Inductoheat - An Inductotherm Group Company

Non-uniform coil current density distribution resulting from various electromagnetic phenomena has a dramatic effect on induction heating coil life and crack development in the copper. Coil electromagnetic end effect and copper electromagnetic edge effect are critical factors that should be taken into account when designing “long-lasting” induction coils. The coil copper edge effect that is [...]

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), [...]
