TAP TREATMENTS

Type Characteristics Purpose Use
Tap Treatments

Oxidation
(homogenization)
  • Treated layer : 1 – 3 um
  • Oxidized coat layer (Fe304)
  • Porous with cutting oil held in pores
  • Lowered coefficient of friction
  • Prevents fusing
  • Unsuitable for non-ferrous metals for internal threads
 Prevent fusing For internal thread material easily fused to tap materials

  • Stainless steel
  • Titanium alloy
  • Mild steel such as SS400 and S15C
Nitriding
  • Treated layer: 30 – 50 um
  • Surface hardness: 1000 – 1300HV
  • Improve wear resistance
