Stainless Steel 304 is the most widely used austenitic stainless steel grade due to its outstanding corrosion resistance, excellent fabrication properties, and cost-effectiveness. Stainless Steel 304 pipes and tubes are extensively used in food processing, chemical, construction, pharmaceutical, and industrial applications.

What is Stainless Steel 304?

Stainless Steel 304 is an austenitic chromium-nickel stainless steel that offers excellent resistance to corrosion and oxidation. It is often referred to as “18/8 stainless steel” because it typically contains approximately 18% chromium and 8% nickel.

Stainless Steel 304 pipes and tubes are known for:

  • Excellent corrosion resistance
  • High tensile strength
  • Outstanding formability and weldability
  • Good oxidation resistance
  • Hygienic and easy-to-clean surface
  • Non-magnetic in annealed condition

Because of these versatile properties, Stainless Steel 304 is one of the most commonly used stainless steel grades worldwide.


Chemical Composition of Stainless Steel 304 (%)

  • Chromium (Cr): 18.0 – 20.0%
  • Nickel (Ni): 8.0 – 10.5%
  • Carbon (C): ≤ 0.08%
  • Manganese (Mn): ≤ 2.0%
  • Silicon (Si): ≤ 1.0%
  • Phosphorus (P): ≤ 0.045%
  • Sulfur (S): ≤ 0.03%
  • Iron (Fe): Balance

Role of Alloying Elements

  • Chromium: Provides strong corrosion and oxidation resistance by forming a passive protective layer.
  • Nickel: Enhances ductility, toughness, and resistance to cracking.
  • Low Carbon Content: Reduces risk of carbide precipitation during welding.

This balanced composition ensures long-term durability and resistance to rusting in various environments.


Mechanical Properties of Stainless Steel 304 Pipes and Tubes

Stainless Steel 304 offers excellent mechanical strength suitable for structural and pressure applications.

  • Tensile Strength: ≥ 515 MPa
  • Yield Strength: ≥ 205 MPa
  • Elongation: ≥ 40%
  • Hardness: ≤ 92 HRB

These mechanical properties make Stainless Steel 304 pipes and tubes suitable for fabrication, piping systems, and load-bearing structures.


Physical Properties of Stainless Steel 304

  • 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 304 maintains strength and structural stability across a wide range of temperatures.


Corrosion Resistance of Stainless Steel 304 Pipes and Tubes

Stainless Steel 304 provides excellent resistance to:

  • Atmospheric corrosion
  • Mild chemicals and acids
  • Food and beverage environments
  • Water and steam applications

It performs well in urban and industrial atmospheres. However, in highly chloride-rich environments such as marine conditions, SS 316 may offer better corrosion resistance.
