1, high contact fatigue strength.
2, heat treatment should have high hardness, or can meet the requirements of the use of bearings hardness.
3, high wear resistance, low coefficient of friction.
4, high elastic limit.
5, good impact toughness and fracture toughness.
6. Good dimensional stability.
7, good rust resistance.
8. Good cold and hot working properties. |
