Blade Steels – Materials for Industrial Cutting Blades

The steel used in industrial blades determines performance, durability, and cost-efficiency. Different steel grades are chosen depending on the application, balancing hardness, toughness, corrosion resistance, and wear resistance.

🔹 Carbon Steel:

A cost-effective option offering sharp edges and good hardness, but with lower corrosion resistance. Commonly used for single edge blades, scrapers, and general-purpose cutting where blade replacement is frequent.

🔹 Stainless Steel

Combines corrosion resistance with durability. Often based on high-carbon stainless grades (e.g., AISI 440A, 440B, 440C), stainless blades perform well in packaging, food, and medical industries where hygiene and moisture resistance are important.

🔹 Tungsten Carbide

A composite of ~88% tungsten carbide and 12% cobalt binder, offering extreme hardness (HRC ~92) and exceptional wear resistance. Used in slitting foils, films, technical fibers, and recycling where blade life must be maximized.

🔹 Recycled Tungsten Carbide

An eco-friendly alternative with similar hardness to virgin carbide, offering sustainability and cost savings, though with a slightly shorter blade life. Ideal for customers prioritizing green manufacturing solutions.

🔹 High-Speed Steel (HSS / M2)

Designed to retain hardness even at elevated temperatures. Offers toughness and edge retention, making it suitable for rotary, oscillating, and CNC blades cutting textiles, composites, and thicker materials.

🔹 ASP Steel (Powder Metallurgy Steel)

Premium tool steel made through powder metallurgy, offering a fine microstructure, excellent wear resistance, and stability under extreme loads. Often used in pelletizer knives and recycling blades.
