Guillotine shear blades for metal plate cutting
Custom industrial hydraulic shear knives
Replacement blades for mobile hydraulic shears (excavators)
Materials: 9CrSi, 6CrW2Si, Cr12MoV, H13, H13K, LD
Shape: Rectangular cross-section
Hardness: HRC50–62
Quality: Precision cuts (no burrs, no crooked edges), good edge retention
Customization: Available per your drawings
9CrSi (Alloy Tool Steel): Hard, wear-resistant, cost-effective. Cuts thin cold-rolled plate, galvanized plate, aluminum, copper, and non-metals (plastic, leather).
6CrW2Si (Alloy Tool Steel): Has tungsten, stays hard at high temps. Good for hot cutting, light stainless steel, and medium-strength steel.
Cr12MoV/SKD-11 (High Carbon High Chromium Steel): Wear-resistant, hardens well. Cuts stainless steel, silicon steel, high-strength steel, Q235, aluminum, and copper.
H13 (4Cr5MoSiV1) (Hot Work Die Steel): Handles high temps well. Good for hot-rolled plate, thick plate, scrap metal, and thick stainless steel.
Cr12Mo1V1/D2 (High Carbon High Chromium Steel): Strong, wear-resistant. Cuts medium/low-hardness steel, aluminum, copper, and non-metals (plastic, rubber).
LD (7Cr7Mo2V2Si) (Cold Work Die Steel): Tough, wear-resistant. Cuts high-strength steel, thick plate, and hard-to-cut metals (for large hydraulic/CNC shears).
Traits: Hard, wear-resistant, balanced performance, cost-effective (most widely used). Good edge retention; fewer burrs and crooked edges.
Hardness: HRC 58–60 (after heat treatment)
Best for: Thin cold-rolled plate, galvanized plate, aluminum, copper, plastic, leather
Traits: Has tungsten/silicon; stays hard at high temps. Stronger than 9CrSi; better toughness. Good edge retention; no burrs/crooked edges in hot cutting.
Hardness: HRC 60–62 (after heat treatment)
Best for: Hot cutting, light stainless steel, medium-strength steel
Traits: Wear-resistant, hardens well, long life. Great edge retention; smooth cuts (no burrs/crooked edges).
Hardness: HRC 58–60 (after heat treatment)
Best for: All thicknesses of low-carbon steel, Q235, aluminum, copper
Traits: Handles high temps well; tough, no softening/deformation. Good edge retention; no burrs/crooked edges in hot cutting.
Hardness: HRC 50–55 (after heat treatment)
Best for: Hot-rolled plate, thick plate, high-strength alloy steel, thick stainless steel
Traits: Very wear-resistant, hard; resists deformation. Excellent edge retention; few burrs/crooked edges for metals and non-metals.
Hardness: HRC 58–62 (after heat treatment)
Best for: Medium/low-hardness steel, aluminum, copper, plastic, rubber, composite materials
Traits: Strong, tough; has vanadium/molybdenum for fine grain. Great wear resistance and edge retention; no burrs/crooked edges on hard-to-cut materials.
Hardness: HRC 58–62 (after heat treatment)
Best for: High-strength steel, thick plate, stainless steel, large hydraulic/CNC shears
Ordinary carbon steel (Q195, Q235): Choose 9CrSi or Cr12MoV (cost-effective, meets basic needs).
Medium/low-hardness steel, aluminum/copper: Choose SKD11 or D2 (wear-resistant, long life).
Light stainless steel, medium-strength steel: Choose SKD11 or D2 (stable performance).
Thick stainless steel, high-strength steel: Choose H13 or LD (tough, resists chipping).
Hot cutting (strip steel, thick plate): Choose H13 or H13K (heat-resistant, no softening).
Hardness isn’t everything: Too hard = easy chipping; too soft = dulls fast. Both cause poor edge retention, burrs, and crooked edges. Choose based on your material and load.
Heat treatment matters: Good materials need professional quenching/tempering to work well.
Sticky materials (stainless steel, aluminum, copper): Choose Cr12MoV or SKD11 to prevent sticking, chipping, and poor cuts.

A: We use high-grade industrial tool steels to ensure maximum longevity. The most common materials include:
9CrSi: Thin cold-rolled plate, galvanized plate, aluminum, copper
6CrW2Si: Hot cutting, light stainless steel, medium-strength steel.
Cr12MoV1 (D2): Medium/low-hardness steel, aluminum, copper, plastic, rubber, composite materials.
H13: Hot-rolled plate, thick plate, high-strength alloy steel, thick stainless steel.
A: This depends on your material type and volume. However, you should inspect your blades if you notice:
Increased Burrs: The edge of the metal is no longer clean.
Machine Noise: The shear makes a louder "thud" rather than a "snip" sound.
Visible Wear: Rounded edges or small chips on the blade.
Pro Tip: Most of our blades are 4-edge blades, meaning you can rotate them four times before needing a professional regrind.
A: As a general rule of thumb, the blade clearance should be approximately 5% to 10% of the material thickness.
Thin Materials: Require a tighter gap to prevent the sheet from "folding" between the blades.
Thick Materials: Require a larger gap to reduce tonnage and prevent blade chipping.
Note: Always refer to your machine manufacturer’s manual for specific settings.
A: Yes! We manufacture replacement blades for all major brands, including Amada, LVD, Accurpress, Cincinnati, Pearson, Edwards, and Gasparini. If you have a unique or older machine, simply provide us with a technical drawing or the dimensions (Length x Width x Thickness) and bolt-hole patterns.
A: To maximize tool life, follow these three steps:
Never shear hardened steel: Only cut materials within the blade's rated hardness.
Maintain Clearance: An incorrect gap is the #1 cause of chipped edges.
Keep it Clean: Ensure the metal sheet is free of heavy scale, rust, or debris that can cause uneven pressure.
A: Since these are precision tools, we take extra care. Our blades are coated in anti-rust oil, wrapped in protective film, and secured in heavy-duty reinforced wooden crates to ensure they arrive flat and sharp.
