  • Cross Blade

  • Lower Secondary Blade

  • Lower Primary Blade

3. Basic Blade Info

  • Materials: 9CrSi, 6CrW2Si, Cr12MoV, H13, H13K, LD

  • Shape: Rectangular cross-section

  • Hardness: HRC50–62

  • Quality: Precise cuts, no burrs

  • Customization: Available by your drawings

4. Common Blade Materials

  • H13 (4Cr5MoSiV1)Type: Hot Work Die Steel

  • Key Features: Good high-temperature strength and fatigue resistance

  • What It Cuts: Hot-rolled plate, iron plate, scrap metal, stainless steel thick plate

  • LD (7Cr7Mo2V2Si)Type: Cold Work Die Steel

  • Key Features: Strong, tough, wear-resistant, not easy to chip

  • What It Cuts: High-strength steel, stainless steel, thick plate, hard-to-cut metals

5. Detailed Material Performance

H13 (4Cr5MoSiV1)

  • Hardness: HRC52–55 after heat treatment

  • Features: Resists impact and high temperature, tough core

  • Use for: ≥160T alligator shears; cuts ultra-thick steel (≥30mm), alloy steel, thick pipes

  • Pros: Good for heavy impact, no chipping/breakage, easy to use

H13K (Modified H13)

  • Features: Better than H13; tougher, more stable at high temperatures

  • Use for: ≥180T large alligator shears; cuts extra-thick steel (≥40mm), heavy alloy steel, large structural steel

  • Pros: More durable than H13; 20–30% longer service life

LD Steel (7Cr7Mo2V2Si)

  • Hardness: HRC60–64 after heat treatment

  • Features: Very wear-resistant, uniform hardness

  • Use for: 100T–160T alligator shears; cuts 10–30mm steel, rebar, rusty scrap

  • Pros: Most wear-resistant; fewer replacements, higher efficiency

6. Strengthening Process

Good processing makes blades last twice as long. Key steps:
  • Vacuum heat treatment: No surface oxidation; uniform hardness

  • Low-temperature tempering (180–220℃): Reduces internal stress; prevents deformation/cracking

7. How to Choose Material

  • Common choice: H13 (for crocodile/shear blades)

  • Complex scrap: Choose H13K

  • Higher requirements: Contact us for material upgrades

8. Our Advantages

  • We don’t just sell replacements — we improve performance

  • Optimize blades for your machine (mobile/stationary) to lower costs

  • Precision blades: Less vibration, fewer replacements, more profit

  • Tough design: Cuts hard scrap without breaking (hard outer layer, tough core)

9. Heavy-Duty Blade Highlights

  • Resists impact: No chipping/cracking when cutting thick beams/pipes

  • Fits most machines:            Perfect bolt holes: Easy to install

  • Precise alignment: Clean cuts even on thin/bundled scrap

  • Saves money: Reduces machine wear; lower cost per ton of scrap
