ASTM A106 Pengenalan:
1. ASTM A106 kanggo materi standar Amérika, kalebu A, B, C total telung gelar
standar Amérika | Cina sing padha | kekuatan tarik |
A | 20# | 330MPa |
B | Q235 | 415MPa, |
C | Q345 | 485MPa |
- Analisis kimia
≤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 |
Ndhuwur bahan dibedakake dening C lan Mn, banjur teka kanthi kekuatan tarik sing beda.
