ASTM A688 is a standard that outlines the requirements for welded austenitic stainless steel pipes used in feedwater heater heat exchangers. These pipes are available in various grades, including 304, 316, 304L, 316L, and XM-29. Each grade offers specific properties suitable for different applications. The key features of these pipes include:
The following table presents the chemical composition of the different steel grades used in ASTM A688 pipes:
| Steel Grade | C (%) | Mn (%) | P (%) | S (%) | Si (%) | Cr (%) | Ni (%) | Mo (%) |
|---|---|---|---|---|---|---|---|---|
| 304 | 0.08 | 2.00 | 0.045 | 0.030 | 0.75 | 18-20 | 8-10.5 | - |
| 316 | 0.08 | 2.00 | 0.045 | 0.030 | 0.75 | 16-18 | 10-14 | 2-3 |
| 304L | 0.03 | 2.00 | 0.045 | 0.030 | 0.75 | 18-20 | 8-12 | - |
| 316L | 0.03 | 2.00 | 0.045 | 0.030 | 0.75 | 16-18 | 10-14 | 2-3 |
