The key material options for circular dish slitter knives include:
1. High-Speed Steel (HSS): Known for toughness, wear resistance, and the ability to maintain sharpness, especially at high temperatures. Ideal for cutting harder materials but generally more expensive.
2. Tungsten Carbide: Extremely hard with excellent wear resistance, suited for cutting tough materials like metals and abrasive composites. However, it is brittle and may crack under heavy impact.
3. Tool Steel (e.g., D2, SKD11, 52100): Offers good all-around performance at an affordable cost, with decent wear and corrosion resistance. Common in shear slitter knives; D2 has higher wear resistance than 52100 but lower shock resistance. Tool steels can be heat treated for hardness and toughness balance.
4. Ceramic: Provides outstanding wear and corrosion resistance, maintaining a sharp edge, especially useful in high moisture or chemical environments. More brittle and prone to breaking under impact.
5. Stainless Steel and Carbon Steel: Stainless steel offers corrosion resistance suitable for food or wet environments, while carbon steel tends to be sharper and tougher for heavy-duty cutting.[2]
6. Advanced Materials like CPM-10V (a particle metal steel) offer top-tier wear resistance for high-speed, long-run slitting applications, mostly in paper converting industries.
These materials are chosen based on cutting material type, hardness, wear resistance needed, shock resistance, and environmental conditions. The right match improves durability, cutting quality, and reduces downtime.
