Blade Qualities
Material options for industrial cutting solutions
The right blade quality extends service life and reduces costs.
Cutting Blades
Wear resistance vs. impact resistance
Tool Steel (1.2067)
Hardness: 58–60 HRC
Properties: Good impact resistance, good wear resistance
Use: Normal cutting tasks, good value for money
HiChrome D2
Hardness: 58–62 HRC
Properties: Excellent wear resistance, good impact resistance
Use: Demanding cutting applications, durability critical
High-Speed Steel (HSS)
Hardness: 62–65 HRC
Properties: Highly wear resistant, good impact resistance
Use: Demanding cutting and drilling tasks
Powder High-Speed Steel (ASP)
Hardness: 64–66 HRC
Properties: Highest wear resistance and impact resistance
Use: Precision tools, optimal performance
Stainless Steel
Hardness: 54–58 HRC
Properties: Corrosion resistant, good wear resistance
Use: Chemical and food industries
Carbide
Hardness: 89–92 HRA
Properties: Maximum wear resistance
Use: Especially demanding cutting tasks
Recommended combination for maximum cutting results: powder steel (ASP) for the upper blade, carbide for the lower blade.
HiChrome D2 – Hardness, Wear Resistance and Impact Resistance
Effect of hardness on wear resistance and impact resistance
Selecting the hardness range
Powder metallurgy (ASP) breaks this tradeoff: smaller, uniform carbide structure delivers better toughness at the same hardness. When you need both wear resistance and impact resistance, ASP is an alternative to lowering D2 hardness.
Hardox Blades
Wear resistance vs. impact resistance
Hardox 400
Hardness: ~400 HB
Impact resistance: 45 J (–40°C)
Easiest to machine and weld. Light to medium wear.
Hardox 450
Hardness: ~450 HB
Impact resistance: 50 J (–40°C)
Most common choice. Best impact resistance in the series.
Hardox 500
Hardness: ~500 HB
Impact resistance: 37 J (–40°C)
Harder wear, good toughness retained.
Hardox 600
Hardness: ~600 HB
Impact resistance: 20 J (–40°C)
Maximum wear resistance. Avoid impact loads.
