Isingeniso se-ASTM A106:
1. I-ASTM A106 yezinto ezijwayelekile zaseMelika, okuhlanganisa u-A, B, C ingqikithi yamabanga amathathu
Izinga laseMelika | IsiShayina esifanayo | amandla aqinile |
A | 20# | 330MPa |
B | Q235 | 415MPa, |
C | Q345 | 485MPa |
- Ukuhlaziywa kwamakhemikhali
≤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 |
Ibanga elingenhla lihlukaniswa ngu-C no-Mn, bese liza namandla ahlukene okudonsa.
