How to Choose the Right Guillotine Shear Blades for Longer Life
In metal fabrication, your cut quality depends on your blade. Guillotine shear blades are key to your machine. Picking the right material and maintaining them well cuts costs and downtime.
Our Products

Common Blade Materials Overview
Below are common blade materials, their key traits, and what they cut best:
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).
Detailed Blade Material Traits
9CrSi Alloy Tool Steel
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
6CrW2Si Alloy Tool Steel
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
Cr12MoV / SKD11 High Carbon High Chromium 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
H13 (4Cr5MoSiV1) Hot Work Die Steel
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
D2 (American Standard)
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
LD (7Cr7Mo2V2Si) Cold Work Die Steel
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
Blade Material Selection Guide
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).
Important Notes
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.
