ASTM A213 T9 Alloy Steel Seamless Tube for Boiler Superheater
ASTM A213 T9 is a standard specification for seamless ferritic and austenitic alloy steel boiler, superheater, and heat-exchanger tubes. The T9 grade is a specific chromium-molybdenum alloy steel known for its excellent elevated temperature strength and oxidation resistance.
1. Key Characteristics & Applications
Primary Use: These tubes are primarily designed for high-temperature service environments, making them ideal for:
Power Generation Boilers: Superheater and reheater tubes.
Fossil Fuel Plants: Heat exchangers, condenser tubes, and piping systems.
Petrochemical Industry: Components in refineries and chemical processing equipment where resistance to corrosion and heat is critical.
Main Advantages:
Good Elevated Temperature Strength: Maintains structural integrity and resists creep (deformation under long-term stress at high temperatures).
Oxidation Resistance: The chromium content provides a protective oxide layer, preventing scaling and degradation in oxidizing atmospheres.
Weldability and Formability: Can be welded and fabricated using standard procedures suitable for chromium-molybdenum steels.
2. Chemical Composition
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.15 max |
| Manganese (Mn) | 0.30 - 0.60 |
| Phosphorus (P) | 0.025 max |
| Sulfur (S) | 0.025 max |
| Silicon (Si) | 0.25 - 1.00 |
| Chromium (Cr) | 8.00 - 10.00 |
| Molybdenum (Mo) | 0.90 - 1.10 |
3. Mechanical Properties
| Property | Requirement |
|---|---|
| Tensile Strength | ≥ 415 MPa (60 ksi) |
| Yield Strength | ≥ 205 MPa (30 ksi) |
| Elongation | ≥ 30% (in 2 inches or 50mm) |
4. Manufacturing Standard
The tubes are manufactured as seamless (without a weld seam) through a process like extrusion or piercing, ensuring uniformity and strength throughout the tube's circumference. This makes them highly reliable for high-pressure applications.
