Heat Treatment Services
Improve the physical and mechanical properties of materials through heat treatment. Improve hardness, increase strength, enhance toughness, stress relief, and more.
introduction
Harden with Heat Treatment
Enhancing hardness makes materials more resistant to wear and abrasion. Make them less prone to fracture or failure under impact or shock loading.
DEK's approach involves a systematic sequence of steps, beginning with thoroughly analyzing raw materials to determine the most suitable heat treatment methods. Then, finalizing with rigorous testing, such as hardness assessments, to verify that the heat treatment adheres to specified requirements, with a stringent focus on quality control to ensure consistent and reliable final products. Heat treatment processes like annealing can induce recrystallization, leading to a more uniform and refined microstructure, improving overall material properties. DEK can precisely control heat treatment processes to achieve desired outcomes. This level of control allows for the customization of material properties based on specific engineering requirements.
TECHNOLOGY OVERVIEW
More About Heat Treatment
What’s Heat Treatment?
Heat treatment is a process that modifies materials' physical, mechanical, and sometimes chemical characteristics, especially metals or alloys. The method involves controlled heating and cooling to enhance properties like hardness, strength, toughness, and ductility. Annealing involves slow cooling to relieve internal stresses and improve ductility while quenching rapidly cools to increase hardness. Tempering balances hardness and toughness by reheating and controlled cooling. Normalizing enhances grain structure and properties, and hardening increases hardness through rapid cooling. These processes are important in manufacturing tools, automotive parts, gears, and other products, allowing materials to be customized for specific applications.

FAQ
Heat Treatment FAQ
There are five main ways to improve metal properties through heat treatment: Annealing (slow cooling to relieve stress), Normalizing (uniform cooling for consistent microstructure), Quenching (rapid cooling for hardness), Tempering (reducing brittleness), and Case Hardening (adding elements for a hardened surface).
Heat treatment involves heating metal to change its structure and then controlled cooling. The first stage, heating, initiates structural changes, while the second stage, cooling, determines the final properties like hardness and toughness.
Annealing is a widely used heat treatment. It involves heating metal to a specific temperature and then slowly cooling it. This process relieves stress, refines the grain structure, and improves machinability.
Heat treatment is highly effective for enhancing material properties. It can significantly increase hardness, strength, and durability by carefully controlling temperature and cooling rates.
Heat treatment failures include decarburization (loss of carbon during heating), quench cracking (undesirable fractures due to rapid cooling), distortion (changes in shape), overheating, and incomplete transformation (failure to achieve desired properties).
