  • Product Details
  • 20Cr Alloy Steel Seamless Pipe is a premium low-carbon alloy structural steel tube, widely recognized for its exceptional carburizing properties and optimal balance between strength and toughness. Adhering to the GB/T 3077 standard, the addition of Chromium (Cr) significantly enhances the material’s hardenability and wear resistance.

    The defining characteristic of 20Cr is its ability to achieve a “hard exterior and tough core” after surface carburizing and quenching. This makes it the premier choice for manufacturing high-load mechanical components that must endure both heavy friction and sudden impact.

    Technical Specifications
    Outer Diameter (OD): 12mm – 120mm (Customizable)
    Wall Thickness (WT): 1.5mm – 15mm (Customizable)
    Material Standard: GB/T 3077 (Equivalent to AISI 5120 / DIN 1.7027)
    Delivery Condition: Hot-rolled, Cold-drawn, or Annealed/Normalized as per request.

    Primary Applications
    Due to its versatile mechanical properties, 20Cr pipes are extensively used in:
    Automotive & Transmission: Precision gears, piston pins, and splined shafts.
    Mechanical Engineering: Bushings, sleeves, and heavy-duty pins.
    Industrial Components: High-speed spindles and wear-resistant structural parts.
