Product Description
ASTM A213 T11 tubes are made from a ferritic alloy steel, primarily composed of 1% Molybdenum (Mo), with the balance being carbon, manganese, silicon, phosphorus, sulfur, and small amounts of chromium and other elements. The presence of molybdenum enhances the steel's strength, toughness, and resistance to corrosion at elevated temperatures.
The "T11" grade refers to a specific type of chrome-molybdenum (Cr-Mo) steel. This material is designed to withstand high temperature and pressure conditions, making it ideal for heat transfer applications in power plants, refineries, and chemical plants.
Material Composition
- Chromium (Cr): 1.00 - 1.50%
- Molybdenum (Mo): 0.44 - 0.65%
- Carbon (C): 0.05 - 0.15%
- Manganese (Mn): 0.30 - 0.60%
- Silicon (Si): 0.50 - 0.80%
- Phosphorus (P) & Sulfur (S): Limits set by the specification to ensure high strength and durability
Mechanical Properties
- Tensile Strength: Minimum of 415 MPa (60 ksi)
- Yield Strength: Minimum of 205 MPa (30 ksi)
- Elongation: 30% (in 8 inches) or 35% (in 2 inches)
These properties ensure that the tube can withstand high operating pressures and temperatures typically encountered in power plant boilers or heat exchangers.
Temperature Resistance
Operating Temperature Range: Up to 550°C (1022°F)
T11 alloy steel is known for its excellent heat resistance and is used in applications where the tube is exposed to high-pressure steam or gas for extended periods.
Key Characteristics
- Seamless Construction: Produced without welded seams, enhancing strength and pressure-handling capacity
- Creep and Stress Rupture Resistance: Good creep resistance at high temperatures for power generation applications
- Corrosion Resistance: Exhibits good resistance to oxidizing environments at high temperatures
- Fabricability: Can be easily formed, welded, and machined for specific applications
Applications
- Heat exchangers requiring high thermal conductivity and resistance to pressure/temperature fluctuations
- Superheating sections of steam boilers
- Boiler tubes in power plants and industrial boilers
- Chemical processing applications with high-temperature heat transfer fluids
- Fossil fuel and nuclear power plants requiring reliability and durability
