Solar Atmospheres of Eastern PA recently received Nadcap approval for carburizing. The Souderton, Pa., plant can now better serve the aerospace market with this accreditation. The Nadcap audit checklist is based on conventional carburizing processes that are controlled by carbon potential, but Solar’s patented low-pressure vacuum carburizing (LPVC) process works a bit differently. The most notable benefit of LPVC over traditional carburizing is the absence of intergranular oxidation (IGO). IGO-free parts eliminate the cost and time required for additional machining. Solar passed the audit without any findings and satisfactorily answered all questions. This carburizing accreditation joins the Souderton plant’s Nadcap approvals for heat treating and brazing.
