"Which blade material is best suited for my industry?" This is the question we get asked most often. The answer is straightforward: no single material is suitable for all situations. The quick reference chart below will help you pinpoint the right choice for your specific application.

Industry vs. Recommended Blade Material — Quick Reference
| Industry / Application | Recommended Material | Why? |
|---|---|---|
| Household paper processing (tissue log saw blade, paper cutting blade) | Alloy (carbide) | Extremely high wear resistance, fewer tool changes required for continuous production, and lower overall cost. |
| Printing and packaging paper cutting (paper cutting blade, three-knife trimmer blade) | High-speed steel (HSS) or powder metallurgy (PM) | Good toughness — withstands frequent starts, stops, and minor impacts. |
| Plastic recycling and shredding (shredder blade) | Tool steel — Cr12MoV / D2 | High impact resistance, prevents cracking, and can be re-ground multiple times. |
| Plastic pelletizing (pelletizer cutting blade) | Alloy (carbide) or high-speed steel (HSS) | Carbide delivers long service life for high-filler materials; HSS is economical and practical. |
| Melt filter scraper blade | Alloy (carbide) | Prolonged contact with the mesh plate demands high wear resistance while maintaining cutting edge integrity. |
| Food processing (food blade) | Stainless steel or alloy | Must be rust-proof, corrosion-resistant, and meet food-grade requirements. |
| Metal slitting shear (rotary slitting blade) | Carbide or powder metallurgy (PM) | High hardness, high wear resistance, smooth cut surface without burrs. |
| Press brake mold / shearing machine blade | Tool steel — Cr12MoV / 42CrMo | High strength and deformation resistance, suitable for heavy-duty stamping. |
| Construction machinery accessories (wear-resistant parts) | Low-alloy high-strength steel or hardfacing weld | Impact resistant, wear resistant, and adaptable to harsh working conditions. |
Quick decision guide
Technical Note
FOR LONG LIFESPAN & FEWER TOOL CHANGES → Choose carbide. FOR TOUGHNESS & COST-EFFECTIVENESS → Choose high-speed steel (HSS). FOR RUST PREVENTION & FOOD CONTACT → Choose stainless steel. FOR IMPACT RESISTANCE & HEAVY-DUTY OPERATION → Choose tool steel.
