Solar Atmospheres’ Greenville, S.C., facility has expanded its scope of Nadcap approval to include vacuum furnace brazing for the growing aerospace manufacturing cluster in the southeast U.S. The plant also announced an expansion to its current scope of Boeing approval to include the processing of Precipitation-Hardening, Corrosion-Resistant and Maraging Steel parts to the requirements of AMS 2759/3.

Solar’s Greenville facility now has an approved scope of processing for Boeing that includes the following specifications:

  • BAC 5613 – Heat Treatment of Titanium and Titanium Alloys
  • BAC 5616 – Heat Treatment of Nickel-Base and Cobalt-Base Alloys
  • BAC 5619 – Heat Treatment of Corrosion-Resistant Steel
  • AMS 2759/3 – Heat Treatment of Precipitation-Hardening, Corrosion-Resistant and Maraging Steel Parts


With thermal processing in furnaces ranging from those suited for small lots and development cycles to a 6.5-foot-diameter x 24-foot-long vacuum chamber capable of processing up to 50,000 pounds at 2400°F, Solar Atmospheres is backed by AS9100 and Nadcap quality systems.
