Sib piv Properties ntawm 304 vs 316
Thaum ob leeg yog austenitic stainless hlau, lawv cov tshuaj muaj pes tsawg leeg thiab corrosion kuj txawv:
Tshuaj muaj pes tsawg leeg
| Lub ntsiab | SIB 304 | 316 SIB |
|---|---|---|
| Chromium (Cr) | 17.5–20.0 % | 16.0–18.5 % |
| Nickel (Ni) | 8.0–11.0 % | 10.0–14.0 % |
| Molybdenum (hli) | 0 % | 2.0–3.0 % |
Corrosion Resistance
Stainless hlau 304
Qib 304 yog qhov siv dav heev, tus nqi - kev xaiv zoo rau kev siv zaub mov thiab dej haus. Nws muaj kev tiv thaiv zoo rau feem ntau oxidizing acids thiab tsis corrode yooj yim hauv cov txheej txheem kev ua haujlwm.
Txawm li cas los xij, nws muaj qhov cuam tshuam rau pitting corrosion nyob rau hauv chloride-nplua nuj tej yam kev mob, ua rau nws tsis haum rau daim ntaub ntawv uas muaj ntsev los yog briny dej.3
Stainless hlau 316
Qhov sib ntxiv ntawm molybdenum muab 316 stainless hlau txhim khu kev tiv thaiv rau pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv chloride - raug, acidic, los yog siab - qhov kub thiab txias ib puag ncig. Nws ua haujlwm zoo hauv kev ua cov nqaij nruab deg, cov khoom noj muaj kua qaub xws li citrus lossis txiv lws suav, thiab hauv cov chaw uas siv kev tu siab heev-hauv- qhov chaw (CIP) systems.
Hauv cov xwm txheej no, 316 kav ntev dua thiab ua tau zoo dua li 304.3,4
Durability thiab muaj zog
Stainless hlau 304
304 stainless hlau yog paub tias yog tawv thiab txhim khu kev qha. Nws tiv taus kev tu ntau zaus, hnav lub cev, thiab kev ntxhov siab txhua hnub hauv kev lag luam zaub mov.5
Stainless hlau 316
316 yog qhov ruaj khov dua, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej hnyav lossis thaum cov khoom raug cuam tshuam rau cov tshuaj muaj zog lossis siv tas li. Nws yog qhov kev xaiv zoo dua thaum cov khoom siv ntsib kev ntxhov siab tsis tu ncua, cov tshuaj ntxuav tes hnyav, lossis kev tuav tsis zoo. Thaum ob qib muaj zog, 316 muaj zog dua nyob rau hauv qhov xav tau ib puag ncig.3, 5
