3. Core Advantages
* Extremely strong resistance to seawater corrosion and cavitation: the first choice for ships and marine equipment;
* Wear-resistant, anti-galling, heavy-duty pressure-bearing: suitable for bushings, worm gears, and bearings;
* Fatigue-resistant and high-temperature resistant, maintaining high strength even at 400℃;
* Resistant to salt spray, weak acid, and alkaline media corrosion.
4. Typical Application Scenarios
* Aviation and military bearings, drilling rig guide sleeves, rock drill bit bushings; Marine engineering and shipbuilding high-pressure wear-resistant rings, seawater pump bushings, valve seats; Engineering machinery heavy-duty bushings, worm gears, cams; Military track bearings, hydraulic wear-resistant parts.
