ASTM A213 is a standard specification for austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. These stainless steel tubes are widely used for various industrial applications, thanks to their excellent heat-resistance, corrosion-resistance, and exceptional mechanical properties.
The ASTM A213 specification covers seamless ferritic and austenitic alloy-steel tubes for boilers, superheaters, and heat exchangers. These tubes are particularly suitable for high-temperature, corrosive environments.
The material used for ASTM A213 tubes is categorized into five different grades: TP304, TP304L, TP316, TP316L, and TP347. Each grade offers unique properties suitable for specific applications.
The chemical composition of ASTM A213 stainless steel tubes varies depending on the grade. The table below presents the approximate chemical composition for each grade:
| Grade | C | Mn | P | S | Si | Ni | Cr | Mo |
|---|---|---|---|---|---|---|---|---|
| TP304 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 8.00-11 | 18.00-20 | - |
| TP304L | 0.035 | 2.00 | 0.045 | 0.030 | 1.00 | 8.00-13 | 18.00-20 | - |
| TP316 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 10.00-14 | 16.00-18 | 2.00-3.00 |
| TP316L | 0.035 | 2.00 | 0.045 | 0.030 | 1.00 | 10.00-15 | 16.00-18 | 2.00-3.00 |
| TP347 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 9.00-13 | 17.00-19 | - |
The mechanical properties of ASTM A213 stainless steel tubes are crucial for their suitability in boiler and heat exchanger applications. The table below displays the typical mechanical properties of each grade:
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HV) |
|---|---|---|---|---|
| TP304 | ≥515 | ≥205 | ≥35 | ≤192 |
| TP304L | ≥485 | ≥170 | ≥35 | ≤192 |
| TP316 | ≥515 | ≥205 | ≥35 | ≤192 |
| TP316L | ≥485 | ≥170 | ≥35 | ≤192 |
| TP347 | ≥515 | ≥205 | ≥35 | ≤192 |
ASTM A213 stainless steel tubes find extensive use in various industrial applications, primarily in boilers and heat exchangers. Due to their excellent corrosion resistance and high-temperature strength, these tubes are ideal for transferring heat between fluid media.
Boilers rely on ASTM A213 seamless tubes to withstand high pressures and temperatures, ensuring efficient heat transfer and smooth operation. Heat exchangers, on the other hand, utilize these tubes to transfer heat between two or more fluids while maintaining optimal performance.
Additionally, ASTM A213 stainless steel tubes are also employed in industries such as petroleum, chemical, pharmaceutical, and power generation, where corrosion resistance and heat transfer capabilities are essential.
ASTM A213 stainless steel tubes play a significant role in the operation and efficiency of boilers and heat exchangers. With their excellent heat-resistance, corrosion-resistance, and mechanical properties, these tubes offer reliable performance even in demanding environments.
