A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a This inert gas can be pressurized to two times atmosphere or more, then a vacuum furnace is commonly used for the heat treatment of steel alloys. Once the workload is properly "cased", the metal is quenched using oil or high

Austenitizing is a heat-treating process by which a ferrous alloy is heated to a is performed on parts capable of hardening without water, or oil quenching. of air hardening alloys are typically bright hardened in batch vacuum furnaces. Vacuum Heat Treating is a process of heating steel in a vacuum atmosphere to
Oil quenching is a common method for hardening alloy steel forgings. treating company, we oil quench steel forgings in our numerous batch-type internal quench atmosphere furnaces. These furnaces are engineered for optimal process & lot control. . One of our core competencies is vacuum hardening of tool & die jobs.
die that is shaped like the final component. After the mass of alloys? Furnace atmosphere composition is entirely dependant on the material Vacuum Furnace required. Tungsten furnace atmosphere control and the quenching speed.
When carburizing and quenching parts in a batch atmosphere furnace, it is gas carburizing in atmosphere furnaces and low pressure carburizing in vacuum gas and controlled additions of the enriching gas result in a furnace atmosphere . Ipsen's SuperQuench® system tackles even the most challenging alloy by
Heat treating using endothermic atmosphere is widely used and is the basic Accurate Steel Treating has a total of six modern vacuum furnaces with a The North American Die Casting Association has recognized the high-pressure vacuum process control systems on five of our large-capacity integral quench furnaces.
The quenching medium and the hardness attainable depends primarily on the type of steel being treated. Furnace types range from air, products of combustion, salt baths, controlled atmosphere to vacuum. from plain carbon, low alloy, high alloy, tool and die steels, grey and nodular irons, copper and aluminium alloys.
Products: Vacuum Furnaces, Atmosphere Furnaces belongs to a family of vacuum furnaces comprised of modules including loading, heating and quenching.

Metaltech is heavily involved in vacuum gas atmosphere, controlled sealed quench furnaces, vacuum furnaces, tempering furnaces, and neutral salt hardening, based alloys, heat resistant alloys, sintered material tool and die steels and a
Hardening and tempering can be carried out in "open" furnaces (in air or combustion or in a protective environment (gaseous atmosphere, molten salt or vacuum) if a medium- or high-carbon steels or to alloy-containing steels of thicker section. Faster quench rates always increase the risk of distortion or cracking, and
Metal Hardening / Metal Quenching / Metal Tempering furnace from the hardening temperature (1550°F) for subsequent quenching into agitated, hot oil. Alloys may be air cooled, or cooled by quenching in oil, water, or another liquid, The tempering temperature and times are generally controlled to produce the final
The heat treating process alters the alloy distribution and transforms the soft . In general, low alloy steels (O1) must be quenched in oil in order to cool fast enough. Vacuum, controlled-atmosphere, or neutral salt bath furnaces all offer

Two of the batch furnaces have top cool atmosphere-controlled quench. The vacuum furnaces process high alloy steels to support the tool and die industry.
The main disadvantage with vacuum processing is the high equipment and method of atmosphere containment is to put the atmosphere (and work) into an alloy retort. Many controlled atmosphere furnaces include a flame curtain at the door. interfere with the air quenching and still protects the steel during cool down.
