Heat Treating: Atmosphere vs. Vacuum
Which Furnace Option is Best for You?
Atmosphere hardening requires parts to be heated in a controlled atmosphere (neutral to the metal composition), quenched appropriately and tempered to reduce brittleness while maintaining the desired physical properties. In vacuum hardening, air (oxygen) is removed from the furnace, and parts are heated – with or without a partial pressure of inert gas – to protect the surface during hardening. Quenching options are selected based on the materials being hardened and their final-property requirements (i.e., microstructure, hardness, strength, etc.).
This webinar will discuss the differences between atmosphere and vacuum heat treating, including the quenching options available for vacuum furnaces. It will also provide insight into the advantages of vacuum, solutions to vacuum leaks and the types of vacuum furnaces available. The presentation will be followed by a moderated discussion.
Learning Objectives:
- Explain how heat treating creates the desired material properties through hardening, quenching and tempering.
- Describe the general differences between vacuum and atmosphere hardening.
- Identify vacuum furnace quenching choices.
- Explore the available vacuum-system options.
