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 |
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 |
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) |
Characteristics: Excellent high temperature strength, impact toughness and thermal fatigue resistance, can maintain good hardness and shearing performance in high temperature environment, not easy to soften and deform;
Hardness: HRC 50-55 (after heat treatment);
Applicable to: Hot shearing strip steel, hot shearing thick plate, cold shearing high strength alloy steel and stainless steel thick plate.
Performance: An upgraded and modified version of H13, retaining the excellent impact resistance of H13 while improving core toughness, high-temperature stability, and fatigue resistance. Hardenability is superior to conventional H13;
Suitable for ≥180T ultra-large tonnage alligator shears, primarily for shearing extra-thick steel plates (≥40mm), heavy alloy steel materials, thick-walled seamless pipes, large structural steel, and other ultra-high pressure and high-impact materials, as well as ultra-heavy continuous shearing operations in scrap metal yards;
Advantages: More resistant to strong impact and fatigue than conventional H13, with a 20%-30% longer service life than H13 under ultra-heavy working conditions, making it the preferred material for ultra-large alligator shears.
Characteristics: A high-performance cold work die steel with high strength and excellent toughness. Its contained V (vanadium) and Mo (molybdenum) significantly refine the grain, giving it extremely high bending strength and toughness, better wear resistance, and extremely strong chipping resistance;
Hardness: HRC 58-62 (after heat treatment);
Applicable to: Shearing high strength steel, thick plate, stainless steel and various hard-to-shear metal materials, commonly used for blades of large hydraulic shearing machines and heavy CNC shearing machines.
The performance of the four materials depends on precise heat treatment and surface strengthening. Differences in processing can lead to more than a 2-fold difference in blade service life for the same material.
1. Vacuum heat treatment is used instead of ordinary air quenching to reduce surface oxidation and decarburization of the blade, ensuring overall hardness uniformity;
2. Low-temperature tempering at 180-220℃ is performed immediately after quenching to eliminate internal stress, prevent blade deformation and cracking, and stabilize the core hardness and toughness of the material.
