Solar’s Souderton plant recently received a Nadcap accreditation in carburizing, allowing it to better serve the aerospace market. This accreditation joins Solar’s other Nadcap approvals for heat treating, brazing and fluorescent penetrant inspection. Additionally, earlier this year the company became an approved supplier for General Electric Aviation (GEA), UTC Aerospace Systems (UTAS) and Moog Corporation.
Results of study of steel carburized at low pressure using a vacuum furnace show no evidence of hydrogen embrittlement, which should relieve any concern of the possibility of such an occurrence in low pressure gas carburizing.
A proposed technique of determining the actual required flow rate of the carburizing gas into a furnace to provide the necessary amount of carbon for a given work load.
Vacuum carburizing has become one of the hottest topics in the heat treat industry and the development of low-torr range carburization is an important advancement for metallurgical applications.
