Vacuum Hardening & Tempering
Vacuum hardening prevents high temperature oxidation and decarburization, while gas quenching from vacuum minimizes distortion over traditional oil quenching.

Vacuum Brazing
Solar Atmospheres
Fluxless vacuum brazing services from Solar Atmospheres allows you to join metals while keeping the assembly bright and clean. Unlike soldering or welding, even complex shapes can be brazed with little distortion.
Vacuum Stress Relieving
Solar Atmospheres
Welding, machining, milling, and cold working all induce stresses within materials. These stresses will cause unstable dimensional control downstream if not relieved thermally. Vacuum metal stress relieving is normally performed after rough machining, prior to final machining. Solar's vacuum metal stress relieving produces bright, clean surface finishes, therefore often the part is stress relieved in a near net shape.
Vacuum Annealing
Solar Atmospheres
Solar Atmospheres provides vacuum annealing services to millions of pounds of materials every year. The primary reason most customers desire an anneal heat treatment is to reduce hardness and increase ductility making the metal more workable for subsequent downstream operations.

Vacuum Age Hardening
Solar Atmospheres
Certain metal alloys may be strengthened by a relatively low temperature process called precipitation age hardening. As in annealing, brazing, and stress relieving, vacuum age hardening may assure the parts remain bright at the outset. Precise temperature control is paramount in vacuum age hardening and many times Nadcap accreditation and ITAR registration are requirements.

Vacuum Degassing Services
Solar Atmospheres
Vacuum degassing services remove detrimental elements such as hydrogen, nitrogen and oxygen, which may be harmful to the integrity of the metal. Hydrogen is one of the more common interstitial impurities which requires degassing. Vacuum degassing can be used for very small impurity levels (<100 ppm) to very high hydrogen levels.

Description
As in annealing, brazing, and stress relieving, vacuum metal processing of tooling and high strength steel can give you an advantage over conventional hardening and tempering. Vacuum hardening prevents high temperature oxidation and decarburization, while gas quenching from vacuum minimizes distortion over traditional oil quenching. Vacuum tempering keeps parts bright and clean with no temper scale.
