S45CBD

Medium Carbon Steel

The surface is smooth after cold drawing, and the main difference with S45C is that the surface can reach rough turning of grade.
The post-process can be directly used for milling or grinding, which greatly reduces the processing time. Its characteristics and application are the same as S45C. .

Applications requiring strength and impact resistance of the component, because of its high carbon content, therefore, have a higher tensile strength, ductility and wear resistance, but is not suitable for welding or forming.
This steel grade can be supplied in many standard shapes, including round, square, hexagonal, and plate. It generally applicative used in nuts and bolts, axles, rollers, springs, wires, wheel frames, rods, engine parts, stamping dies, hammers, lock washers/lock pin gaskets, turbine rotors, railway tracks, cylinder sleeves, hand tools, screws, railway wheels, gears, garden shears, etc.

Steel Application
  • Gear - Ju Feng offers the steel material that can be used for gears.
    Gear

    There are many types of gears, such as: spur gears, sprocket gears, timing pulleys, helical gears, internal gears, racks, spur bevel gears, curved bevel gears, zero-degree bevel gears, staggered spiral gears, worm gears, Halberd gear. The material of the gear must have strong bending fatigue strength and contact fatigue strength, and the tooth surface must have sufficient hardness and wear resistance, and the core must have a certain strength and toughness.The materials for gear application that we recommend are as below.


  • Machine Tool Spindle - Ju Feng offers the steel material that can be used for machine tool spindle.
    Machine Tool Spindle

    There may be several spindles in a machine. There are many types of spindles, including grinding spindles, electric spindles, low-speed spindles, high-speed spindles, engraving machine spindles, milling machine spindles, lathe spindles, etc. Therefore, the spindle should be made of materials with the highest stability, rigidity and efficiency.The materials for machine tool spindle application that we recommend are as below.


  • Drive Shafts - Ju Feng offers the steel material that can be used for drive shaft.
    Drive Shafts

    In order to allow changes in the alignment and distance between the driving and driven components, the drive shaft contains one or more universal joints and couplings. Therefore, their materials must withstand strong pressure, while avoiding excessive additional weight to increase reverse inertia. The materials of drive shaft we recommend are as below.The materials for drive shaft application that we recommend are as below.


  • Cutting Tools - Ju Feng offers the steel material that can be used for cutting tools.
    Cutting Tools

    There are many types of cutting tools, such as: milling cutters, drills, circular saw blades, reamers, PCD (Polycrystalline Diamond) cutting tools, hole drills, lathe tools, stamping tools, etc. The quality of the cutting tool material will affect the surface quality, cutting efficiency, tool life and other factors. Therefore, the selected tool material should have a high degree of hardness, wear resistance, strength, toughness and heat resistance.The materials for cutting tools application that we recommend are as below.


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

    The material types of mechanical parts include metallic materials, non-metallic materials and composite materials. Metal materials are divided into ferrous metal materials and non-ferrous metal materials. Ferrous metal materials include steel, cast steels and cast irons, which have good mechanical properties (such as strength, ductility, toughness, etc.), and are relatively cheap and easy to obtain. Non-ferrous metal materials have the advantages of low density, good thermal and electrical conductivity.The materials for machining parts application that we recommend are as below.
