Proposal for Ensuring Hardness! Introduction of Case Studies on Increasing Hardness by Changing to Heat Treatment "Salt Quenching"
This is a case study that succeeded in extending the lifespan by changing the heat treatment method of S55C to "salt quenching." [Consultation Details] The S55C shaft was being hardened using vacuum oil quenching, but hardness could not be secured. [Solution Case] We proposed changing to salt quenching, which has good heat transfer, and upon performing the quenching, we were able to secure the hardness. Additionally, the salt quenching eliminated uneven hardening and resulted in a fine hardened structure, contributing to the extended lifespan of the product.
