D28 Nitrided 3D Welding Work Table For Steel Fabrication is a high - end 3D welding workbench that adopts nitriding treatment technology. The model is D28. It is specifically designed for steel structure manufacturing and heavy - duty metal processing, and it is an advanced tooling system with three - dimensional positioning capabilities.
Nitrided Surface (D28 Nitrided)
Surface Hardening: Through the nitriding heat treatment process, the surface hardness can reach HV900 - 1200 (about HRC65 - 72)
Enhanced Wear Resistance: The wear resistance is 3 - 5 times higher than that of ordinary workbenches
Corrosion Resistance: A dense nitride layer is formed, significantly enhancing the rust - proof ability
Accuracy Maintenance: The deformation after treatment is extremely small, maintaining the initial accuracy for a long time
3D Modular System
Three - dimensional Positioning: Precise positioning can be achieved in the X/Y/Z three directions
D28 Standard Hole System: Standard positioning holes with a diameter of 28mm
Multi - layer Structure: Usually equipped with a height - adjustable column system
360° Working Space: Supports all - around positioning and welding of three - dimensional workpieces
