Nadcap Carburizing for Souderton
The Souderton plant can better serve the aerospace market with its recent Nadcap accreditation for carburizing. The already stringent review of quality procedures and processes was even more challenging for Solar. The Nadcap audit checklist is based on conventional carburizing processes which 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. In addition LPVC offers controllable, predictable and very uniform case depths as well as the ability to carburize in blind and very small diameter holes.
Solar’s quality and technical departments collaborated extensively to successfully meet Nadcap requirements while navigating the differences between the two processes. Solar passed the audit without any findings and satisfactorily answered all questions. This carburizing accreditation joins Solar’s other Nadcap approvals for heat treating, brazing, and fluorescent penetrant inspection.
