Stainless Steel 304L is a low-carbon version of SS 304, designed to minimize carbide precipitation during welding. This makes Stainless Steel 304L ideal for applications requiring extensive welding while maintaining excellent corrosion resistance.

What is Stainless Steel 304L?

Stainless Steel 304L is an austenitic chromium-nickel stainless steel with a reduced carbon content (≤0.03%) compared to standard SS 304. This low carbon content prevents sensitization, which can lead to intergranular corrosion after welding.

Stainless Steel 304L pipes and tubes are known for:

  • Excellent corrosion resistance in mild to moderate environments
  • High tensile strength and durability
  • Superior weldability without post-weld annealing
  • Good formability and machinability
  • Non-magnetic in annealed condition
  • Hygienic and easy-to-clean surface

Because of these properties, Stainless Steel 304L is widely used in chemical, food, pharmaceutical, and architectural applications.


Chemical Composition of Stainless Steel 304L (%)

  • Chromium (Cr): 18.0 – 20.0%
  • Nickel (Ni): 8.0 – 12.0%
  • Carbon (C): ≤ 0.03%
  • Manganese (Mn): ≤ 2.0%
  • Silicon (Si): ≤ 1.0%
  • Phosphorus (P): ≤ 0.045%
  • Sulfur (S): ≤ 0.03%
  • Iron (Fe): Balance

Role of Alloying Elements

  • Chromium: Forms a protective oxide layer to resist corrosion.
  • Nickel: Improves toughness, ductility, and resistance to cracking.
  • Low Carbon Content: Reduces carbide precipitation during welding, preventing intergranular corrosion.

This composition makes Stainless Steel 304L pipes and tubes ideal for welded structures and pressure piping.

Stainless Steel 304L offers excellent mechanical performance suitable for structural and process applications:

  • Tensile Strength: ≥ 485 MPa
  • Yield Strength: ≥ 170 MPa
  • Elongation: ≥ 40%
  • Hardness: ≤ 90 HRB

These properties allow Stainless Steel 304L pipes and tubes to withstand mechanical stress and thermal cycles effectively.


Physical Properties of Stainless Steel 304L

  • Density: 7.93 g/cm³
  • Melting Range: 1400 – 1450°C
  • Thermal Conductivity: 16.2 W/m·K
  • Modulus of Elasticity: 193 GPa
  • Electrical Resistivity: 0.72 µΩ·m

Stainless Steel 304L maintains strength, stability, and corrosion resistance under typical operating temperatures and pressures.
