Finding a Reliable Sheet Metal Shear Blades Supplier: Quality Beyond the Edge
In the competitive world of metal fabrication, your choice of a Sheet Metal Shear Blades Supplier directly impacts your production cost and edge quality. Low-grade blades lead to frequent sharpening, burred edges, and unexpected downtime. At ALAS Machinery, we understand that a shear blade isn’t just a piece of steel — it’s the heart of your shearing efficiency.
Why Metallurgy is the Foundation of a Good Supplier
As a dedicated manufacturer, we don’t compromise on materials. Most “trading” suppliers offer generic carbon steel. ALAS Machinery provides engineered blade materials matched to your shearing application, with strict control over composition, hardness, and heat treatment.
We specialize in the production of:
Shearing machine blades
Hydraulic shearing blades
Guillotine shear blades for metal plate cutting
Industrial hydraulic shear knives customization
Replacement blades for mobile hydraulic shears and excavators
Heavy-duty scrap shear blades for metal recycling
ALAS blades are typically made from premium materials such as 9CrSi, 6CrW2Si, Cr12MoV, H13, H13K, and LD. Our blades feature a stable rectangular cross-section and controlled hardness ranging from HRC50 to HRC62, ensuring high-precision, burr-free cutting surfaces. Full customization according to customer drawings is always available.
Common Material Overview of Metal Shear Blades
9CrSi – Alloy Tool Steel
High hardness, excellent wear resistance, minimal quenching deformation, and outstanding cost performance. Ideal for thin cold-rolled plate, galvanized plate, aluminum plate, copper plate, and non-metallic materials including plastic and leather.
6CrW2Si – Alloy Tool Steel
Contains tungsten for exceptional red hardness and wear resistance. Suitable for hot shearing operations, light stainless steel, and medium-strength steel.
Cr12MoV / SKD-11 – High Carbon High Chromium Steel
Excellent wear resistance and hardenability, long service life, and stable performance under impact. Widely used for stainless steel, silicon steel, high-strength steel, various thicknesses of low-carbon steel, Q235, aluminum, and copper plates.
H13 (4Cr5MoSiV1) – Hot Work Die Steel
Superior high-temperature strength and thermal fatigue resistance. Performs reliably in hot shearing of hot-rolled plate, iron plate, medium and thick plate, scrap metal, hot-sheared strip steel, and cold shearing of high-strength alloy steel and thick stainless steel.
Cr12Mo1V1 / D2 – High Carbon High Chromium Steel
High strength, excellent wear resistance, and outstanding chipping resistance. Applied for shearing medium and low-hardness plates such as Q195, Q235, 45# steel, 40Cr, aluminum, copper, brass, red copper, as well as non-metallic and composite materials.
LD (7Cr7Mo2V2Si) – Cold Work Die Steel
High strength, excellent toughness, wear resistance, and chipping resistance. Designed for high-strength steel, stainless steel, thick plates, and difficult-to-shear metals, commonly used in large hydraulic shearing machines and heavy CNC shearing machines.
Powder Metallurgy Steel – High-End Alloy Tool Steel
Ultra-high hardness, uniform structure, and extremely long service life. Used for high-end composite plate, wear-resistant steel, and precision shearing applications with strict requirements for durability.

Simple Guide for Blade Material Selection
Shearing ordinary carbon steel (Q195, Q235): Choose 9CrSi or Cr12MoV for cost-effective general shearing.
Medium-low hardness steel, aluminum, copper (45#, 40Cr, brass): Select SKD11 or D2.
Light stainless steel and medium-strength steel: Use SKD11 or D2.
Thick stainless steel, high-strength alloy steel: Choose H13 or LD.
Hot shearing and high-temperature working conditions: Use H13 and H13K.
High-end precision and long service life requirements: Select powder metallurgy steel (ASP23 / ASP60).
Important Notes
Higher hardness is not always better. A balance between hardness and toughness is critical: overly hard blades chip easily, while soft blades dull quickly. Selection must match your shearing material and load.
For the same material, heat treatment directly determines performance. High-quality alloy steels require professional quenching and tempering to achieve optimal wear resistance and toughness.
For sticky materials such as stainless steel, titanium alloy, aluminum, copper, and their alloys, we recommend D2 to prevent adhesion and chipping, improving cutting efficiency and surface quality.
