Our dual capability as a Manufacturer and importer ensures the highest quality control over production and sourcing from well global recognized manufacturers mills. We stock and manufacture TP304 in all standard schedules (Sch 10S, 40S, 80S, etc.) for both seamless and welded requirements. For enhanced weldability, the low-carbon variant, TP304L, is also readily available. Dipti Metal Industries guarantees full compliance, material traceability, and prompt global delivery of our essential TP304 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 TP304 Stainless Steel Pipe & Tube Manufacturer, TP304 Stainless Steel Pipe & Tube importer, TP304 Stainless Steel Pipe & Tube stockist, TP304 Stainless Steel Pipe & Tube supplier, TP304 Stainless Steel Pipe & Tube exporter, TP304 Stainless Steel Pipe & Tube dealer, TP304 Stainless Steel Pipe & Tube distributor, and TP304 Stainless Steel Pipe & Tube trader of general service austenitic stainless steel pipe and tube products from Mumbai, India. ASTM A312 (Pipe) and ASTM A213 (Tube) are the foundational specifications for the classic 18/8 grade, TP304 (1.4301).
TP304 stainless steel is valued for its versatility, excellent forming properties, and corrosion resistance in atmospheric and pure water environments. It is the economical choice for applications that do not involve highly acidic or high-chloride environments. 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 to maximize application flexibility. We ensure all our TP304 piping solutions meet the tensile strength, pressure containment, and general quality requirements of their respective ASTM/ASME standards. We provide a competitive edge through material expertise, full documentation (including EN 10204 3.1/3.2 MTCs), and efficient worldwide deliveries.
TP304 is the original "18/8" stainless steel, achieving its excellent balance of corrosion resistance, strength, and fabricability through the specific ratio of Chromium and Nickel. The composition meets the requirements for both ASTM A312 (Pipe) and ASTM A213 (Tube).
| Element | Weight Percentage (%) | Role in Alloy (TP304) |
|---|---|---|
| Carbon (C) | 0.08 max | Controlled to maintain strength and general formability. (For improved welding, TP304L is recommended.) |
| Manganese (Mn) | 2.00 max | Improves hot working and serves as a deoxidizer. |
| 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 and oxidation resistance (the '18' in 18/8). |
| Nickel (Ni) | 8.00 – 10.50 | Stabilizes the austenitic structure at room temperature; increases toughness (the '8' in 18/8). |
| Nitrogen (N) | 0.10 max | Minor inclusion in this grade. |
For corrosive applications involving welding, customers should often consider the low-carbon version, TP304L, which reduces the risk of intergranular corrosion.
TP304's mechanical strength and high toughness across various temperatures make it suitable for a wide range of pressure and structural applications, as specified by ASTM A312/A213.
Values refer to the solution annealed and pickled condition as per ASTM A312/A213 standards.
Its non-magnetic nature in the annealed condition and good heat transfer properties contribute to its widespread industrial use.
Dipti Metal Industries, your Top TP304 Stainless Steel Pipe & Tube Manufacturer and Supplier, ensures cross-compatibility by providing materials that comply with major international standards, all traceable via certified MTCs.

ASTM A312 TP304 covers seamless and welded pipe intended for general corrosive service and high-temperature use. ASTM A213 TP304 specifically covers seamless tubes for boiler, superheater, and heat exchanger use, having stricter requirements on mechanical testing and heat transfer properties. Dipti Metal is a Top ASTM A312/A213 TP304 Stainless Steel Pipe & Tube Manufacturer, supplying material certified to both specifications where possible.
The industry standard European equivalent for ASTM TP304 (UNS S30400) is the DIN/EN material number 1.4301 (or X5CrNi18-10). This grade represents the classic 18% Chromium, 8% Nickel composition. We also supply TP304L (1.4306/1.4307) for applications requiring improved weldability without post-weld annealing. Dipti Metal guarantees cross-standard traceability for all TP304 grades.
Yes, TP304 has good weldability and is widely used with common fusion welding techniques. However, for severe corrosive service where welding is performed, the low-carbon version, TP304L (UNS S30403), is recommended as it mitigates the risk of sensitization and subsequent intergranular corrosion (weld decay). Dipti Metal stocks and manufactures both TP304 and TP304L to meet specific project weld requirements.
As the most versatile and widely used stainless steel, TP304 pipe is utilized in almost every industry.
