Dab tsi yog qhov sib txawv ntawm 1.4571 thiab 1.440 cov khoom?

1.4571 thiab 1.4401 Tus Hlau Stainless: Qhov Tseem Ceeb Sib Txawv

Thaum xaiv cov ntaub ntawv stainless hlau rau kev siv cov kev siv, nkag siab txog qhov sib txawv ntawm cov qhab nia yog qhov raug xaiv.1.4571thiab1.4401Ob leeg feem ntau siv austenitic steels, tab sis lawv muaj pes tsawg leeg thiab ua tau zoo sib txawv, ua rau lawv haum rau cov kev xav tau sib txawv. Hauv qab no yog ib qho kev sib piv hauv1.4571 (316Ti)thiab1.4401 (316), Qhia txog qhov tseem ceeb uas yuav muaj txiaj ntsig rau cov kws tshaj lij.

1. Tshuaj lom neeg sib xyaw ua ke thiab cov yam ntxwv

🔹1.4401 Stainless Hlau (316):

Tshuaj Muaj Tshuaj: Feem ntau muaj 16-18 roj ({}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Nws yog dav siv nyob rau hauv cov tshuaj lom neeg, kev ua zaub mov noj, cov tubrog nkoj, thiab tshuaj lag luam.

🔹1.4571 stainless hlau (316ti):

Tshuaj Muaj Tshuaj: Zoo ib yam li1.4401, tab sis1.4571Muaj titanium (ti), feem ntau loj dua los yog sib npaug rau 5 × C%, ntxiv rau chromium, npib tsib xee, thiab molybdenum. Qhov sib ntxiv ntawm titanium stampilizes cov ntsiab lus carbon, tiv thaiv intergranular corrosion, uas yog qhov tseem ceeb thaum cov ntaub ntawv raug mob siab lossis yauv mus rau vuam. Nws yog tshwj xeeb rau haum rau cov kev kub-ib puag ncig.

 

2. Qhov sib txawv tseem ceeb ntawm 1.4571 thiab 1.4401

Kev ua ntsuas kub siab:

🔹1.4401 feem ntau haum rau qhov kub txog 650 degree, ua rau nws haum rau ntau cov ntawv thov kev lag luam. Txawm li cas los xij, 1.4571 tuaj yeem tiv taus kub txog 800 degree, muab tau zoo dua qhov siab kub-kub ruaj khov.

🔹1.c1Petrochemical Nroj TsuagthiabNuclear Fais Fab Noj.

Vuam thiab Pos-Weld Kho:

🔹1.4401 yog ib qho yooj yim rau weld thiab tsis tas yuav tsum tau kho tshav ntuj sov. Txawm li cas los xij, nws yuav raug rau cov rhiab nyob rau thaj chaw kub (Haz), uas tuaj yeem ua rau muaj kev cuam tshuam rau kev txhim kho corrosion.

🔹1.4571 yog tsim los kom tau cov neeg muaj kev kub ntxhov thiab cov khoom siv hnyav ntxiv txo qhov kev pheej hmoo ntawm qhov tsis txaus ntseeg. Yog li ntawd, nws yog qhov zoo dua rau cov chaw ib puag ncig uas vuam tsis tuaj yeem zam (xws li ntau txheej txheem welded pipelines). Thaum vuam 1.4571, kev saib xyuas tshwj xeeb yuav tsum tau coj los tswj cov lus qhia tshav kub, thiab titanium raws li siv cov pob zeb feem ntau siv.

Corrosion Kuj:

🔹1.440 tau ua kom zoo heev rau chloride-ntxias pitting thiab crevice corrosion, ua rau nws cov khoom ntawm kev xaiv marine chaw, kev lag luam khoom noj, thiab tshuaj lag luam.

🔹1.4571 Shares Zoo sib xws rau chloride corrosion, tab sis nws cov ntsiab lus titanium ntxiv txhim kho nws txoj kev tiv thaiv thiab qhov chaw siab. Qhov no ua rau nws xaiv qhov zoo tshaj plaws rau cov ntawv thov xws li cov kav boiler, kev sib txuas kub, thiab kev tso tsheb hlau luam uas nquag tshaj 650 degree.

 

3. Kev Siv Khoom thiab Kev Lag Luam Kev Lag Luam

🔹1.4401 (316 Stainless hlau):

Tshuaj lom neeg: Siv nyob rau hauv reactors, tso tsheb hlau luam, thiab pipelines.

Marine ib puag ncig: Seash Dej hiav txwv Desalination Nroj Tsuag, Khoom Siv Marine.

Cov Khoom Siv Khoom Noj Khoom Haus thiab Khoom Noj Khoom Haus: Vim Nws Corrosion tsis kam thiab yooj yim ntawm kev tu.

🔹1.4571 (316TI Hlau Stainless):

Cov cuab yeej kub-cov khoom kub: Siv hauv cov nroj tsuag fais fab, rauve, thiab cov tshuaj uas muaj tshuaj lom neeg uas nquag muaj qhov kub.

Welded Cheebtsam hauv qhov chaw hnyav: zoo tagnrho rau cov khoom lag luam zoo li tso tsheb hlau luam, kav dej, thiab siab cov hlab ntsha uas raug kub.
