Seamless Honed/SRB Steel Tube

  • 4140 hard chrome plated rod

    Steel 4140 is AISI standard grade, it is a kind of alloy structural steel, equivalent to China standard GB 42CrMo.
    SAE 4140 alloy steel has high fatigue strength and low notch sensitivity, high low temperature impact toughness, no obvious temper brittleness, and is mainly used in the quenched and tempered state. It is used to manufacture high-strength parts and parts with large cross-sections and other stress-bearing components under impact load. Such as high strength Hydraulic cylinder rods, penaumatic cylinder rods, the transmission eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, etc.

     

    4140 chrome plated rod is manufactured through SAE 4140 steel bar, by using high precision centerless grinding and polishing methods, and then chrome plated to a min. plating thickness of 20 microns (0.0008″), 25 microns (0.001″), or other. The chrome plating layer provides corrosion resistance and a highly reflective appearance.

    4140 chrome plated rods are used widely by the hydraulic industries and pneumatic industries, and is also widely usually used for applications where high yield strength and tensile strength is required.

  • Air Cylinder Tubing

    The common alloy No. of air cylinder tubing is 6063 and 6061. They are both great in formability, weldability, and corrosion resistance together with excellent appearance.

    Grand also capable of extruding other alloys no. for air cylinder tubing, for example, 7000 series, 5000 series, 3000 series, 2000 series, and 1000 series, consult our expert engineers to get more info regarding this extraordinary aluminum alloy no.

  • Skived & Roller Burnished Tube

    Applications of Hydraulic honed tubing

    Honed tubing and SRB tubes (skived and roller burnished tubes) are mostly used as cylinder tubes, such as hydraulic cylinder tubes and pneumatic cylinder tubings which are widely used for manufacturing and repairing hydraulic cylinders and pneumatic cylinders. As honed tube usually has very accuracy dimension tolerance and good surface smoothness, so this product is also used where precision dimension or high smooth surface is needed.

  • Chrome Plated Round Bars

    Chrome plated round bar is mostly designed to be used for hydraulic piston rod and pneumatic piston rod manufacturing and repairing. So some people also may call this product hydraulic cylinder rod approximately.

    However, besides the above, chrome plated rods can also be used in applications where high performance surface finishing and high accuracy dimension tolerance are required.

    Here below is the application list of the chrome rods:

    • Hydraulic cylinders (chrome plated piston rods)
    • Pneumatic cylinders / air cylinders (chrome plated piston rods)
    • Guide rods for plastic manufacturing machine and hydraulic machinery
    • Rollers for machines, such as packing machine rollers, printing machine rollers
    • Shaft for machinery, such as Textile machinery center axle, Transport machinery center axle, etc.
    • Ejector rods for injection molding machines
    • Vibration absorbers and pistons for some industrial machinery.
