DIPTI METAL INDUSTRIES
ASTM A312 TP304H Stainless Steel Pipe & Tube Manufacturer, TP304H Stainless Steel Pipe & Tube Importer, TP304H Stainless Steel Pipe & Tube Stockist, TP304H Stainless Steel Pipe & Tube Supplier & TP304H Stainless Steel Pipe & Tube Exporter in Mumbai, India | Global Supplier of High-Carbon 1.4948 Pipes
Dipti Metal Industries, a Worldwide recognized, Largest, Best, and Top ASTM A312 TP304H Stainless Steel Pipe & Tube Manufacturer, TP304H Stainless Steel Pipe & Tube importer, TP304H Stainless Steel Pipe & Tube stockist, TP304H Stainless Steel Pipe & Tube supplier, TP304H Stainless Steel Pipe & Tube exporter, TP304H Stainless Steel Pipe & Tube dealer, TP304H Stainless Steel Pipe & Tube distributor, and TP304H Stainless Steel Pipe & Tube trader from Mumbai, India, specializes in the production and supply of **High-Carbon austenitic stainless steel grade: TP304H (UNS S30409). This 'H' grade is a modification of standard TP304, featuring a controlled carbon range (0.04% to 0.10%) and coarse grain size specifically designed to maximize creep and stress-rupture strength for high-temperature pressure applications (up to 800°C).
The intentionally higher carbon content in TP304H increases the material's internal resistance to deformation over long periods at high heat, a phenomenon known as creep, which is critical for pressure piping and boiler components. This feature makes it the required material for many components operating above 500°C in power generation and refinery units, where standard TP304/304L is inadequate. 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 specialized TP304H piping solutions, backed by EN 10204 3.1/3.2 MTCs.
Overview: Dipti Metal Industries - Your Leading ASTM A312 TP304H Stainless Steel Pipe & Tube Manufacturer & Supplier
Dipti Metal Industries stands as a Worldwide recognized, Largest, Best, and Top ASTM A312 TP304H Stainless Steel Pipe & Tube Manufacturer, TP304H Stainless Steel Pipe & Tube importer, TP304H Stainless Steel Pipe & Tube stockist, TP304H Stainless Steel Pipe & Tube supplier, TP304H Stainless Steel Pipe & Tube exporter, TP304H Stainless Steel Pipe & Tube dealer, TP304H Stainless Steel Pipe & Tube distributor, and TP304H Stainless Steel Pipe & Tube trader of high-carbon austenitic stainless steel pipe and tube products from Mumbai, India. **ASTM A312 (Pipe)** and **ASTM A213 (Tube)** are the specifications used for the 'H' grade, TP304H (UNS S30409).
The **'H' designation** (High Carbon) mandates a carbon range of 0.04% to 0.10%, significantly higher than the max 0.03% allowed for TP304L. This increased carbon, combined with a specified coarse grain size requirement, is crucial for improving the **creep and stress-rupture properties** of the alloy at elevated service temperatures (above 500°C). Our comprehensive inventory, supported by both in-house Manufacturing and global sourcing from well global recognized manufacturers mills, ensures our TP304H piping solutions meet the stringent creep performance requirements of ASME Boiler and Pressure Vessel Codes. We provide a competitive edge through material expertise, full documentation (including EN 10204 3.1/3.2 MTCs), and efficient worldwide deliveries.
Chemical Composition of ASTM A312 TP304H Stainless Steel (UNS S30409)
The composition of TP304H is identical to TP304/TP304L in most elements, but with a specific, tightly controlled carbon range that dictates its high-temperature strength performance. The carbon content must be a minimum of 0.04%.
| Element | Weight Percentage (%) | Role in Alloy (TP304H) |
|---|---|---|
| Carbon (C) | 0.04 min – 0.10 max | Key element for creep and stress-rupture strength at high temperatures. |
| 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 and oxidation resistance. |
| Nickel (Ni) | 8.00 – 10.50 | Stabilizes the austenitic structure and increases toughness. |
The high carbon content of TP304H makes it susceptible to sensitization (weld decay) if held in the 427°C-816°C range, meaning it is typically used in applications where either the operating temperature is above this range or where corrosion concerns are minimal.
Mechanical & Physical Properties of A312 TP304H Pipe/Tube
The mechanical properties of TP304H are tailored for long-term reliability in high-temperature environments, often requiring higher minimum values and demanding rigorous creep testing to certify performance.
Mechanical Properties (Minimum at Room Temp)
Values refer to the coarse grain size solution annealed condition. The main performance gain is in long-term high-temperature rupture strength, not in room-temperature figures.
Physical Properties (Typical)
The coarse grain size is a mandatory physical requirement to enhance creep resistance at high temperatures, distinguishing it from standard TP304.

ASTM A312 TP304H Stainless Steel Pipe & Tube — Frequently Asked Questions
The 'H' designation signifies controlled High Carbon content (0.04% to 0.10%). This increased carbon content is intentionally introduced because it significantly enhances the material's creep and stress-rupture strength at service temperatures exceeding 500°C (932°F). Creep resistance is critical for boiler and pressure piping applications where the material must maintain structural integrity under load over long periods at high temperatures. Dipti Metal is a Top ASTM A312 TP304H Stainless Steel Pipe & Tube Manufacturer for the Energy sector.
TP304H is exclusively required for pressure vessel and piping applications that operate at elevated temperatures (typically 500°C to 800°C) and require certified creep data. Standard TP304/304L loses significant strength at these temperatures. TP304H is commonly used in high-temperature heat exchangers, superheater tubes (A213H), boiler components, and large diameter process piping where creep resistance is mandatory. Dipti Metal ensures that our TP304H material meets all mandated grain size and carbon range requirements.
The industry standard European equivalent for ASTM TP304H (UNS S30409) is the DIN/EN material number 1.4948 (or X6CrNi18-11). This is a widely accepted European grade specifically designed for high-temperature pressure vessel service. Dipti Metal guarantees cross-standard traceability for all TP304H materials supplied from our manufacturing and stocking base.
No. The 'H' designation in ASTM A312 refers purely to the controlled chemical composition and microstructure (i.e., coarse grain size and carbon content) required for high-temperature mechanical performance. The pipe dimensions (Outer Diameter, Wall Thickness, and Schedule) follow the same ASME B36.10M or B36.19M standards as standard TP304 or TP304L pipes. Dipti Metal supplies TP304H in all standard schedules (Sch 40, Sch 80, etc.).
As a quality-focused TP304H Stainless Steel Pipe & Tube Manufacturer and Supplier, every delivery of ASTM A312 TP304H pipe includes mandatory Mill Test Certificates (MTCs), specifically the EN 10204 3.1 certificate. We also offer EN 10204 3.2 certification with Third-Party Inspection (TPI) on request, verifying the precise carbon range and performing creep/rupture tests as mandated by high-temperature specifications.
