Good metal shearing blades make your finished parts precise and smooth-edged.
Poor or dull blades cause problems: burrs, bent metal, and extra work for your shearing machine’s hydraulic system.
Our products include: guillotine shear knives, hydraulic cutting tools, plate shearing replacement blades, steel fabrication blades.
Bent sheet edges
Lots of burrs
Damage to your shearing machine’s hydraulic system
Key Traits: Hard, resists wear, balanced, cheap, most used
Hardness: HRC 58–60 (after heat treatment)
Uses: Thin cold-rolled sheet, galvanized steel, aluminum, copper, plastic, leather
Key Traits: Tungsten/silicon mix, stays hard in heat, harder/stronger than 9CrSi, less likely to chip
Hardness: HRC 60–62 (after heat treatment)
Uses: Hot shearing, light stainless steel, medium-strength steel
Key Traits: Very wear-resistant, easy to harden, little change after heat treatment, long life
Hardness: HRC 58–60 (after heat treatment)
Uses: Low-carbon steel (all thicknesses), Q235, aluminum, copper, thin mild steel
Key Traits: Strong in heat, tough, resists heat damage, no softening or bending
Hardness: HRC 50–55 (after heat treatment)
Uses: Hot shearing (strip steel, thick plate), cold shearing (high-strength alloy, thick stainless steel)
Key Traits: High carbon/chromium, very wear-resistant, hard to bend, no chipping
Hardness: HRC 58–62 (after heat treatment)
Uses: Medium-low hardness plates (Q195/Q235/45# steel, 40Cr), aluminum, copper, brass, non-metallics (plastic, rubber, paper)
Key Traits: Strong/tough, fine grain (vanadium/molybdenum), very wear-resistant, no chipping
Hardness: HRC 58–62 (after heat treatment)
Uses: High-strength steel, thick plate, stainless steel, large hydraulic/CNC shears
Key Traits: Made from powder, super hard (HRC 62–65+), very wear-resistant, steady performance
Uses: High-precision shearing, heavy-duty/high-frequency jobs (needs long life)
Flatness Control: Straightness error ≤ 0.02mm (even for long blades) – done with precision grinding
Optimal Clearance: Right gap reduces heat, makes smooth cuts, no extra polishing needed
General carbon steel (Q195, Q235): 9CrSi or Cr12MoV (cheap, reliable)
Medium-low hardness steel, aluminum/copper (45#, 40Cr, brass): SKD11 or D2 (wear-resistant, long life)
Light stainless steel, medium-strength steel: SKD11 or D2 (balances wear resistance and anti-chipping)
Thick stainless steel, high-strength alloys: H13 or LD (tough, no breaking)
Hot shearing (strip steel, thick plate): H13 or H13K (resists heat softening)
High-precision, heavy-duty shearing: Powder metallurgy (ASP23/ASP60) (longest life, best precision)
Rotate Blades: Most blades have 2–4 cutting edges. Flip them often to double their use.
Adjust Clearance: Change the blade gap based on sheet thickness to avoid chipping.
Lubricate Blades: Proper lubrication cuts wear by 15% and keeps blades sharp.
Harder is not better: Balance hardness and toughness. Too hard = chipping; too soft = dulling.
Heat treatment matters: Even good materials need professional quenching/tempering to work well.
Sticky materials (stainless steel, aluminum, copper): Use Cr12MoV or SKD11 to prevent sticking/chipping.

1. Blanking-choose materials according to customer requirements.
2. Forging-Forging is mainly to increase the density of the material.
3 .Annealing-to lower the temperature for processing.
4 .Finishing ---- mainly processing materials.
5 .Inspection ---- Inspect whether the product is consistent with the drawing sample.
6.Quenching ---- Improve the hardness of molded products and materials.
7 .Annealing-In order to increase the wear resistance of the product, it must be annealed for a long time to prevent the blade from breaking
8 .Tempering-mainly the parallelism of the tempering products for processing.
9 .Rough grinding ---- rough grinding the surface of the product.
10.Precision grinding ---- Super-precision grinding and mirror grinding to improve the accuracy and parallelism of the product.
11. Inspection-Let unqualified products refuse to flow into the market.
12 .Packing ---- Pack differently according to different products.
