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)

PropertyValue (Typical)
Density7.85 g/cm³
Melting Point~1,425 – 1,538°C
Thermal Conductivity~50 W/m·K
Electrical Resistivity~0.15 μΩ·m
Magnetic PermeabilityFerromagnetic

4. Mechanical Properties of IF Steel

PropertyValue (Typical)
Yield Strength140 – 210 MPa
Tensile Strength270 – 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.
