In the modern metal fabrication industry, the efficiency of your shearing process is defined by the quality of your cutting tools. Hydraulic metal shear blades are the core components that handle the immense pressure of hydraulic systems to deliver clean, accurate cuts. Choosing high-quality hydraulic shear blades is essential for maintaining productivity and reducing the mechanical strain on your heavy-duty machinery.
Unlike manual shears, hydraulic metal shear blades must withstand consistent, high-tonnage force without deforming. Our blades are manufactured from premium shock-resistant tool steels, such as H13，LD or H13K. These materials undergo a specialized vacuum heat treatment process to ensure that each hydraulic shear blade possesses the necessary toughness to slice through thick steel plates and stainless steel sheets with ease.
A dull hydraulic metal shear blade can lead to material burrs and increased energy consumption. Our precision-ground hydraulic shear blades are designed with optimized rake angles and clearances to ensure a smooth shearing action. This precision reduces the "shock" to the hydraulic cylinders, extending the life of your entire machine while providing a professional, burr-free finish on every workpiece.
We understand that different hydraulic shears require specific blade geometries. Beyond our standard hydraulic metal shear blades, we offer custom manufacturing tailored to your machine's brand and specific material thickness requirements. Our hydraulic shear blades are engineered for easy installation and perfect alignment, ensuring your facility experiences minimal downtime during blade rotations.
superior hydraulic metal shear blades is a direct investment in your facility's operational success. Our high-performance hydraulic shear blades provide the reliability, precision, and durability required to stay competitive in the high-demand metalworking market.

ALAS blades are typically made from materials such as 9CrSi, 6CrW2Si, Cr12MoV, H13, H13K, and LD. The blades have a rectangular cross-section and a hardness of HRC50 to 62. They provide high-precision, burr-free cutting surfaces. Customization according to drawings is available.
The following table summarizes the type, core characteristics and main applicable shearing materials of common blade materials:
Blade Material | Material Type | Characteristics | Main Shearing Materials |
9CrSi | Alloy Tool Steel | High hardness, high wear resistance, small quenching deformation, high cost performance | Thin cold-rolled plate, galvanized plate, aluminum plate, copper plate; non-metallic materials such as plastic and leather |
6CrW2Si | Alloy Tool Steel | Contains tungsten element, excellent red hardness and wear resistance | Hot shearing operations materials, light stainless steel, medium strength steel |
Cr12MoV/SKD-11 | High Carbon High Chromium Steel | Excellent wear resistance and hardenability | Stainless steel, silicon steel, high strength steel, low carbon steel of various thicknesses, Q235, aluminum plate, copper plate |
H13 (4Cr5MoSiV1) | Hot Work Die Steel | Excellent high temperature strength and thermal fatigue resistance | Hot-sheared hot rolled plate, iron plate, medium and thick plate, scrap metal, hot-sheared strip steel, cold-sheared high strength alloy steel, stainless steel thick plate |
Cr12Mo1V1/ D2 | High Carbon High Chromium Steel | High strength, good wear resistance, excellent chipping resistance | Stainless steel, high strength steel, silicon steel, medium and low hardness plates (Q195/Q235/45# steel / 40Cr, etc.), aluminum / copper / brass / red copper plate; non-metallic materials such as plastic / rubber / paper / fiberboard, composite materials |
LD (7Cr7Mo2V2Si) | Cold Work Die Steel | High strength, good toughness, wear resistance and chipping resistance, excellent comprehensive performance | High strength steel, stainless steel, thick plate and hard-to-shear metal materials (for large hydraulic shearing machines, heavy CNC shearing machines) |
Powder Metallurgy Steel | High-end Alloy Tool Steel | Ultra-high hardness, extremely long service life | High-end composite plate, wear-resistant steel, high-end precision shearing metal materials (for high wear resistance and long service life requirements) |
Characteristics: High hardness, excellent wear resistance, medium toughness, balanced comprehensive performance, high cost performance, and the most widely used material;

Applicable to: High-end precision shearing operations and working conditions with extremely high requirements for wear resistance and service life.
Higher blade hardness is not always better, and hardness and toughness need to be balanced: Excessively high hardness is prone to chipping, while excessively low hardness is prone to passivation. It is necessary to select reasonably according to the shearing material and operation load;
For the same material, the heat treatment process directly affects the performance: High-quality materials need to be matched with professional quenching and tempering processes to give full play to their advantages such as wear resistance and toughness;
For sticky knife materials (such as Stainless steel, titanium alloy, aluminum, copper and its alloys): Prioritize Cr12MoV and SKD11, which can effectively prevent knife sticking and chipping, and improve shearing efficiency and quality.
