Properties of Pure Iron: A Technical Guide by SLH Pure Iron

1. Fundamental Properties of Pure Iron

Pure iron (≥99.8% Fe) serves as the cornerstone of modern metallurgy. As a leading pure iron manufacturer,SLH Pure Iron explores its intrinsic properties that drive applications across industries.

Fatigue & Creep Resistance

- Fatigue Limit: 150–200 MPa (10⁷ cycles, R=−1)

- Creep Threshold: 450°C (0.5% strain/10,000h)

-Applications: Turbine shafts, precision gears requiring long-term stability.

Electrical Conductivity Optimization

- Impurity Impact:

- Carbon ↑1% → Conductivity ↓15%

- Oxygen ↑100 ppm → Resistivity ↑8%

Beilun's Solution: Proprietary deoxidation tech maintains resistivity at 9.7 μΩ·cm(99.99% Fe).

Technological Advantages

- Purity Control: Hydrogen/Nitrogen decarburization for C ≤0.008%

- Inclusion Engineering: ASTM E45 A-S1 ≤0.5 (vs. standard ≤2)

- Customization: 200+ alloy variants (e.g., Fe-Si, Fe-P)
