Ro-ràdh ASTM A106:
1. ASTM A106 airson an stuth àbhaisteach Ameireaganach, a 'gabhail a-steach A, B, C iomlan de thrì ìrean
Inbhe Ameireaganach | Sìnis coltach ris | neart tensile |
A | 20 # | 330MPa |
B | Q235 | 415MPa, |
C | Q345 | 485 mpa |
- 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 |
Os cionn ìre air a chomharrachadh le C agus Mn, an uairsin thig e le neart tensile eadar-dhealaichte.
