ASTM A106 Introduzzjoni:
1. ASTM A106 għall-materjal standard Amerikan, inkluż a, b, c total ta 'tliet gradi
| Standard Amerikan | Ċiniż simili | Qawwa tat-tensjoni |
| A | 20 # | 330Mpa |
| B | Q235 | 415MPA, |
| C | Q345 | 485Mpa |
- Analiżi kimika
| ≤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 |
Fuq il-grad huwa distint minn C u Mn, allura jiġi b'qawwa tat-tensjoni differenti.
