Heat Treatment Spec Table
6 types of spec data
Reference for heat-treatment conditions, pre/post hardness, case depth, and typical applications for the most common materials (S45C, SCM440, SKD11, SUS440C, SUJ2). Covers the six core processes: quench & temper, annealing, normalizing, carburizing, nitriding, and induction hardening. Based on KS D 3752 / 3867 / 3753 / 3706 / 3525. Designed to let engineers decide material and heat treatment together at design time, with practical notes on machining allowance, distortion, and cracking risk.
