2. Steel Grade & Hardness Specification Matrix

3. Manufacturing Specifications

100% Virgin Billets: Produced using pure, non-recycled tool steel. This prevents internal voids and chemical variances that cause brittle failure under high hydraulic tonnage.

Vacuum Furnace Quenching: Fully automated heat treatment delivers consistent Rockwell hardness from the blade surface to the core. No soft spots.

CNC Grinding: All critical fitment dimensions, countersinks, and bolt holes are finished on CNC grinding machines. Machining tolerances are maintained within ±0.02mm to limit host machine backpressure.

Indexable Cutting Edges: Symmetrical geometries allow multi-sided field rotation, increasing the service life per blade set.

4. Inspection & Export Packaging

Four-Stage Quality Control Protocol:

Chemical Testing: Spectrometer verification of elemental ratios against mill test certificates.

Hardness Measurement: Multi-point HRC testing on both face and core sections.

Dimensional Inspection: 100% validation of coordinates and hole-spacing using digital calipers and CMM.

Internal Defect Scanning: Ultrasonic non-destructive testing (NDT) to verify zero internal micro-cracks.

Packaging Standard:

Rust Prevention: Coated with anti-rust oil and sealed in vapor corrosion inhibitor (VCI) plastic film.

Securing: Reinforced with heavy-duty edge guards to prevent shifting during transit.

Shipping Box: Packed into ISPM 15 standard fumigated wooden cases, banded for ocean freight and forklift handling.

5. Technical FAQ

Q: How do I select the steel grade and HRC for my application?

A: Selection depends on scrap thickness. For high-impact, thick structural steel cutting, choose H13 (48-54 HRC) or X45 (50-55 HRC) to absorb impact energy without cracking. For high-abrasion, continuous shearing of thin sheet scrap, choose D2 (56-60 HRC) for maximum edge wear life.

Q: What is the benefit of virgin steel billets over recycled materials?

A: Recycled steel contains trace impurities and micro-voids. Under extreme hydraulic shear forces, these imperfections act as stress focal points, causing sudden blade fractures or chipping. Virgin tool steel guarantees uniform chemistry and structure to handle full attachment tonnage.

Q: What prevents your blades from cracking during field operations?

A: We use Vacuum Furnace Quenching to eliminate the uneven hardness (soft spots or over-brittle zones) common in standard flame heat treatment. Combined with CNC ground flatness within ±0.02mm, this eliminates internal structural stress and uneven wear.

Q: Are these blades 100% interchangeable with original OEM parts?

A: Yes. All dimensions, bolt holes, and clearances are machined to standard OEM coordinates for series like the LaBounty MSD and Genesis GXP/GXT. They bolt directly into the factory attachment seats without modification.
