2. What is Interstitial Free Steel (IF Steel) ?
Interstitial Free Steel is a type of ultra-low carbon steel in which interstitial elements such as carbon and nitrogen are removed or neutralized by adding titanium (Ti) or niobium (Nb).
This results in excellent formability, smooth surface finish, and superior elongation properties, making it ideal for demanding deep-drawing and forming applications.
3. Physical Properties of Interstitial Free Steel (IF Steel)
| Property | Value (Typical) |
|---|---|
| Density | 7.85 g/cm³ |
| Melting Point | ~1,425 – 1,538°C |
| Thermal Conductivity | ~50 W/m·K |
| Electrical Resistivity | ~0.15 μΩ·m |
| Magnetic Permeability | Ferromagnetic |
4. Mechanical Properties of IF Steel
| Property | Value (Typical) |
|---|---|
| Yield Strength | 140 – 210 MPa |
| Tensile Strength | 270 – 350 MPa |
| Elongation (A80) | 34 – 42% |
| Hardness (HRB) | 45 – 60 |
| r-value (Lankford Coeff.) | ≥ 1.8 |
5. Key Advantages of Interstitial Free Steel
Exceptional Formability – Perfect for deep drawing and complex shapes.
Excellent Surface Quality – Ideal for high-end painted or coated finishes.
Low Work-Hardening Rate – Reduces springback during forming.
Dimensional Stability – Maintains shape after processing.
Good Weldability – Suitable for spot and seam welding.
6. Potential Limitations
Lower Strength Compared to High-Strength Steels – May not be suitable for load-bearing structural applications.
Requires Protective Coating – Susceptible to corrosion without galvanizing or painting.
Higher Cost Than Ordinary Mild Steel – Due to controlled composition and processing.
7. Main Applications
