Dipti Metal Industries, a Worldwide recognized, Largest, Best, and Top ASTM A312/A213 TP304L Stainless Steel Pipe & Tube Manufacturer, TP304L Stainless Steel Pipe & Tube importer, TP304L Stainless Steel Pipe & Tube stockist, TP304L Stainless Steel Pipe & Tube supplier, TP304L Stainless Steel Pipe & Tube exporter, TP304L Stainless Steel Pipe & Tube dealer, TP304L Stainless Steel Pipe & Tube distributor, and TP304L Stainless Steel Pipe & Tube trader from Mumbai, India, specializes in the production and supply of the **Low-Carbon austenitic stainless steel grade: TP304L (UNS S30403, 1.4307). Certified primarily under **ASTM A312** for pipe and **ASTM A213** for seamless tube, this grade's maximum carbon content is limited to 0.03%, making it the superior choice for welded fabrication in corrosive environments.
The intentionally low carbon content in TP304L is critical for eliminating the risk of sensitization—where Chromium carbides precipitate during welding's heat-affected zone cycling—thereby preserving the material's corrosion resistance without the need for post-weld solution annealing. This makes it indispensable for large-scale welded structures, chemical tanks, and continuous piping systems in the Chemical, Food, and Pharmaceutical industries. Our dual capability as a Manufacturer and importer ensures the highest quality control over production and sourcing from well global recognized manufacturers mills. We guarantee full compliance, material traceability, and prompt global delivery of our essential TP304L piping solutions, backed by EN 10204 3.1/3.2 MTCs.
Dipti Metal Industries stands as a Worldwide recognized, Largest, Best, and Top ASTM A312/A213 TP304L Stainless Steel Pipe & Tube Manufacturer, TP304L Stainless Steel Pipe & Tube importer, TP304L Stainless Steel Pipe & Tube stockist, TP304L Stainless Steel Pipe & Tube supplier, TP304L Stainless Steel Pipe & Tube exporter, TP304L Stainless Steel Pipe & Tube dealer, TP304L Stainless Steel Pipe & Tube distributor, and TP304L Stainless Steel Pipe & Tube trader of the low-carbon austenitic stainless steel grade from Mumbai, India. ASTM A312 (Pipe) and ASTM A213 (Tube) are the foundational specifications for TP304L (1.4307).
TP304L is the essential variant of stainless steel wherever welding is performed in components intended for corrosive service. Its maximum carbon content of 0.03% is specifically required to minimize chromium carbide precipitation during the welding process's thermal cycle, thereby eliminating the risk of intergranular corrosion (weld decay) in the heat-affected zone. Our comprehensive inventory, supported by both in-house Manufacturing and global sourcing from well global recognized manufacturers mills, includes both Seamless (SMLS) and Welded (ERW) forms, often dual-certified as TP304/304L. We ensure all our TP304L piping solutions are fully tested, and we provide a competitive edge through material expertise, full documentation (including EN 10204 3.1/3.2 MTCs), and efficient worldwide deliveries.
The composition of TP304L is defined by its low carbon content, the primary feature that grants it immunity to intergranular corrosion after welding. This composition meets the requirements for both ASTM A312 (Pipe) and ASTM A213 (Tube).
| Element | Weight Percentage (%) | Role in Alloy (TP304L) |
|---|---|---|
| Carbon (C) | 0.030 max | Key element; limits carbon to prevent weld decay. |
| Manganese (Mn) | 2.00 max | Improves hot working. |
| Phosphorus (P) | 0.045 max | Impurity control. |
| Sulfur (S) | 0.030 max | Impurity control. |
| Silicon (Si) | 1.00 max | Improves oxidation resistance. |
| Chromium (Cr) | 18.00 – 20.00 | Provides fundamental corrosion resistance. |
| Nickel (Ni) | 8.00 – 12.00 | Stabilizes the austenitic structure and increases toughness. |
The maximum 0.03% carbon content is critical. This material should always be specified for any welded assembly that will be exposed to a corrosive service environment.
TP304L shares similar corrosion and physical properties with TP304, but its mechanical properties are slightly lower due to the reduced carbon content, though it remains a robust pressure-containing alloy.
Note the lower minimum Yield Strength compared to standard TP304 (205 MPa), a trade-off for superior weldability. Many products are dual-certified (A312 TP304/304L).
Due to its lower strength at elevated temperatures, TP304L is not an 'H' grade and should not be used for high-temperature pressure service above 450°C/842°F.

TP304L (Low Carbon) is preferred for welding because its maximum carbon content is capped at 0.03% (compared to 0.08% for TP304). This extremely low carbon level prevents the formation of chromium carbides at grain boundaries during welding heat cycles, thus eliminating the risk of intergranular corrosion (weld decay) in subsequent corrosive service, even without post-weld annealing. Dipti Metal is a Top ASTM A312 TP304L Stainless Steel Pipe & Tube Manufacturer for projects requiring complex welding.
The industry standard European equivalent for ASTM TP304L (UNS S30403) is the DIN/EN material number 1.4307 (or X2CrNi18-9). This is the low-carbon version of 1.4301. We often supply dual-certified material (e.g., A312 TP304/304L) where the mechanical requirements of TP304 are met while utilizing the low carbon content of TP304L. Dipti Metal guarantees full cross-standard traceability for all TP304L grades.
Generally, no. The lower carbon content in TP304L leads to a slightly reduced yield strength at room temperature compared to standard TP304. However, the tensile strength is typically the same. Many manufacturers supply dual-certified TP304/304L, where the material technically meets the mechanical property floor of TP304 while retaining the low carbon of TP304L. For any application requiring minimum TP304 strength, the material certificate must explicitly state it meets the TP304 requirements.
TP304L pipe is essential in corrosive environments where the material will be welded and post-weld solution annealing is either cost-prohibitive or physically impossible. Primary uses include large welded structures, chemical tanks, pharmaceutical equipment, pipelines in corrosive environments, and components for brewery and dairy industries. Dipti Metal is a Best TP304L Stainless Steel Pipe & Tube Exporter for the Chemical and Processing sectors globally.
As a comprehensive Manufacturer and Stockist, we supply TP304L in Seamless Pipe (A312), Welded Pipe (A312), Seamless Tube (A213/A269), Welded Tube (A249), and matching components like Fittings (A403 WP304L) and Flanges (A182 F304L). All products come with verifiable MTCs (EN 10204 3.1 or 3.2) guaranteeing the low carbon content and corrosion test results.
