Low pressure carburizing (LPC) in vacuum furnaces has many applications in industrial technologies where high quality, reliability and repeatability are required. High quality work is achieved using the patented process control method, FineCarb®, that delivers a precise three gas carburizing mixture injection sequence controlled through a computerized supervision system and process simulation software. The advantage of the LPC method is demonstrated in high alloy and special steels, where a high temperature carburizing process is required and rapid carbon diffusion reduces the process time significantly. In addition, extended hardenability of these steels enables effective gas quenching that reduces distortion as well as manufacturing costs. Vacuum furnaces with gas quenching are a green manufacturing technology, a major improvement over traditional atmosphere technologies.
The article describes actual process trials, results and conclusions carried out with high alloy and special steel grades: Ferrium C61, CSB-50 NiL, N6-5-2 and X5CrNiMo17-12-2, which have many applications in both automotive and aerospace.
