Mechanical Properties for ASTM A312 Pipes
The ASTM A312 standard specifies minimum mechanical properties for different grades, ensuring durability and reliable performance in high-stress and high-temperature applications. The tensile strength, yield strength, and elongation requirements are as follows:
| Grade | Tensile Strength (PSI Min) | Yield Strength (PSI Min) | Elongation % (Min) |
|---|---|---|---|
| TP304 | 75,000 | 30,000 | 35 |
| TP304L | 70,000 | 25,000 | 35 |
| TP304H | 75,000 | 30,000 | 35 |
| TP316 | 75,000 | 30,000 | 35 |
