ASTM A106 Introductio:
1. ASTM A106 pro materia vexillum American, incluso A, B, C tres gradus
American vexillum | Similia Sinica | distrahentes vires |
A | 20# | 330MPa |
B | Q235 | 415MPa, |
C | Q345 | 485MPa |
- Analysis chemica
≤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 |
Superius gradus per C et Mn distinguitur, ergo cum diversis distrahendis viribus.
