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.

Common Material Overview of Scrap Shear Blades

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)

Detailed Characteristics of Various Blade Materials

H13 (4Cr5MoSiV1) Hot Work Die Steel

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.

LD (7Cr7Mo2V2Si) Cold Work Die Steel

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.

Mechanical blades are (special wearing parts) due to different cutting products, correct and reasonable selection of materials, heat treatment hardness, grinding accuracy, packaging requirements. Please contact us before purchase and confirm whether the blade specifications materials you need are available goods.

^{Our quality: All mechanical parts, tools, and molds are manufactured in-house. Upon arrival at our warehouse, products undergo rigorous inspection by a dedicated quality control department. The following is our production process:}        

<sup>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.</sup>
