Ntau ntawm txheej tshuab
Raws li qhov xwm txheej, qhov ntau ntawm txheej txheej tshuab raws li hauv qab rooj:
Cov khoom lag luam / khoom siv | Rwb thaiv tsev | Kev ua haujlwm kub (0C) | Corrosion Sitation | Qhov Tsis Yog |
Cov hlau | Tsis | T ≦ 120 | C4 | Txheej Txheem 1 |
Cov hlau | Kub | T ≦ 120 | CUI | Txheej Txheem 2 |
