Proposal for Ensuring Hardness! Introduction of Case Studies on Increased Hardness by Changing to Heat Treatment "Salt Quenching"
This is a case study demonstrating the successful extension of lifespan by changing the heat treatment method for S55C to "salt quenching (salt bath 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 (salt bath quenching), which has good heat transfer, and upon performing the quenching, hardness was successfully secured. Additionally, the salt quenching eliminated uneven hardening and resulted in a fine hardened structure, contributing to the extended lifespan of the product.
