"Heat Treatment of Steels"





Designed to give your company a strong competitive edge in today's rapidly changing marketplace, the course focus is on translating complex principles and procedures into easy to understand terms that will enable participants to gain a valuable working understanding of the fundamental principles of heat treatment of steels.









Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape.

Heat treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming.

Heat Treatment is often associated with increasing the strength of material, but it can also be used to alter certain manufacturability objectives such as improve machining, improve formability, restore ductility after a cold working operation. Thus it is a very enabling manufacturing process that can not only help other manufacturing process, but can also improve product performance by increasing strength or other desirable characteristics.

Steels are particularly suitable for heat treatment, since they respond well to heat treatment and the commercial use of steels exceeds that of any other material. Steels are heat treated for one of the following reasons:

  • Softening
    Softening is done to reduce strength or hardness, remove residual stresses, improve toughnesss, restore ductility, refine grain size or change the electromagnetic properties of the steel.

    Restoring ductility or removing residual stresses is a necessary operation when a large amount of cold working is to be performed, such as in a cold-rolling operation or wiredrawing. Annealing - full Process, spheroidizing, normalizing and tempering - austempering, martempering are the principal ways by which steel is softened.


  • Hardening
    Hardening of steels is done to increase the strength and wear properties.One of the pre-requisites for hardening is sufficient carbon and alloy content.

    If there is sufficient Carbon content then the steel can be directly hardened. Otherwise the surface of the part has to be Carbon enriched using some diffusion treatment hardening techniques. 


  • Material modification common heat treatments
    Heat treatment is used to modify properties of materials in addition to hardening and softening.

    These processes modify the behavior of the steels in a beneficial manner to maximize service life, e.g., stress relieving, or strength properties, e.g., cryogenic treatment, or some other desirable properties, e.g., spring aging.



Practical training with significant benefits.   This interactive, highly practical course will be of significant benefit to the entire spectrum of personnel either directly or indirectly assoicated with heat treatment, including design and manufacturing engineers, plant managers, supervisors, and technicians.

Participants will gain a technical familiarization with heat treatment of steels and their processing and optimization to meet specific product needs, which will provide a solid foundation and understanding of the significance and impact of heat treatment processes in product design, whether you:
  • Are seeking ways to cut costs, improve performance and increase profitability.

  • Have employees who want to learn more about complementary or competitive technologies.

  • Have employees who want to update present knowledge of heat treatment of steels, processing, and optimization.

  • Have employees who are just starting out in the field and need a basic knowledge of heat treatment of steels.


Interactive learning opportunity .   Participants will join in discussions guided by course instructors, Dr. Jacob Stiglich and Dr. T. S. Sudarshan, who will encourage questions, comments, and participation at all times. There will also be opportunities to exchange ideas with the instructors and other participants during breaks, lunch, and after class adjourns. With this interactive format and the dynamic instructors, participants will find this intensive course to be extremely beneficial, as well as motivating and thoroughly enjoyable.


Key Course Topics.   This excellent practical course can help engineers and technicians choose the most efficient surface heat treatment techniques that offer consistent and repeatable results. The ways in which metal alloys are structured, how the structure affects their performance, how mechanical properties of metals are measured, and what influences these properties; what steels and cast irons are and what processing and chemical parameters influence their performance; how the environment affects the performance and durability of metals -- and much more, as shown in the Course Highlights listed below.
