Steel Induction and Flame Hardening

Steel Induction and Flame Hardening

Induction and flame hardening heat treatments are used with steels to form a strong, hard case (surface layer) over lower strength, more ductile steel.

The hardness and strength of induction and flame hardened components depends on steel composition and the heat treating steps. Understanding the basics of how these factors affect steel microstructure is key to understanding how to get the desired properties in your components.

You will learn ...

  • induction and flame hardening process steps and process conditions.
  • effects of induction and flame hardening on case microstructure.
  • effects of induction and flame hardening on case strength and hardness.
  • how case hardness and depth are measured.

This course is a strong fit for engineers, designers, technicians, quality professionals, and manufacturing teams who work with metals but do not need to become full-time metallurgists.

The knowledge that you’ll gain from this course will help you make better design decisions, make better supplier selection decisions, and solve quality problems faster.

  • Why induction and flame hardening are used
  • Process steps for induction and flame hardening.
  • Case microstructures that result from induction and flame hardening.
  • Process parameters for induction and flame hardening and their effects on case microstructure, hardness, and depth.

Prerequisites

To get the most from this course, you should be familiar with the concepts taught in our Principles of Metallurgy, Steel Metallurgy, and Steel Through Hardening courses. This includes

  • Metallurgical phases and diffusion
  • Basics of reading iron-carbon phase diagram
  • Phases that form in steel during heating and cooling
  • Effects of cooling rate on phase transformations and steel microstructure formed
  • Steel hardenability

The Steel Metallurgy and Heat Treating Bundle includes this course and the prerequisite courses.

Course content

The modules and their content are:

  1. Introduction. Introduction to the course and steel case hardening.
  2. Process basics and metallurgical changes. Induction and flame hardening process steps. Microstructure and hardness changes that occur when steel is induction or flame hardened. Reasons for using induction or flame hardening instead of furnace through hardening. Composition and microstructure requirements for steel to be induction or flame hardened.
  3. Measuring case hardness and depth. How case hardness and depth are measure. Difference between total and effective case depth.
  4. Induction hardening process details. How induction is used to heat steel. Induction hardening process variables and their effects on case depth. Common induction hardening problems and their causes.
  5. Flame hardening process details. How a flame is used to heat steel. Flame hardening process variables and their effects on case depth. Common flame hardening problems and their causes.
  6. Review.
  7. Final exam. 70% required to pass the course and receive a certificate of completion.

Knowledge checks throughout the course give opportunities to apply the metallurgy concepts taught. The course takes about three hours to complete.

You will have 4 months access to this course.

Course certificate

A certificate for 3 training hour (0.3 CEUs) will be awarded after completing all course modules and successfully completing a final exam.


What people say about our courses

Engineers and technical professionals use this course to build practical metallurgy knowledge they can apply in design, manufacturing, quality, and supplier related work.

  • "Principles of Metallurgy covered the foundations of metallurgy and effects of manufacturing processes needed to obtain desired mechanical properties. This information has been valuable during my work in both design and manufacturing. I highly recommend it for someone that could benefit from knowledge of the fundamentals of metallurgy."
    Chris M.
    Mechanical Design Engineer

  • The Principles of Metallurgy course was a great refresher and supplement to the Properties of Materials course I took in college. The content focuses on information relative to industry, which will help greatly in my day-to-day job functions.

  • Well worth the time to do Metallurgy of Steel Heat Treating. It has given me more confidence in my job and given me a better understanding of some of the heat treatments used in the business
    Mark Winter
    Test House, Abbey Forged Products
  • I learned a bunch from this course. I needed an understanding of the heat treating and metals for our heat treating process in house. I now have a much better understanding of what is accomplished in the process along with understanding what could be a problem in our process.
