The Spheroidize Annealing Furnace from HIGHTEMP is ideal for treating steels with over 0.8% carbon, operating at 680°C to 750°C to transform cementite into a spheroidal structure within an alpha ferrite matrix. This process restores machinability in work-hardened parts like bearings, fasteners, wire rods, springs, and gears, improving ductility and toughness while reducing hardness and strength. Conducted under a protective endothermic atmosphere to prevent oxidation and decarburization, the furnace supports low, medium, and high-carbon steels (e.g., 1018, 1045, 1080) and alloy steels (e.g., 4140, 4340). With precision temperature control, electric or gas heating, and automated PLC systems, this high-throughput furnace ensures consistent, efficient, and high-quality results for industries like automotive and tool manufacturing.
Advantages:
  • Improves the ductility of steel components, making them easier to machine and work with.
  • Relieves work hardening in parts, enabling further processes like rolling or wire drawing.
  • Suitable for low, medium, high-carbon, and alloy steels, covering diverse industrial needs.
  • Operates under a protective endothermic atmosphere to prevent oxidation and decarburization.
