In-house Gear Induction Hardening for Quality and Reliability


A surface heat treatment process in which iron or steel absorbs carbon when the metal is heated, with the intent of making the metal harder and stronger (3310, 4320, 4820, 8620, 18CrNiMon7, etc.)

  • Newly installed pit carburizing furnaces
  • 1 pit 2.0m diameter x 2.5m depth
  • 1 pit 2.5m diameter x 2.0m depth
  • Other pit carburizing furnaces
  • 2 pits 1.0m diameter x 1.5m depth
  • 2 pits 2.0m diameter x 4.5m depth

Gear Induction Hardening

A form of surface heat treatment in which a metal part is heated by induction heating and then quenched.

  • Newly installed CNC gear induction hardening machine
  • Gears to 5.0m diameter x 0.75m face
  • Shafts to 3.0m length x 1.25m face
  • Optimized for gear pitches of 3.0DP to 0.75DP
  • Nondestructive ultrasonic case depth testing

Through Hardening

Carbon and alloy steels (1045, 4130, 4140, 4330v, 4340, etc.) that are hardened to ranges between 200 – 400 BHN.
