Steel Application
  • Bearing Bush - Ju Feng offers the steel material that can be used for bearing bush.
    Bearing Bush

    It is widely used in the light industry and is installed for fixing the rotated bearing.The materials of bearing bush we recommend are as below.

  • Machine Parts - Ju Feng offers the steel material that can be used for machining parts.
    Machine Parts

    There are three kinds of material type which are used for machining parts, metal material, non-metallic material, and composite. Also, there are two kinds of metal material, ferrous metal and un-ferrous metal. Ferrous metal material which includes steel, cast steel and cast iron has good mechanical properties (such as strength, ductility, toughness, etc.). The ferrous metal material is obtained easily and its price is cheap. Non-ferrous metal material which has the low density has the advantages of thermal conductivity and electric conductivity.The materials of machining parts we recommend are as below.
