Steel for Granulator and Shredder Blades

Have you ever wondered?

• What makes some machine blades last longer in tough recycling environments?
• Why do granulator and shredder blades wear out so quickly if the wrong steel is used?
• How can you maximize uptime while reducing maintenance costs?

In the fast-growing recycling industry, machine blades are at the heart of operations, enabling the processing of plastics, rubber, metals, and more into reusable resources. Among the materials available for manufacturing blades, D2 tool steel has emerged as a clear favorite for granulator and shredder blades — and for good reason.

What is D2 Steel?

D2 is a high-carbon, high-chromium tool steel belonging to the cold-work steel family. Its chemistry typically includes about 1.5% carbon and up to 12% chromium, which delivers exceptional wear resistance, hardness, and toughness. After heat treatment, D2 steel achieves hardness levels of up to 60 HRC, making it one of the toughest cold-work tool steels available.

Advantages of D2 Steel for Recycling Applications

✅ Superior Wear Resistance
Granulator and shredder blades face intense abrasion when cutting plastics containing fillers, or metal-rich waste streams. The high carbon-chromium content of D2 gives it outstanding wear resistance, allowing these blades to hold a sharp edge longer.

✅ High Hardness
Blades made from D2 steel can maintain their cutting edge even under repetitive impact loads, crucial for consistent particle size in granulators or uniform shredding in pre-processors.

✅ Dimensional Stability
Recycling operations demand blades that keep their shape under mechanical stress. D2’s excellent stability minimizes warping and dimensional change, supporting tighter tolerances for consistent quality.

✅ Corrosion Resistance
D2’s high chromium percentage offers good corrosion resistance compared to other carbon steels. This is valuable in recycling environments where moisture or contaminants may cause rust.

✅ Heat-Treatable to Customized Properties
Industrial Sharp Cut, a trusted Indian supplier of machine blades, expertly heat-treats D2 steel to achieve the precise combination of toughness and hardness needed for each customer’s recycling application.

Why the Recycling Industry Relies on D2 Steel

Modern recycling plants process massive volumes of waste material, helping reduce landfill burden and supporting a circular economy. Equipment downtime is expensive — one day of lost shredding or granulating capacity can mean tons of material left unprocessed. Using D2 steel blades means fewer blade changes, more consistent output quality, and better ROI over the machine’s life cycle.
