Qhov Zoo ntawm Stainless Hlau 317L hauv corrosion tsis kam piv rau 304L thiab 316L
Stainless hlau317Lyog kev txhim kho version ntawm316L, raws li nws muaj cov nyiaj ntau duaMolybdenum (mo)thiabnpib tsib caug (ni)Cov. Cov kev sib txawv no hauv tshuaj lom neeg muaj pes tsawg leeg317Ltseem ceeb tsis kam rau qee hom corrosion piv rau304Lthiab316L.
Corrosion Resistance sib piv
|
Hom corrosion |
317L Vs. 316L thiab 304L |
|
Pitting thiab crevice corrosion |
317l yog SuperiorVim nws cov ntsiab lus molybdenum siab dua, uas pab tau nws txoj kev tiv thaiv hauv cov chloride ib puag ncig (xws li dej hiav txwv thiab dej qab ntsev). 304l tsis muaj Molybdenum, thiab 316L muaj tus nqi qis dua. |
|
Intergranular corrosion |
317L thiab 316L yog zoo sib xws, raws li ob qho tib si muaj cov ntsiab lus carbon tsawg, txo cov carbide nag lossis los nag nyob hauv thaj chaw welded. 304l tseem tiv taus tab sis muaj kev tiv thaiv qis dua hauv cov acidic ib puag ncig. |
|
General Corrosion(Acids thiab tshuaj) |
317l stainless hlau seamless yeeb nkab yog cov tiv taus ntauRau cov kua qaub xws li sulfuric, phosphoric, thiab hydrochloric acids vim nws lub siab npib tsib xee thiab molybdenum cov ntsiab lus. 304L thiab 316l yuav txwv tsis pub qeeb nyob hauv cov chaw ib puag ncig no. |
|
Kev ntxhov siab corrosion cracking (SCC) |
317l yog tiv thaiv ntau duaNyob rau hauv qhov kev kub kub-kub thiab cov tshuaj ntsuab uas muaj ntau vim nws cov ntsiab lus tsis muaj txiaj ntsig tsawg dua. |
Cov ntsiab lus tseem ceeb hauv 317L cov tshuaj muaj pes tsawg leeg thiab lawv cov haujlwm

Cov ntsiab lus hauv 317l |
Rooj mov |
|
Chromium (cr) |
18-20% |
Ua cov txheej txheem thev naus laus zis oxide txheej uas tiv thaiv kev tiv thaiv corrosion. |
|
Npib tsib caug (ni) |
11-15% |
Txhim kho corrosion tsis kam nyob rau hauv acidic ib puag ncig thiab txhim kho ductility. |
|
Molybdenum (mo) |
3-4% |
Nce mus rau pitting thiab crevice corrosion hauv chloride thiab acidic ib puag ncig. |
|
Carbon (c) |
Tsawg dua li lossis sib npaug rau 0. 03% |
Cov ntsiab lus muaj cov pa roj carbon qis me me rau carbide tsim, txo qhov kev pheej hmoo ntawm kev sib txuam. |
|
Manganese (mn) |
Tsawg dua los yog sib npaug rau 2% |
Txhim kho kev siv zog thiab ua haujlwm. |
|
Silicon (si) |
Tsawg dua los yog sib npaug rau 0. 75% |
Pab hauv oxidation tiv taus ntawm qhov kub. |
|
Sulphurur (s) & phosphorus (p) |
Tsawg dua li lossis sib npaug rau 0. 03% |
Tam sim no nyob rau hauv me me, txhim kho tshuab kom tsis muaj kev cuam tshuam corrosion. |
