Are you looking for high-temperature, corrosion-resistant seamless pipes for industrial applications?Our ASTM A312 TP304H, TP316H, and TP310H seamless pipes are engineered to deliver outstanding performance in high-temperature, corrosive, and pressure-intensive environments. Widely used in power plants, chemical processing, oil & gas, and petrochemical industries, these pipes ensure long service life, safety, and reliability.
🔹What Are TP304H, TP316H, and TP310H Pipes?
ASTM A312 specifies seamless and welded stainless steel pipes for high-temperature service.
| Grade | Key Feature | Typical Use |
|---|---|---|
| TP304H | High carbon austenitic steel, excellent for boiler and superheater tubes | Boilers, heat exchangers |
| TP316H | Higher molybdenum content for enhanced corrosion resistance | Chemical, pharmaceutical, marine |
| TP310H | High chromium and nickel for extreme heat resistance | Furnace tubes, kilns, high-temp ducts |
🔹Production Process of ASTM A312TP304H ,TP316H,TP310H Seamless Pipe
To ensure consistent performance under high-temperature conditions, our ASTM A312 H-grade seamless pipes are produced through a strictly controlled process:
Raw Material Inspection – Certified stainless steel billets with full chemical analysis
Hot Piercing – Formation of hollow pipe shell
Hot Rolling / Cold Drawing – Precise control of diameter and wall thickness
Solution Annealing – Improves high-temperature strength and corrosion resistance
Straightening & Cutting – Accurate dimensional control
Surface Treatment – Pickled or polished as required

🔹ASTM A312 TP304H ,TP316H, TP310H Seamless Pipe Specifications
| Property | TP304H | TP316H | TP310H |
|---|---|---|---|
| Chromium (Cr) | 18–20% | 16–18% | 24–26% |
| Nickel (Ni) | 8–10% | 10–14% | 19–22% |
| Carbon (C) | 0.04–0.10% | 0.04–0.10% | 0.04–0.10% |
| Molybdenum (Mo) | - | 2–3% | - |
| Max Service Temp | 900°C | 950°C | 1100°C |
| Tensile Strength (MPa) | 520–750 | 520–750 | 520–700 |
| Yield Strength (MPa) | ≥205 | ≥205 | ≥205 |
🔹 TP304H vs TP316H vs TP310H
TP304H, TP316H, and TP310H are high-carbon (0.04%~0.10%) austenitic stainless steel grades designed for high-temperature applications such as superheaters and reheaters. TP304H offers standard high-temperature strength, TP316H includes molybdenum to enhance corrosion resistance (especially against chloride corrosion) and improve strength, while TP310H provides superior oxidation resistance (>1000°C).
