Heavy-Duty Mobile Scrap Shear Blades

1. Product Range & Applications

ALAS Machinery manufactures direct-replacement and custom OEM mobile scrap shear blades for excavator hydraulic attachments. These industrial blades cut HMS 1 & 2, structural steel profiles, rebar, steel pipes, and automotive scrap.

• Manufacturing Background: 15+ years engineering heavy machinery wear parts.

• Supply Options: Production via OEM part numbers or custom fabrication from technical blueprints.

3. Engineering Advantages

• Virgin Tool Steel: Produced from 100% virgin tool steel billets. No recycled scrap metal fillers used, reducing premature fracturing risks.

• Vacuum Quenching: Computer-controlled integral vacuum heat treatment ensures consistent hardness from the blade surface to the core, avoiding the soft spots common in flame hardening.

• CNC Machining: Precision ground tolerances ensure correct blade clearance settings, minimizing excavator hydraulic system backpressure.

• Indexable Profiles: Rectangular configurations feature 2-edge or 4-edge reversible designs for multi-cycle on-site rotation.

4. OEM Fitment & Compatibility

Blades match original OEM installation dimensions, bolt hole centerlines, and clearance tolerances:

• Genesis Series: Direct-fit for Genesis GXP, GXT, and GMS attachments.

• Labounty Series: Fits LaBounty MSD series shears, including MSD 1500, MSD 2000, MSD 2500, and MSD 3000.

• European Series: Fits Mantovanibenne, Verachtert, and European specification attachments.

• Full Kits Available: Main cutting edges supplied with matching piercing tips, guide blades, mounting fasteners, and adjustment shims.

5. Quality Control (QC) Protocol

1. Material Validation: 100% spectroscopy testing of raw steel chemical composition against standard grade specifications.

2. Ultrasonic Inspection: Non-destructive testing (NDT) of blade blanks to eliminate internal micro-cracks or gas porosity.

3. Hardness Profile Verification: Multi-point Rockwell (HRC) testing across the cutting edge and core post-tempering.

4. Dimensional Audit: 100% verification of mounting hole spacing, counterbore depths, thickness, and edge angles.

6. Customization & Ordering Workflow

1. Input Requirements: Provide OEM part numbers, attachment model, or a technical drawing (Length × Width × Thickness + Hole Pattern).

2. Material Selection: Steel grade matched to customer jaw pressure and typical scrap material input.

3. Engineering Sign-off: Technical drawing approval and commercial quote issued within 24 hours.

4. Machining: Production carried out strictly to approved print tolerances.

7. Packaging & Shipping Specifications

• Rust Prevention: All ground steel surfaces are coated with industrial anti-rust oil and wrapped in moisture-proof plastic film before boxing.

• Export Packaging: Shipped in heavy-duty, ISPM 15 compliant fumigated wooden cases with internal structural bracing to prevent movement during sea freight.

• Logistics Ready: Supports LCL and FCL export shipments with clear lifting indicators and metal banding reinforcement.

8. Technical FAQ

Q1: What steel materials are stocked for mobile shear blades?

A: Standard inventory includes H13, 6CrW2Si, D2, X45 (1.2767), and 1.2746. Custom alloy configurations are available for specific impact or wear requirements.

Q2: Which material grade is recommended for heavy structural steel and vehicle dismantling?

A: H13 and 1.2746. Both grades provide the impact toughness required to resist shock-loading and edge-fracturing under high hydraulic pressure.

Q3: What are the application limits for 6CrW2Si blades?

A: 6CrW2Si fits medium-duty scrap processing (rebar, common steel pipes, mixed yard waste). It balances shock resistance and wear life under moderate mechanical impact.

Q4: When should D2 steel blades be deployed?

A: Deploy D2 strictly for light, thin, highly abrasive scrap metal. It is not recommended for thick structural beams due to high chipping risks under deflection.

Q5: Why is X45 (1.2767) specified for European demolition attachments?

A: 1.2767 contains high Nickel (Ni) content for extreme structural core toughness, meeting the direct OEM alternative standard for European heavy demolition attachments.

Q6: How is the final hardness of the shear blades calibrated?

A: Hardness is matched to the material grade and application (e.g., H13 at 48–54 HRC; 1.2746 at 52–56 HRC). This targets the optimal balance between continuous edge retention and fracture prevention.

Q7: Are these shear blades rotatable?

A: Yes. Rectangular blade designs are indexable with 2 or 4 usable cutting edges, allowing rotation to fresh sides before regrinding is required.

Q8: Do you supply individual blades or full sets?

A: Both. We supply main cutting edges individually or as full maintenance kits with compatible guide blades, piercing tips, and alignment shims.
