Technical Advantages & Manufacturing Standards

  • Premium Grade Metallurgy: Available in premium 38MnB5 Boron Steel for ultimate impact toughness, or high-tensile 65Mn Carbon Steel for cost-effective heavy-duty performance.

  • Advanced Through-Hardening Heat Treatment: Automated heat-treatment lines guarantee a consistent hardness of 48 to 52 HRC from the cutting edge to the center, completely eliminating the risk of field breakage or premature wear.

  • Precision Formed Concavity: Utilizing advanced hydraulic stamping presses to ensure precise concavity and curvature alignment, resulting in optimal soil turning and minimal tractor drag.

  • Self-Sharpening Cutting Edges: CNC-machined bevel edges deliver a sharp, clean cut through dense crop residue and hardpan soils while maintaining self-sharpening capabilities over time.

  • Versatile Center Hole Configurations: Fully customizable center bores including Square (e.g., 1", 1-1/8", 1-1/4"), Round, Hexagonal, or multi-bolt patterns to seamlessly fit major global implement shafts.

  • Corrosion-Resistant Eco-Coating: Finished with powder coating or high-gloss baking varnish (≥60 μm) to prevent rust during sea transit and outdoor yard storage.
