Welded Carbide Blades

Shengao Welded Carbide Blades are engineered with premium materials to ensure extreme hardness and superior wear resistance:

• Tungsten Carbide Tips: Brazed onto high-strength steel bodies for exceptional hardness (HRA 90+) and 5-10x longer lifespan than standard blades
• Cobalt Binder (6-12% Co): Enhances toughness and impact resistance while maintaining extreme hardness for demanding applications
• Advanced Coatings: PVD/CVD coatings (TiN, TiCN, Al₂O₃) reduce friction, prevent material adhesion, and resist heat build-up for cooler, cleaner cuts
• Specialized Steel Bodies: High-strength steel substrates provide structural integrity and vibration damping during cutting operations

Each material undergoes specialized brazing and heat treatment processes to achieve optimal hardness (HRA 89.5-93.5) while maintaining structural integrity for precision cutting.

Selecting the appropriate welded carbide blade depends on several critical factors:

1. Material Type: Different materials (stainless steel, titanium alloys, hardened steels, composites) require specific carbide grades and coating combinations
2. Material Thickness: Thicker materials require blades with larger diameters and specific TPI (3-14) configurations for optimal cutting efficiency
3. Production Speed: High-speed applications need blades with specialized tooth geometry and advanced coatings for heat management
4. Cut Quality Requirements: Fine-cut applications require blades with more teeth and specialized edge preparations for precision finishing
5. Machine Compatibility: Ensure the blade specifications match your equipment's power, speed capabilities, and mounting systems

Our technical team provides customized recommendations based on your specific cutting requirements and machine specifications.

Proper maintenance extends blade life and ensures optimal cutting performance:

• Regular Cleaning: Remove metal chips and debris after each use to prevent buildup and maintain cutting efficiency
• Proper Storage: Store blades in original packaging in dry, organized containers to prevent corrosion and damage
• Edge Inspection: Regularly check cutting edges for wear, chipping, or damage; replace when cutting efficiency decreases
• Coolant Management: Maintain proper coolant concentration and flow for temperature control in high-speed operations
• Rotation Practice: Rotate blades in multi-station tooling to ensure even wear distribution and extended service life

Shengao offers professional recoating services and provides detailed maintenance guidelines with every purchase to maximize your investment.
