Alloy Structural Steel Blades

Our Alloy Structural Steel Blades are manufactured from premium alloy steels specifically formulated for high tensile strength, wear resistance, and durability in demanding industrial environments. The composition is carefully engineered to balance hardness with toughness:

• Chromium-Molybdenum Steel (e.g., 4140 grade): Provides excellent hardenability and impact resistance, ideal for cutting structural sections and high-tensile materials
• Vanadium-Enhanced Alloys: Improves wear resistance and promotes a fine grain structure for superior edge retention during prolonged cutting operations
• High-Speed Steel (HSS) Variants: Such as HSS DMO5 (DIN 1.3343/AISI M2) with tungsten and molybdenum for hot hardness, maintaining cutting edge integrity at elevated temperatures
• Specialized Coatings: Optional TiN, TiCN, or AlTiN coatings available to reduce friction, enhance wear resistance, and improve heat dissipation during high-speed cutting 

Each blade undergoes controlled heat treatment processes including hardening and tempering to achieve optimal hardness levels typically between HRC 60-65, ensuring maximum performance in structural steel cutting applications

Selecting the right blade depends on multiple factors related to your material, equipment, and production requirements. Consider these key aspects for optimal performance:

1. Material Characteristics: Determine the tensile strength and hardness of the material being cut. For high-tensile steels above 800 N/mm², blades with cobalt content (like HSS-Co5) are recommended
2. Tooth Geometry and Pitch: Choose tooth forms based on application - straight (A) for general cutting, beveled (B) for thin materials, or chip-breaker (HZ) for solid sections. Ensure 3-8 teeth engage the material simultaneously for smooth cutting 
3. Blade Dimensions: Match diameter (typically 160-600mm) and thickness (0.8-6.0mm) to your machine specifications and material cross-section. Larger diameters handle thicker materials 
4. Cutting Speed and Feed Rate: Maintain appropriate surface speeds (for cold cutting) or higher speeds (100-140 m/s for friction cutting) based on your cutting method and material type
5. Machine Compatibility: Ensure the blade's bore diameter and pin holes match your equipment. Consider automatic vs. manual operation requirements

Our technical team can provide detailed recommendations based on your specific material specifications and production goals to ensure optimal blade selection 

Proper maintenance is crucial for extending blade life and maintaining cutting precision. Follow these guidelines to ensure optimal performance and cost-effectiveness:

• Regular Cleaning and Inspection: Remove metal chips and abrasive residues after each use. Regularly check for tooth damage, cracks, or signs of abnormal wear that might affect performance and safety
• Professional Sharpening Services: Utilize precision sharpening when teeth become dull. HSS blades can be resharpened multiple times economically, restoring the original tooth geometry without compromising the heat-treated properties
• Correct Storage Practices: Store blades in dry, temperature-controlled environments using protective covers. Hang vertically or lay flat to prevent warping, and avoid contact with corrosive substances
• Operational Monitoring: Avoid excessive feed pressure which causes overheating. Ensure proper cooling when required (except for friction blades where coolant is applied only after cutting) 
• Balance and Tension Checks: Regularly verify proper blade tension and balance on the machine to prevent vibration issues that lead to premature wear and poor cut quality 

Following these maintenance practices can extend blade life significantly, with some users reporting over 70% improvement in time between sharpening intervals
