Common Material Overview & High-Performance Solutions for Hydraulic Scrap Metal Shear Blades
In tough metal recycling yards, hydraulic scrap metal shear blades are key parts for cutting I-beams, heavy rebar, old vehicles, and other scrap metal. Blade quality affects how fast you work, how often equipment stops, and your overall costs. Below is a simple guide to common blade materials and the benefits of Alas Machinery’s high-performance blades. We are a technical tooling brand—not just a supplier—focused on solving your shearing problems with professional engineering help.
Common Scrap Metal Shear Blade Materials
This section covers the main types of blade materials, their key features, and what they cut best. With material-specific recommendations from Alas Machinery, you’ll pick the right blade to reduce chipping and breakage and extend blade life.
H13 (4Cr5MoSiV1) Hot Work Die Steel
Material Type: Hot work die steel
Key Features: Strong at high temperatures, tough, and resists damage from heat. Stays hard and works well in hot conditions—won’t soften or bend easily.
Hardness: HRC 50–55 (after heat treatment)
What It Cuts: Hot-rolled plates, iron plates, medium-thick plates, scrap metal, hot-cut strip steel. Also cuts high-strength alloy steel and thick stainless steel when cold.
LD (7Cr7Mo2V2Si) Cold Work Die Steel
Material Type: High-performance cold work die steel
Key Features: Strong, tough, wear-resistant, and hard to chip. Elements like vanadium and molybdenum make it strong and flexible, with great overall performance.
Hardness: HRC 58–62 (after heat treatment)
What It Cuts: High-strength steel, stainless steel, thick plates, and hard-to-cut metals. Often used for large hydraulic shears and heavy CNC shears.
High-Performance Hydraulic Scrap Metal Shear Blades (Alas Machinery)
In busy recycling yards, your equipment’s performance depends on its blades. Hydraulic shear blades cut I-beams, heavy rebar, and old vehicles. Cheap blades chip often, stop equipment, and cost more. Alas Machinery makes precision-forged blades for tough shearing tasks—backed by Alas technical support to keep your work running smoothly.
Why Toughness Matters (Material Science)
Shearing scrap metal uses huge force, and metal hardness can be unpredictable. To avoid blade failure, we use special alloy steels. Our material-specific recommendations match your needs to reduce chipping and breakage:
H13 (SKD-61): Our top choice for heavy work. Balances heat resistance and toughness—perfect for non-stop use in alligator and container shears.
Custom Alloys: Special materials for tough jobs (e.g., high-tensile steel, dirty scrap).
Benefits of Forged Steel & Vacuum Heat Treatment
All our blades start as high-density forged steel—eliminates gaps inside and aligns metal grains for maximum strength.
After machining, blades go through vacuum heat treatment to reach HRC 52–56 hardness.
This hardness is perfect: hard enough for clean cuts, but flexible enough to handle shocks without breaking.
All designed to minimize downtime through engineering—not just a basic product.
Fits Machines Worldwide
We make replacement blades that fit 100% of machines, including Lefort, Genesis, LaBounty, and local Chinese models. Our CNC grinding ensures:
Tight Tolerances: Upper and lower blades line up perfectly to avoid jams.
Multiple Cutting Edges: Most rectangular blades have 4 usable edges—rotate them to make blades last 4x longer.
Smooth Surface: Reduces friction and heat during fast recycling work.
Alas Technical Support: More Than Just Blades
As a technical tooling brand, we’re not a basic supplier—we offer full support to solve your hardest shearing problems:
Material-Specific Recommendations: Our team looks at your materials, work conditions, and equipment to pick the best blade. Reduces chipping, breakage, and how often you replace blades.
Engineering Support for Complex Jobs: For tough tasks (e.g., high-tensile scrap, odd-shaped metal), our engineers create custom solutions for smooth, efficient work.
Minimize Downtime Through Engineering: We help with material choice, blade design, installation, and maintenance to reduce equipment stops and boost efficiency.
