Heat treat scale removal and prevention | Paulo

Oct 2, 2017 There are some instances, however, when heat treat scale prevention is recommended over removal. For example, tool steel and stainless steel parts are often best treated in vacuum furnaces that remove atmosphere from the chamber. With no atmosphere to react to, scale won't form. The parts do not

Heat treating - Wikipedia

Heat treating (or heat treatment) is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves

Amazing Vacuum Furnaces - Heat Treatment Techniques for

Aug 6, 2016 When hardening, carburizing and other surface modification processes are needed, a vacuum furnace with a controllable high-pressure gas quenching is then required. Most popular powder metals use in AM are stainless steel, Inconel, magnesium, cobalt, titanium, nickel, copper, tool steels, and aluminum

Enhanced Properties of 17-7 PH Stainless Steel- Thermal

Apr 15, 2015 Solar Atmospheres developed a unique process for heat treating 17-7 PH (precipitation hardening) stainless steel using vacuum furnace technology. This process enhances the The high alloy content of 17-7 provides excellent corrosion resistance, which is an attractive attribute to the medical industry.

Heat Treating - Laserage

Laserage has been heat treating ceramic material for hybrid microelectronics in high-temperature kilns for over 30 years. Today our heat treating capabilities include salt-pot furnaces, small box ovens, small vacuum furnaces and kilns for heat-treating a variety of materials from nickel-titanium alloys, stainless steels and

Evaluation of carbon diffusion in heat treatment of H13 tool steel

The results showed that stainless steel foil wrapping could restrict decarburization process, resulting in a constant hardness profile as vacuum heat treatment does. However An electrical heated open atmosphere furnace (muffle furnace) was used for all heat treatment processes except vacuum heat treatment process.
