A.   Structural Design Advantages

1. Optimized Cutting Geometry

- The half-arrow profile provides a 30°–45° front cutting angle for smoother soil or gravel penetration and lower initial resistance.

- Easier penetration than flat edges

- Reduced fuel consumption and load

- Improved efficiency and smooth operation

2. Balanced Thickness and High Impact Resistance

The tapered design distributes stress evenly, enduring heavy impact and bending without cracking or deformation.

3. Compatible with Welding or Bolted Installation

The flat base allows both welding and bolting for easy maintenance and replacement.

B.   Material and Wear Resistance Advantages

1. Made from High-Strength Wear-Resistant Steel

Manufactured from FGNM or FG500 steel with hardness up to 460–520HB, providing excellent strength and toughness.

2. Optional Reinforcement Technologies

- Tungsten Carbide Grit Hardfacing for extra surface wear protection;
- Brazed Tungsten Carbide Inserts for 2–5× longer service life;
- Shot Blasting & Stress Relief Treatment to enhance bonding and fatigue resistance.

3. Stable Wear Pattern

The half-arrow edge wears gradually, maintaining an effective cutting angle without early dulling.

C.   Application Performance

Earthmoving: smooth penetration, less resistance

Mining/Quarrying: strong impact & wear balance

Frozen or sandy ground: smooth cutting, even wear

Heavy-duty operation: 30–100% longer lifespan

D.   Economic and Maintenance Benefits

1. Extended Life of Base Edge and Bucket

Absorbs most of the wear, protecting the base structure and extending its life 1–3×.

2. Lower Total Operating Cost

Though the initial cost is higher, reduced replacement and downtime lower overall cost.

3. Reduced Downtime and Easy Maintenance

Quick installation or replacement, especially with bolt-on design, ensures higher machine availability.

E.   Overall Conclusion

The Half Arrow Steel Profile integrates cutting performance, wear resistance, strength, and cost efficiency, making it the ideal upgrade for modern earthmoving and mining equipment.
