Facts about Sen/Pak® Heat Treating Containers The Sen/Pak System of heat treating utilizes a metal foil container to provide a protective sheath and to automatically neutralize the entrapped atmosphere. The lightweight Sen/Pak container heats more rapidly than the work piece. As a result, the undesirable elements in the entrapped atmosphere react with the Sen/Pak container long before the work piece is hot enough to be damaged by them. In addition, the Sen/Pak container acts as a protective barrier throughout the hardening and quenching operation. The Sen/Pak System is ideal for many tool steel hardening applications when an atmosphere furnace is not available. The range of applications includes hardening of small pieces of molybdenum high speed steels. There are limitations to the use of the containers at high speed hardening temperatures. In addition, many oil and water hardening steels are difficult to quench properly in the Sen/Pak container. For premium hardening of all types of tool steels, Sentry offers the Diamond Block System of atmospheric control.
