Properties: High hardness, great wear resistance, moderate toughness, well-rounded performance, cost-effective and widely used; minimal quenching deformation.
Hardness: HRC 58–60 (after heat treatment)
Applications: Thin cold-rolled sheet, galvanized sheet, aluminum sheet, copper sheet, and non-metallic materials such as plastic and leather.
Properties: Tungsten and silicon alloyed; excellent red hardness, higher strength than 9CrSi, better toughness and chipping resistance; exceptional wear resistance.
Hardness: HRC 60–62 (after heat treatment)
Applications: Hot-shearing materials, light stainless steel, and medium-strength steel.
Properties: Exceptional wear resistance and hardenability, moderate toughness, small heat-treatment distortion, long service life, impact-resistant.
Hardness: HRC 58–60 (after heat treatment)
Applications: Stainless steel, silicon steel, high-strength steel, various thicknesses of low-carbon steel (Q235), aluminum sheet, copper sheet, and thin mild steel.
Properties: Excellent high-temperature strength, impact toughness, thermal fatigue resistance; stable hardness at high temperatures, resists softening and deformation.
Hardness: HRC 50–55 (after heat treatment)
Applications: Hot-sheared hot-rolled plate, iron plate, medium and heavy plate, scrap metal, hot-sheared strip steel, cold-sheared high-strength alloy steel, and thick stainless steel plate.
Properties: High strength, strong wear resistance, excellent chipping resistance; far better wear resistance and hardenability than general tool steel, high dimensional stability (for D2).
Hardness: HRC 58–62 (after heat treatment)
Applications: Stainless steel, high-strength steel, silicon steel, medium-low hardness plates (Q195/Q235/45# steel/40Cr), aluminum/copper/brass/red copper sheet, and non-metallic materials including plastic, rubber, paper, fiberboard, and composites.
Properties: High strength, good toughness, wear resistance, chipping resistance, and balanced overall performance; vanadium and molybdenum refine grains for high flexural strength and extreme chipping resistance.
Hardness: HRC 58–62 (after heat treatment)
Applications: High-strength steel, stainless steel, thick plate, difficult-to-shear metals, for large hydraulic shears and heavy-duty CNC shearing machines.
Ordinary carbon steel (Q195, Q235): Choose 9CrSi or Cr12MoV for cost-effective general-purpose shearing.
Medium-low hardness steel / Al & Cu alloys (45#, 40Cr, Al, Cu): Choose SKD11 or D2 for wear resistance and long life.
Light stainless steel & medium-strength steel: Choose SKD11 or D2 for stable, clean shearing.
Thick stainless steel, high-strength alloys, hard thick materials: Choose H13 or LD for high toughness and anti-chipping performance.
Hot shearing, high-temperature working conditions: Choose H13 or H13K for heat softening resistance and thermal fatigue stability.
Hardness and toughness must be balanced: Over-hard blades chip easily; under-hard blades dull quickly. Select based on material and load.
Heat treatment directly determines performance: Premium materials require professional quenching and tempering.
For sticky materials (stainless steel, titanium, Al, Cu alloys): PreferCr12MoV or SKD11 to reduce sticking and chipping and improve cutting quality and efficiency.

Light duty, intermittent use: Regrind every 2–4 weeks
Medium daily production: Regrind every 1–2 weeks
Heavy continuous shearing: Regrind every 3–7 days
Regrind immediately once burrs, plate tearing, abnormal noise or heavy machine load occurs.
Blade clearance set too tight
Wrong blade material grade not matching cutting material
Running with dull blades for a long time
Poor blade installation, misalignment or machine vibration
Cutting material with hard impurities or uneven thickness
Thin mild steel: 9CrSi / Cr12MoV, cost-effective
Medium thickness & high hardness plate: SKD11 / D2, good wear resistance
Thick plate & heavy-duty continuous work: H13 / high alloy steel, better toughness
Keep hardness at HRC 50–55 to balance hardness and impact resistance.
