Product Name：

Precision CNC Milled Q345B Flange Ring with Electroless Nickel Plating

Product Description：

This heavy-duty machined component is fabricated from high-toughness Q345B structural steel, featuring a complex geometry with a circular outer flange and a deep square inner cavity. Manufactured using advanced multi-axis CNC milling technology, it incorporates intricate serpentine cooling channels designed for efficient thermal management. The surface is finished with Electroless Nickel Plating (ENP), providing a uniform, corrosion-resistant barrier and enhanced surface hardness without altering dimensions. Ideal for large-scale injection mold bases, hydraulic sealing plates, or industrial machinery frames requiring excellent weldability and durability.
