Cov kev sib piv no tsuas yog kwv yees xwb. Daim ntawv teev npe no yog tsim los ua kev sib piv ntawm cov ntaub ntawv zoo sib xws tsis yog ua daim ntawv teev cov khoom sib npaug. Yog tias xav tau cov khoom sib npaug tiag tiag, yuav tsum tau sab laj nrog cov lus qhia qub.
Cov Qib Lwm Yam Uas Muaj Peev Xwm Hloov Tau
| Qib | Vim li cas nws thiaj yuav raug xaiv es tsis yog 304 |
| 301L | Yuav tsum muaj qib ua haujlwm tawv dua rau qee cov khoom uas dov lossis ncab. |
| 302HQ | Qhov ua haujlwm tawv qis dua yog qhov xav tau rau kev forging txias ntawm cov ntsia hlau, bolts thiab rivets. |
| 303 | Xav tau kev siv tshuab ntau dua, thiab qhov tsis kam tiv taus corrosion, formability thiab weldability qis dua yog qhov siv tau. |
| 316 | Yuav tsum muaj kev tiv thaiv ntau dua rau kev xeb ntawm qhov pitting thiab crevice, nyob rau hauv cov chaw muaj chloride |
| 321 | Yuav tsum muaj kev tiv taus zoo dua rau qhov kub ntawm kwv yees li 600-900 ° C ... 321 muaj lub zog kub dua. |
| 3CR12 | Yuav tsum tau tus nqi qis dua, thiab qhov txo qis kev tiv thaiv corrosion thiab cov xim hloov pauv uas tshwm sim los kuj siv tau. |
| 430 | Yuav tsum tau tus nqi qis dua, thiab qhov kev tiv thaiv corrosion thiab cov yam ntxwv tsim khoom tsawg dua yog qhov siv tau. |
