Product Description
ASTM A213 TP304L (03Х18Н11) Stainless Steel Seamless Heat-Exchanger Tube
ASTM A213 TP304L Seamless Heat-Exchanger Tube is a premium-grade austenitic stainless steel tube engineered for demanding thermal and corrosive environments. The TP304L designation indicates a low-carbon version of classic 304 stainless steel, providing superior resistance to intergranular corrosion, particularly after welding.
The 03Х18Н11 represents the corresponding GOST standard designation, making this product suitable for international projects requiring specific regional standards. This seamless tubing delivers exceptional performance in high-temperature and high-pressure applications, ensuring reliability in critical systems across power generation, chemical processing, and petrochemical industries.
Standard & Specification
Manufactured in strict compliance with the latest ASTM A213/A 213M standard - "Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes".
- Scope: Seamless tubes designed for service in boilers, superheaters, and heat-exchangers
- Size Range: Available from 1/8 inch (3.2 mm) inside diameter to 5 inch (127 mm) outside diameter, with wall thicknesses from 0.015 to 0.500 inches (0.4 to 12.7 mm)
- Key Feature: The "L" grade (low carbon) minimizes carbide precipitation during welding, ensuring long-term integrity in welded assemblies
Chemical Composition
The chemical composition of TP304L is carefully controlled to ensure optimal corrosion resistance and weldability, with maximized carbon content to prevent chromium carbide formation.
| Element | Standard Requirement |
|---|---|
| Carbon (C) | ≤ 0.035% |
| Chromium (Cr) | 18.00 - 20.00% |
| Nickel (Ni) | 8.00 - 12.00% |
| Manganese (Mn) | ≤ 2.00% |
| Silicon (Si) | ≤ 1.00% |
| Phosphorus (P) | ≤ 0.045% |
| Sulfur (S) | ≤ 0.030% |
Mechanical Properties
TP304L offers an excellent balance of strength and ductility, suitable for both forming operations and high-pressure service.
| Property | Standard Requirement |
|---|---|
| Tensile Strength | ≥ 485 MPa (≥ 70 ksi) |
| Yield Strength (0.2% Offset) | ≥ 170 MPa (≥ 25 ksi) |
| Elongation in 2 inches | ≥ 35% |
Product Applications
This seamless tube is engineered for critical heat transfer applications across various industries:
- Power Generation: Boiler tubes, superheater tubes, and re-heater tubes in fossil fuel and nuclear power plants
- Petrochemical & Chemical Processing: Heat exchangers, condensers, and process piping handling corrosive fluids
- Oil & Gas: Refinery heat exchange systems and surface condensers
