximum ductility, uniformity, and enhanced machinability.
Capability:
At ThermTech, we conduct full annealing treatments in batch-type furnaces, ensuring optimal process and lot control. Meeting the rigorous standards of AMS 2750, our furnaces maintain temperature uniformity and accuracy. Our most expansive furnace, dedicated to the full anneal procedure, measures 72” x 36” x 144”. For annealing tool steels or intricate alloys, our vacuum furnaces come into play, eliminating the risk of material surface decarburization.
Aluminum
Process:
Full annealing for aluminum parts involves heating the components to a temperature marginally below that used for a solution treating process, approximately around 775°F, followed by cooling to room temperature. This precise methodology results in a product with elevated ductility and toughness, reduced hardness and strength, as well as superior machinability and consistent properties.
Recommendations:
We frequently advise this treatment for clients with aluminum products intended for shaping or forming processes, or those necessitating further hardening treatments. ThermTech boasts extensive expertise in annealing a selection of aluminum alloys, including:
