1. Common High Wear Resistant Tool Steels
- Blades usually made from high‑strength alloy tool steel or cold work die steel.
- Most common materials: Cr12MoV, SKD‑11, D2, and DC53.
- Provide good hardness, wear resistance, and cutting stability.
- Suitable for plastics, wood, rubber, and mixed solid waste.
2. Impact Resistant Steels for Heavy‑Duty Use
- For metal scrap, tires, thick pipes, and mixed industrial waste, some blades use 42CrMo, H13, 6CrW2Si, or LD steel.
- More impact resistant than high‑hardness tool steel.
- Less likely to crack when hard objects enter the crushing chamber.
3. Heat Treatment Determines Blade Life
- Blade performance depends not only on material grade but also on heat treatment.
- Typical blade hardness: around 58 to 63 HRC.
- Vacuum quenching, tempering, and deep cooling treatment improve edge retention and reduce chipping.
- Without proper heat treatment, even high‑grade steel may wear faster than expected.
4. Confirm Blade Material Before Purchase
- For export projects, confirm blade material, hardness range, heat treatment process, cutter thickness, and replacement method.
- Blade material should match the target waste type, expected output, and maintenance budget.
- Material confirmation should always be based on the official specification sheet rather than general description.
