Blade material selection balances wear resistance, impact toughness, edge geometry and cost. Use the machine specification or approved drawing alongside your feedstock and operating conditions.
A specified lower-alloy tool steel can be economical for less abrasive work. Toughness, wear resistance and resharpening limits depend on the grade, heat treatment and edge design.
9CrSi is a low-alloy tool steel option. Its resistance to chipping and wear depends on heat treatment, edge support and the actual material being cut.
D2 / SKD11 is a high-carbon, high-chromium cold-work tool steel used where abrasive wear matters. Hardness and bevel design must suit the machine duty; impact and contamination can raise chipping risk.
Cemented tungsten carbide can offer a wear-resistant edge in suitable abrasive duties. Solid, inlaid and tipped constructions differ; grade, edge support, bonding and impact loading all affect the result.
Glass fiber, sand and other abrasive contaminants can increase edge wear. Compare suitable tool steels and carbide constructions after checking impact loading.
Hard inclusions or unexpected metal can chip a cutting edge. Review contamination controls, edge support and the specified material before changing grades.
Cutting speed, friction, cooling and edge finish can affect blade temperature. Review these factors before considering high-speed steel (HSS) or another grade.
Compare purchase cost with sharpening, changeovers, scrap and downtime under your operating conditions. Carbide is not an automatic upgrade.
| Material Grade | Hardness Specification | General Characteristic | Selection Check |
|---|---|---|---|
| Carbon Tool Steel | Specify grade and HRC target on the approved drawing | Properties vary widely by grade and heat treatment | Confirm wear, impact and regrind requirements |
| Low Alloy (9CrSi) | Specify heat-treated HRC target for the application | Low-alloy tool steel with grade-dependent wear and toughness | Confirm edge geometry and feedstock contamination |
| Premium D2 / SKD-11 | Specify HRC target on the approved drawing | Good abrasive-wear resistance; impact can cause chipping | Review bevel, impact risk and sharpening limits |
| High-Speed Steel (HSS) | Specify grade and hardness for the duty | Selected grades retain cutting hardness at elevated temperature | Review speed, heat, geometry and the actual HSS grade |
| Tungsten Carbide Inlaid | Specify grade using Vickers (HV) or Rockwell A (HRA), as applicable; do not use an assumed HRC equivalent | Wear-resistant edge; chipping risk varies by grade and design | Confirm solid, inlaid or tipped construction and edge support |
General guidance only. Hardness, material availability and blade construction must be confirmed for the specific drawing and application. Quotation depends on the approved specification and quantity.
Send your machine model, drawing or part number, feedstock and operating conditions so suitable material options can be reviewed.
