ASTM A106 Ro-ràdh:
1. ASTM A106 airson stuth àbhaisteach Ameireagaidh, a 'toirt a-steach A, B, C Cuibhreann de na trì ìrean
| Ìre Ameireagaidh | Sìneach coltach ris | neart teasile |
| A | 20 # | 330mPA |
| B | Q235 | 415mpa, |
| C | Q345 | 485mpa |
- Sgrìobhadh ceimigeach
| ≤c | Mn | ≤p | ≤s | Si | ≤cr | ≤ca | 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 |
Tha ìre os cionn ìre air a chomharrachadh le C agus MN, agus an uairsin thig e le diofar neart tensile.
