ASTM A312 TP304L Stainless Steel Pipe Supplier & Exporter in India

ASTM A312 TP304L Stainless Steel Pipe – Detailed Product Description

ASTM A312 TP304L stainless steel pipe is a low-carbon variant of standard 304 grade pipe designed for industrial applications requiring excellent corrosion resistance and superior weldability. TP304L pipes are manufactured under the ASTM A312/ASME SA312 specification, making them suitable for pressure applications in corrosive and high-temperature environments.

Due to its low carbon content, TP304L is especially effective in preventing carbide precipitation during welding, reducing the risk of intergranular corrosion. This makes it ideal for fabrication processes where welding is frequent or when long service life under stress is critical.

Key Features of ASTM A312 TP304L Pipe

  • Superior Corrosion Resistance: Excellent resistance to atmospheric, chemical, and marine corrosion.
  • Low Carbon for Enhanced Weldability: Reduced carbon minimizes carbide precipitation at weld joints.
  • Durability and Longevity: Designed for long service life in aggressive environments.
  • High Fabrication Flexibility: Easy to shape, bend, and weld without cracking.
  • Hygienic and Non-Toxic: Suitable for food, dairy, pharmaceutical, and potable water systems.

Specifications

Chemical Composition

Element Maximum %
Carbon (C)≤ 0.03%
Manganese (Mn)≤ 2.00%
Phosphorus (P)≤ 0.045%
Sulfur (S)≤ 0.030%
Silicon (Si)≤ 1.00%
Chromium (Cr)18.0 – 20.0%
Nickel (Ni)8.0 – 13.0%
Nitrogen (N)≤ 0.10%
Iron (Fe)Balance

This low carbon formula prevents the formation of chromium carbides during welding and high-temperature exposure, maintaining corrosion resistance around welded joints.

Mechanical Properties (Minimum)

Property Value
Tensile Strength≥ 485 MPa
Yield Strength (0.2% proof)≥ 170 MPa
Elongation≥ 35%
Hardness (Brinell)≤ 201 HB

These mechanical properties provide sufficient strength for pressure-bearing applications while retaining excellent ductility for fabrication.
