Serrated Cutting Blades

Shengao serrated blades are crafted from premium materials to ensure superior cutting performance and durability:

• High-Speed Steel (M2/M4): Excellent edge retention and wear resistance for general-purpose serrated cutting applications
• Tungsten Carbide: Superior abrasion resistance for cutting abrasive materials and extended service life
• Stainless Steel (420J2/440C): Corrosion-resistant blades ideal for food processing, medical, and wet environments
• Tool Steel (D2/SKD-11): High carbon content for aggressive cutting action and impact resistance
• Specialized Coatings: TiN, TiCN, DLC coatings for reduced friction, anti-adhesion properties, and enhanced durability

Each material undergoes specialized heat treatment and cryogenic processing to achieve optimal hardness (HRC 58-65) while maintaining toughness for precision serrated cutting applications.

Selecting the appropriate serrated blade depends on several critical factors for optimal cutting performance:

1. Material Type: Different materials (fibrous, sticky, abrasive) require specific tooth geometries and blade compositions
2. TPI Requirements: Teeth Per Inch (8-200 TPI) selection based on material thickness and desired finish quality
3. Cutting Speed: High-speed applications need blades with specialized tooth configurations and stability features
4. Surface Finish: Fine-cut applications require blades with more teeth and specialized tooth angles
5. Material Hardness: Harder materials require blades with higher Rockwell hardness ratings and reinforced tooth design

Our technical team can provide customized recommendations based on your specific material properties, machine specifications, and production requirements.

Proper maintenance extends blade life and ensures consistent cutting performance:

• Regular Cleaning: Remove residue after each use to prevent material buildup between teeth
• Periodic Sharpening: Maintain sharp cutting edges every 40-80 operating hours depending on application severity
• Proper Storage: Store blades in dry, temperature-controlled environments with protective coatings
• Rotation Schedule: Rotate blades in multi-blade systems to ensure even wear and consistent performance
• Inspection Protocol: Regular visual inspection for micro-chips, cracks, or abnormal wear patterns
• Lubrication: Appropriate lubricants for specific materials to reduce friction and prevent adhesion

Shengao offers professional blade sharpening services and provides detailed maintenance guides with every purchase to maximize your investment and ensure optimal performance.
