Guillotine Shearing Blade

Shearing Machine Blades Manufacturer

Guillotine Shearing Blades: Precision Tools for Metal Fabrication

Advanced Manufacturing Process

• Material Choice: We offer 9CrSi, 6CrW2Si, Cr12MoV, H13, H13K, and LD. Choose the right one for your cutting thickness and material type.

• Full-Length Heat Treatment: Our blades go through full-length vacuum heat treatment, with even hardness (HRC 50-62, up to 64 HRC for special grades) to last longer.

• CNC Precision Grinding: Critical surfaces are ground to tiny tolerances for perfect fit and parallelism, ensuring precise cuts even for long blades.

Our Products

• Guillotine shear blades for metal plate cutting

• Custom industrial hydraulic shear knives

• Replacement blades for mobile hydraulic shears (excavators)

• ALAS blades: made of premium materials, rectangular cross-section, burr-free cuts, custom sizes per your drawings

Common Blade Materials & Uses

1. 9CrSi (Alloy Tool Steel)

• Features: High hardness, wear-resistant, low deformation, good value

• Cuts: Thin cold-rolled sheet, galvanized sheet, aluminum, copper, plastic, leather

• Lengths: 2500mm, 3200mm, 4100mm, custom

2. 6CrW2Si (Alloy Tool Steel)

• Features: Contains tungsten, stays hard at high temperatures, wear-resistant

• Cuts: Hot-sheared materials, light stainless steel, medium-strength steel

• Lengths: 2500mm, 3200mm, 4100mm, custom

3. Cr12MoV / SKD-11 (High Carbon High Chromium Steel)

• Features: Very wear-resistant, easy to harden

• Cuts: Stainless steel, silicon steel, high-strength steel, Q235, aluminum, copper

• Lengths: 2500mm, 3200mm, 4100mm, custom

4. H13 (4Cr5MoSiV1) (Hot Work Die Steel)

• Features: Strong at high temperatures, resists fatigue from heat

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

• Lengths: 2500mm, 3200mm, 4100mm, custom

5. Cr12Mo1V1 / D2 (High Carbon High Chromium Steel)

• Features: High strength, wear-resistant, not easy to chip

• Cuts: Stainless steel, high-strength steel, Q195/Q235/45# steel, aluminum, copper, plastic, rubber

• Lengths: 2500mm, 3200mm, 4100mm, custom

6. LD (7Cr7Mo2V2Si) (Cold Work Die Steel)

• Features: High strength, tough, wear-resistant, good overall performance

• Cuts: High-strength steel, thick plate, stainless steel, hard-to-cut metals (for large hydraulic shears)

• Lengths: 2500mm, 3200mm, 4100mm, custom

Material Selection Guide

• Ordinary carbon steel (Q195, Q235): Choose 9CrSi or Cr12MoV (good value, all lengths available)

• Medium/low-hardness steel, aluminum, copper: Choose SKD11 or D2 (wear-resistant, long service life)

• Light stainless steel, medium-strength steel: Choose SKD11 or D2 (stable cutting performance)

• Thick stainless steel, high-strength steel: Choose H13 or LD (tough, not easy to chip)

• Hot shearing, high-temperature work: Choose H13 or H13K (resists high temperatures)

Important Notes

• Balance hardness and toughness: Too hard = easy to chip; too soft = easy to dull. Choose based on your cutting material and load.

• Heat treatment matters: Good materials need professional heat treatment to work well, especially for long blades.

• Sticky materials (stainless steel, aluminum, copper): Choose Cr12MoV or SKD11 to prevent sticking and chipping.
