Material & Manufacturing

Product advantage

1. Superior Mechanical Strength & Durability

• Military-Grade Alloy Steel (AISI 4140/4340) provides ≥850 MPa tensile strength—30% stronger than stamped or cast alternatives.

• Precision Hot Forging ensures optimized grain flow, enhancing impact resistance and fatigue life in high-vibration environments (e.g., wind turbines, railways).

• Quenched & Tempered (HRC 28-32) for balanced hardness and toughness, preventing brittle fractures.

2. High Electrical Performance

• Low Resistance (≤0.2mΩ): CNC-machined contact surfaces ensure efficient current transfer, rated for up to 300A continuous load.

• 35kV Insulation Compatibility: Works with heat-shrink tubes or PVC sleeves for high-voltage applications (substations, renewable energy systems).

3. Corrosion & Wear Resistance

• Multiple Coating Options:

  • Hot-Dip Galvanized (1000+ hours salt spray resistance).

  • Tin-Plated (ideal for copper connections, prevents oxidation).

  • Passivated (chemical-resistant for industrial zones).

• Wide Temperature Range: Performs reliably from -30°C to +200°C.

4. Compliance & Reliability

• Certified: IEC 61238, UL 486A-B, and EN 50149 (railway standards).

• Rigorous QC: Spectrometer material checks + destructive load testing (each batch).

Frequently Asked Questions (FAQ) 

1. What are the key advantages of alloy steel forged lugs over standard lugs?

• 30% Higher Strength: Hot-forged alloy steel (AISI 4140/4340) provides ≥850 MPa tensile strength vs. 600 MPa for mild steel

• Superior Durability: Optimized grain structure resists vibration fatigue (ideal for wind turbines/railways)

• Precision Fit: CNC-machined to ±0.1mm tolerances for perfect cable-to-terminal contact

2. What surface treatments are available for corrosion protection?

• Hot-Dip Galvanized (HDG): 80μm coating, 1000+ hr salt spray resistance (coastal areas)

• Tin-Plated: Best for copper connections, prevents galvanic corrosion

• Bare Steel + Grease: Temporary solution for indoor dry environments

3.How should I store unused lugs?

• Short-term: Keep in original anti-tarnish packaging

• Long-term: Vacuum-seal with desiccant packs

• Never store with dissimilar metals to prevent galvanic corrosion
