Nadcap Heat Treating Approval Logo

Bright hardening and carburizing of alloy steels

Solar Atmospheres new Nadcap accredited vacuum oil quench thermal processing, with a 36” x 36” x 48” vacuum oil quench furnace, capable of safely quenching 2,000-pound loads without carbon potential concerns. With a 2000°F operating temperature and a 3,500 gallon capacity oil tank with a fully integrated SBS oil cooling, heating and filtration system. Processing materials under a protective atmosphere with an oil quench, providing precise results and repeatability.

The furnace’s unique capabilities tie vacuum processing for zero decarburization, along with fast quench delay provisions for an immediate oil quench immersion. It is the fastest cooling vacuum furnace in the Solar fleet, and one of only a few of its kind in the U.S.
