ASTM A376 TP347H Seamless Stainless Steel Pipe For Petrochemical Industry
ASTM A376 TP347H is a high-temperature, corrosion-resistant, seamless stainless steel pipe widely used in demanding industrial applications. It is part of the austenitic stainless steel family, specifically developed for elevated temperature environments where resistance to creep and oxidation is required.
Key Features
High-Temperature Strength:
TP347H contains columbium (niobium) and high carbon content, which enhance its creep strength and long-term stability at elevated temperatures.
Corrosion Resistance:
Excellent resistance to intergranular corrosion due to stabilized elements, making it suitable for applications involving aggressive environments.
Seamless Construction:
The seamless design ensures high mechanical strength and eliminates weak points, providing durability under high pressures and temperatures.
Oxidation Resistance:
Resistant to oxidation at temperatures up to 870–980°C (1600–1800°F), making it ideal for heat exchangers, boilers, and superheaters.
Chemical Composition (Typical)
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.04–0.10 |
| Chromium (Cr) | 17.0–19.0 |
| Nickel (Ni) | 9.0–13.0 |
| Manganese (Mn) | ≤2.0 |
| Silicon (Si) | ≤1.0 |
| Phosphorus (P) | ≤0.045 |
| Sulfur (S) | ≤0.030 |
| Niobium (Cb) | 10×C to 1.0 |
Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | ≥515 MPa (75 ksi) |
| Yield Strength (0.2%) | ≥205 MPa (30 ksi) |
| Elongation | ≥35% |
| Hardness (Brinell) | ≤223 HB |
