Metallurgical Insights Pt.1: Induction Hardening Temperatures
December 2nd, 2010
The required induction hardening temperature range, even for AISI 1042 plain carbon steel, depends on not only the heat intensity but also the material’s prior microstructure:
• 1620 to 2000°F (880 to 1095°C), for annealed prior microstructures
• 1550 to 1830°F (840 to 1000°C), for normalized prior microstructures
• 1510 to 1710°F (820 to 930°C), for steels having quenched and tempered prior microstructures.
