ASTM A106 Entwodiksyon:
1. ASTM A106 pou materyèl estanda Ameriken an, ki gen ladan A, B, C yon total de twa klas
| Ameriken estanda | Menm jan Chinwa | fòs rupture |
| A | 20# | 330MPA |
| B | Q235 | 415MPA, |
| C | Q345 | 485MPA |
- Chimik analize
| ≤c | Mn | ≤P | ≤s | Si | ≤Cr | ≤cu | Mo | Ni | V | |
| A | 0.25 | 0.27-0.93 | 0.035 | 0.035 | 0.1 | 0.4 | 0.4 | 0.15 | 0.4 | 0.08 |
| B | 0.30 | 0.29-1.06 | 0.035 | 0.035 | 0.1 | 0.4 | 0.4 | 0.15 | 0.4 | 0.08 |
| C | 0.35 | 0.29-1.06 | 0.035 | 0.035 | 0.1 | 0.4 | 0.4 | 0.15 | 0.4 | 0.08 |
Pi wo pase klas distenge pa C ak MN, Lè sa a, li vini ak diferan fòs rupture.
