Redefining Transmission Efficiency
In the manufacturing of automotive gearboxes, heavy-duty gears, and high-strength shafts, every microscopic structure of the material determines the reliability of the final product. Haihui Steel’s 20CrMnTi precision seamless tubes, through precise chemical composition control (Cr-Mn-Ti system), provide you with a more balanced carburized layer and superior fatigue resistance.
Why is Haihui 20CrMnTi Your Ideal Choice?
Excellent Carburizing Performance
20CrMnTi is a classic carburizing steel. By strictly controlling the titanium (Ti) content, we achieve grain refinement, ensuring that the core of the parts maintains high toughness after high-temperature carburizing while achieving uniform surface hardness.
Cost-Efficiency Solution: “Tube Instead of Bar”
For components such as hollow gears and universal joint sleeves, replacing solid bar stock with Haihui ±0.05mm high-precision tubes can directly reduce drilling time by 30% and improve material utilization by over 20%.
Ultra-Fine Surface & Dimensional Tolerance (5-Micron Precision)
The dimensional tolerance is consistently controlled within ±0.05mm. The exceptionally high concentricity ensures minimal cutting allowance during high-speed automatic lathe machining, significantly extending tool life.
100% Digital Non-Destructive Testing (100% NDT Tested)
Each 20CrMnTi component undergoes dual inspection via eddy current and ultrasonic testing to ensure the absence of internal microcracks and inclusions, meeting the stringent requirements of Tier 1 automotive component suppliers.
