We are a professional manufacturer of hydraulic shearing machine blades, guillotine shear blades for metal plate cutting, and custom industrial hydraulic shear knives.
Materials used: 9CrSi, 6CrW2Si, Cr12MoV, H13, H13K, LD.
Key features: Rectangular cross-section, HRC 50–62 hardness, high precision, no burrs on cutting surfaces.
Customization: Available according to your drawings.
Hydraulic shearing machines use high, steady pressure—especially for thick plates—putting blades under great heat and mechanical stress.
Low-quality, surface-hardened blades often bend or break, causing costly downtime.
Our blades are designed to work well under the highest tonnages.
Swing beam shear blades: Need a specific curve or clearance.
Guillotine shear blades: Usually have 4 cutting edges that can be rotated.
Our blades meet exact OEM standards for both types.
We are a dedicated manufacturing facility.
Our blades are high-performance, easy to install, and need little maintenance.
They fit perfectly and last longer than standard blades, keeping your machines running.
9CrSi: High hardness, wear-resistant, good value; HRC 58–62; for thin cold-rolled plate, galvanized plate, aluminum, copper, plastic, leather.
6CrW2Si: Contains tungsten, heat-resistant, wear-resistant; HRC 60–62; for hot shearing, light stainless steel, medium-strength steel.
Cr12MoV / SKD-11: Wear-resistant, easy to harden; HRC 58–62; for stainless steel, silicon steel, low-carbon steel, Q235, aluminum, copper.
Cr12Mo1V1 / D2: High strength, wear-resistant, not easy to break; HRC 58–62; for stainless steel, high-strength steel, Q195/Q235/45# steel, aluminum, copper, plastic, rubber.
H13 (4Cr5MoSiV1): Heat-resistant, strong at high temperatures; HRC 50–55; for hot-sheared plates, thick plates, scrap metal, high-strength alloy steel.
LD (7Cr7Mo2V2Si): High strength, tough, wear-resistant; HRC 58–62; for high-strength steel, thick plates, hard-to-shear metals (large hydraulic shears).
Ordinary carbon steel (Q195, Q235): 9CrSi or Cr12MoV (good value)
Medium-low hardness steel, aluminum, copper (45#, 40Cr): SKD11 or D2 (long-lasting)
Light stainless steel, medium-strength steel: SKD11 or D2 (stable cutting)
Thick stainless steel, high-strength steel: H13 or LD (tough, not easy to break)
Hot shearing, high-temperature work: H13 or H13K (heat-resistant)
Balance hardness and toughness: Too hard = easy to break; too soft = easy to dull. Choose based on your material and workload.
Heat treatment matters: Good materials need professional heat treatment to work well.
Sticky materials (stainless steel, aluminum, copper): Choose Cr12MoV or SKD11 to prevent sticking and breaking.
