Product description

Highlights at a glance

  • Multi-Standard Alloy Compliance: Matches SAE 4340 (AISI), UNS G43400, 36CrNiMo4 (EN), and SNCM439 (JIS) specifications, ensuring compatibility with global industrial standards.
  • Ultra-High Strength & Toughness: Cr-Ni-Mo alloy composition delivers exceptional tensile strength (980 1180 MPa) and excellent impact toughness, ideal for high-stress applications like drill pipes and heavy machinery.
  • Quenched & Tempered (Q+T) Heat Treatment: Precision heat treatment achieves tailored hardness (260 320 HB), optimizing both surface wear resistance and core toughness for reliable performance under cyclic loads.
  • Seamless Rolled Ring Structure: Continuous grain flow from the rolling process eliminates welding defects, improving fatigue resistance and structural integrity compared to cast or welded alternatives.
  • Excellent Wear & Corrosion Resistance: Molybdenum and chromium additions enhance surface hardness and corrosion resistance, critical for components operating in harsh drilling and industrial environments.
  • Precision Machinable: Near-net-shape forging minimizes material waste and machining costs, while the uniform microstructure ensures consistent dimensional stability during CNC machining.
  • Rigorous Quality Assurance: Full ultrasonic testing (UT), magnetic particle testing (MT), and mechanical property verification (tensile, impact, hardness) to meet oilfield and industrial equipment standards.
  • Oilfield & Industrial Applications: Designed for drill pipe components, wellhead equipment, heavy machinery spindles, and high-pressure system parts requiring superior strength and durability.
  • Customizable Specifications: Available in a wide range of diameters and wall thicknesses, with custom heat treatment and machining options to meet exact project requirements.
