Heat Treating Overview
Several different heat treating processes are used to modify the microstructure of carbon steel in order to obtain specific strength, wear, forming, and machining properties. These heat treatments include annealing, normalizing, through hardening, and case hardening.
This lesson gives brief explanations of the different types of heat treatments, their thermal profiles, and their objectives. Other lessons are available that provide more details about each heat treating process.
The carbon steel heat treating processes you will learn about
- Three annealing processes – full anneal, recrystallization anneal, and spheroidize anneal
- Through hardening processes – quench and temper, martemper, austemper
- Case hardening processes – carburizing, carbonitriding, nitriding, nitrocarburizing, flame hardening, induction hardening
We recommend that you take the lessons below prior to taking the Heat Treating Overview lesson
"A group of us took several courses (Principles of Metallurgy, Metallurgy of Steel, Corrosion of Metals) to become more knowledgeable about the science of metals to avoid problems. For me, the biggest impact of the training was on working with suppliers. I feel more confident asking questions and I now know the suppliers which know their stuff and which ones don’t. And it was great being able to get the training when it was convenient for me."Sam Bloodgood, VP Process Improvement, Hydraforce, Inc.
"I oversee several operations, including steel heat treating and laser welding. However, my background was in the construction materials industry. Principles of Metallurgy gave me the knowledge to have meaningful discussions with my engineers and be able to ask them better questions."Tom Parkman, Plant Manager, Simonds International.
“Principles of Metallurgy exceeded my expectations. The content was straightforward enough not to be burdensome, yet deep enough to provide a practical review of fundamental principles. I recommend this course to any engineer or technical person who has been out of school and working in industry for several years, but not necessarily having been focused on metallurgy.”Andy Jacobs, Staff Engineer, DePuy Orthopaedics, Inc.
“The Principles of Metallurgy course is broke up into convenient length modules that can be fit into the busiest schedule. The course is a good review for engineers who had a materials class ten or more years ago.”Paul Flury B/E Aerospace
“This is an excellent course (Metallurgy of Steel Heat Treating) for learning basic heat treating practices. The course introduces and covers a broad range of processes. I would recommend it for anyone in the steel business.”Jim Marks, Magellan Corporation
“This course 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, Abbey Forged Products
