The exhibitors from Rübig will be presenting the advantages of under-pressure carburizing, also known as low-pressure carburizing (LPC), with subsequent gas quenching as a modern alternative to case-hardening. Compared to classic gas carburizing with oil quenching, it makes use of the advantages of vacuum technology combined with gas quenching, as the company explains. LPC offers optimum uniformity also with complicated component geometry and enables denser charging as well as clean, bright surfaces free from oxidation on the edges. Applicable material grades are air-hardening steels and high-alloy steels such as 18CrNi8 or 18CrNiMo7-6 as well as materials for special applications such as motorsport and aviation like 300M, NC310YW and M50Nil.
Low-pressure carburizing as a variant of case hardening
Compared to conventional gas carburization with oil quenching, the advantages of vacuum technology in combination with gas quenching are used in this process.
