| Vanadium (V) | Inqas minn jew daqs 0.02 | Inqas minn jew daqs 0.02 |
🔍 Differenzi nnotati:
Grad B jippermetti manganiż kemmxejn ogħla.
Il-Grad A jippermetti kontenut ogħla tas-silikon, possibilment li jinfluwenza l-weldabilità.
Iż-żewġ gradi fihom elementi ta 'liga bħal Cu, Cr, u Ni għar-reżistenza għall-korrużjoni atmosferika.
Reżistenza għall-korrużjoni
Iż-żewġ gradi huma azzar tat-temp b'reżistenza simili għall-korrużjoni, li jiffurmaw saff ta 'ossidu protettiv (patina). Huma adattati għal:
Pontijiet ta 'barra
Bini
Komponenti strutturali f'ambjenti kostali jew industrijali
Applikazzjonijiet tipiċi
| Grad A. | Grad B. |
|---|---|
| Pontijiet | Karozzi tal-ferrovija |
| Bini strutturali | Bini |
| Torrijiet tat-Trasmissjoni | Pollakki, torrijiet |
| Kontenituri u vapuri | Tagħmir tal-kostruzzjoni |
Sommarju: Meta tagħżel VS B
Agħżel Grad A jekk id-disinn jipprijoritizza l-weldabilità u kontenut ogħla tas-silikon huwa aċċettabbli.
Agħżel il-Grad B għal sezzjonijiet kemmxejn eħxen jew meta kontenut ogħla ta 'manganiż jista' jtejjeb il-formabilità jew l-impatt ta 'ebusija.
