Ro-ràdh ASTM A106:
1. ASTM A106 airson an stuth àbhaisteach Ameireaganach, a’ gabhail a-steach trì ìrean A, B, C gu h-iomlan
| Inbhe Ameireaganach | Sìneach coltach ris | neart tensile |
| A | 20 # | 330MPa |
| B | Q235 | 415MPa, |
| C | Q345 | 485MPa |
- Mion-sgrùdadh ceimigeach
| ≤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 |
Tha ìre os cionn air a chomharrachadh le C agus Mn, agus an uairsin thig e le neart tensile eadar-dhealaichte.
