Atmosphere Heat Treating Process Austempering is a form of heat treating that when applied to certain metals allows for greater tensile strength, more consistent hardness, and lower distortion when compared with conventional treatments.
Oct 06, 2009 · A key heat-treat consideration is the creation of an atmosphere within the furnace that is neutral to the parts being processed. This can be done a number of ways and depends on the temperature of the process and the carbon content of the parts.
About Heat Treating & Heat Treat Furnaces. Heat treating (or heat treatment) broadly refers to a group of thermal processes in industrial and metalworking applications used to intentionally alter the physical, and sometimes chemical, properties of a material (usually a metal). These physical and chemical property alterations typically come in
Jun 12, 2018 · Carbon (oxygen) probes, shim stock or carbon analyzers and dew point are typically used to measure the carbon potential of the endothermic atmosphere in a heat-treatment furnace. An infrared analyzer can also be used.
Apr 25, 2014 · A furnace with a mechanical pumping system alone removes enough air that there will be no apparent surface reactions (discoloration) during heat treating of most common metals like stainless steels or tool steels.
This series of box-type heat treatment furnace is a periodic operation heat treatment equipment, which chamber's maximum temperature can reach 1000 ℃, and can continuously work at 950 ℃ or lower temperature.

ABOUT For over 30 years, Heat Treat Furnaces has been designing, fabricating and installing custom furnaces for our industrial clients. HTF's experienced engineers and support staff are focused on your project. Our industrial furnaces have an extensive list of capabilities and can be manufactured to suit almost any application.
SEALED BOX VS ALLOY RETORT. The most common way to "contain" a protective atmosphere is to externally seal the furnace case and simply purge the interior of the furnace with the atmosphere. Typically, L&L does this by welding the case seams (when a combustible atmosphere is used we typically double weld the seams).
When your requirement for a new vacuum or atmosphere furnace system arises, we may have what you're looking for available with short lead times and/or ready for immediate shipment. Heat treatment furnaces for sale

heat treatment is the type, consistency and control of the furnace atmosphere. The purpose of a furnace atmosphere var-ies with the desired end result of the heat-treating process. The atmospheres used in the heat-treat industry have one of two common purposes: † To protect the components being pro-cessed from harmful chemical reactions
It takes a vacuum heat treatment furnace to achieve these results. Essentially, parts are positioned in a special chamber. Oxygen is removed from the chamber and replaced with (usually) argon gas. The chamber is heated to up as much as 2400 degrees F. at a controlled rate, and then the temperature is lowered.

Heat treat furnaces are different from re-heat in that the produced atmosphere is in direct contact with the steel instead of being isolated. Heat treat atmospheres may be comprised of oxygen, carbon monoxide, carbon dioxide, hydrogen, or methane.
The makeup of a furnace's atmosphere in the heat treating process varies based upon the application. For carburizing, sensor technology allows for the in-situ monitoring of furnace atmospheres but many assumptions are made when calculating carbon potential based on the prepared atmosphere being used.
A second preheat step at 1850/1900°F is recommended for vacuum or atmosphere furnaces when hardening temperature is over 2000°F. (2) Higher austenitizing temperatures are used for slightly greater hardness; lower temperatures may provide slightly improve toughness.
Can-Eng Furnaces International Limited has the depth of experience to custom engineer heat treating equipment for the most demanding application, providing innovative, state-of-the-art equipment that helps our customers improve their bottom line and gain a competitive edge.
