Heat Treated like our other tongs Stronger than low-carbon steel with equally good machinability, 1045 carbon steel is widely used for bolts, studs, and shafts. Ground rods are decarb-free for a uniform surface that will consistently accept heat treating. 1045 Steel Heat Treatment Normalizing 1045 normalizing temperature range is 830-900 °C and the typical normalizing temperature is 860 °C. Austenitizing The austenitizing temperature for SAE 1045 induction hardening carbon steel is 800-845 °C.
