Ukwakheka Kwamakhemikhali: 304 vs 316 vs 201 Uma kuqhathaniswa
Ukuze siqonde ukuthi kungani amagreyidi athile enza kangcono ezimweni zasolwandle, sidinga ukuhlola ukuthi ingxube ngayinye yensimbi engagqwali iquketheni ezingeni lensimbi. Ukumelana nokugqwala kwensimbi engagqwali kuvela ngokuyinhloko kokuqukethwe kwayo kwe-chromium, okwakha ungqimba lwe-chromium oxide olungasebenzi phezu kobuso. Kodwa-ke, izakhi ezengeziwe zokuhlanganisa - ikakhulukazii-nickelfuthii-molybdenum— sidlala indima ebalulekile ekunqumeni ukuthi ungqimba olungasebenzi lumelana kahle kangakanani nokuhlaselwa kwe-chloride ezindaweni zokufutha usawoti. Sithola izinto zethu zokusetshenziswa njengemicu yensimbi engagqwali egoqekile ebandayo, futhi siqinisekisa ukwakheka kwamakhemikhali kweqoqo ngalinye ngaphambi kokuba kuqale ukukhiqizwa.
Nansi indlela la mabanga amathathu aqhathaniswa ngayo ekwakhiweni kwawo kwamakhemikhali okuqanjiwe:
| Isici | 304 (18Cr-8Ni) | 316 (16Cr-10Ni-2Mo) | 201 (17Cr-4.5Ni-6Mn) |
|---|---|---|---|
| I-Chromium (Cr) | 18.0 – 20.0% | 16.0 – 18.0% | 17.0 – 19.0% |
| I-Nickel (Ni) | 8.0 – 10.5% | 10.0 – 14.0% | 1.0 – 5.0% |
| I-Molybdenum (Mo) | Akukho | 2.0 – 3.0% | Akukho |
| I-Manganese (Mn) | Ubuningi obungu-2.0% | Ubuningi obungu-2.0% | 5.5 – 7.5% |
| I-nitrogen (N) | Umkhawulo ongu-0.10% | Umkhawulo ongu-0.10% | Umkhawulo ongu-0.25% |
