Ball and Roller Bearing Steels : 3505

Main Characteristic

3505 is in the class of low alloy steel which contain approximately carbon 1%, Chromium 15%.
This help make deep hardening. Also , provide with high hardness after heat treatment.
Result in good performance in wear and abrasive resistance. Give us high hardness after
queching before tempering (62-66 HRC). And after tempering, hardness is in the range of 58-62 HRC.
Besides, this can do induction to enhance surface hardness which can stand for wear, abrasive together
with toughness. Suitable for bearing , milling ball, gear, spring bush, bush, guide post and application
which need wear resistance.

OutStanding Properties

  High wear resistance
  High abrasive resistance
  Moderate in toughness
  High performance in quenching
  Can do induction

Application

3505 is in the class of high strength steel which still can maintain toughness well.
Also, it can stand well for abrasive due to it can be quenched to high hardness.
Result in popularity in production of bearing needle and case for both ball , rod or needle type.
Besides, it also good for roller, collet, spring ring , gear, bush and guide column, etc since it
give a very high hardness and wear resistance properties.
