Hardening-Quenching & Tempering
.jpg)
After heating and holding the steel in a quenching furnace under manufacturing conditions appropriate for each steel material, it is rapidly cooled and transformed into a martensite structure. As the steel is too hard and brittle in its quenched state, it is heated again in a tempering furnace to give it toughness and adjust the hardness to the specified specifications.
<Materials> S30C to S55C, SCM415, 420, 435, 440, SCR420(H), 435,

Annealing
Softening/spheroidizing annealing/stress relief annealing, Normalizing.
After heating and holding the steel in a heating furnace under manufacturing conditions appropriate for each steel material, the steel is slowly cooled in the furnace to soften it or relieve stress.
