310 vs 310s stainless hlau: corrosion tsis kam
Apr 02, 2025
Tso lus
310 thiab 310s Stainless hlau yog ob qho tib si High-alloy Austenitic Stainless hlau, feem ntau yog siv nyob rau hauv qhov chaw kub. Lawv cov corrosion tsis zoo yog zoo sib xws hauv feem ntau cov xwm txheej, tab sis cov kev ua tau zoo tshaj plaws vim muaj kev sib txawv hauv cov ntsiab lus carbon. Cov hauv qab no yog kev sib piv ntawm cov xeb tiv thaiv ntawm ob thiab xaiv cov lus qhia:
310 vs. 310s Stainless Hlau: Tshuaj lom neeg muaj pes tsawg leeg
| Lub ntsiab | 310 Tus Hlau Stainless (Wt%) | 310s stainless hlau (wt%) |
|---|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0. 25 | Tsawg dua los yog sib npaug rau 0. 08 |
| Chromium (cr) | 24.0–26.0 | 24.0–26.0 |
| Npib tsib caug (ni) | 19.0–22.0 | 19.0–22.0 |
| Manganese (mn) | Tsawg dua los yog sib npaug rau 2. 00 | Tsawg dua los yog sib npaug rau 2. 00 |
| Silicon (si) | Tsawg dua los yog sib npaug rau 1.50 | Tsawg dua los yog sib npaug rau 1.50 |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0. 045 | Tsawg dua los yog sib npaug rau 0. 045 |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0. 030 | Tsawg dua los yog sib npaug rau 0. 030 |
310 vs 310s stainless hlau: corrosion tsis kam
Qhov kub kub oxidation kub
Ob qho tib si ntawm lawv daim qauv xim oxide oxide (cr₂o₃) los ntawm chromium, tab sis feem ntau yuav tsim cov ntsiab lus ntawm cov duab tshiab ntawm cov yeeb yaj kiab oxide thiab yuav tsum tau saib xyuas ntev ntev. 310s yog qhov zoo los ntawm cov roj carbon tsawg + siab npib siab, nrog rau cov zog tiv thaiv oxidation ruaj khov siv ntsuas kub ntawm 1200 degree.
Acidic Nruab Nrab
31 {0 s: Nws ua tau zoo nyob rau hauv muaj zog oxidizing cov kua qaub, muaj rau cov khoom siv tshuaj tsw qab rau cov tshuaj lom neeg thiab cov khoom siv.
310: Nws muaj cov kua qaub tsis muaj zog, tshwj xeeb tshaj yog nyob rau hauv cov sulfuric acid, thiab muaj feem ntau tsim nyog corrosion, uas yog qhov tsim nyog rau nruab nrab lossis tsis muaj zog acid scenarios.
Chloride Ib puag ncig
310s muaj cov ntsiab lus tsis loj dua ({} ion) ib puag ncig ntawm 310. Hauv kev siv tshuaj tsw qab ntau dua li 310. Hauv kev sib pauv ntawm ntug hiav txwv thiab dej hiav txwv.
Alkaline Ib Cheeb Tsam
Ob qho tib si tuaj yeem tiv thaiv muaj zog alkali corrosion xws li sodium hydroxide, tab sis tus npib tsib ncia ua rau nws ruaj khov nyob rau hauv cov kev daws teeb meem kub, xws li cov ntawv kev lag luam kev lag luam khoom siv.
Cov lus qhia rau kev yuav khoom 310 Stainless Hlau Kav
Ntshiab ib puag ncig:Ua ntej xeem tau qhov nruab nrab muaj pes tsawg leeg, ntsuas kub thiab lub siab kom tsis txhob siv cov khoom siv tsis ua haujlwm yog vim muaj nag los nag lossis pitting.
Yuav tsum muaj cov vuam ua vuam:Yog tias yuav tsum muaj vuam hnyav (xws li cua sov ua kom sov cov ntawv sib dhos), xaiv 310s los txo txoj kev pheej hmoo ntawm tom qab-weld intergranular corrosion.
Tus nqi txiav txim siab:Tus nqi ntawm 310 yog hais txog 10-15% tus nqi ntev dua 310, tab sis lub sijhawm tu ncua ntev yog qis dua, uas yog qhov tsim nyog rau cov khoom siv peev.
