Txawm li cas los xij, lwm qhov kev xav tseem ceeb yog hluav taws xob conductivity. Cov cuab yeej no tuaj yeem cuam tshuam cov khoom siv hauv ntau yam khoom siv hluav taws xob, hluav taws xob, thiab kev lag luam. Cov lus qhia no piav qhia qhov sib txawv ntawm AISI 304 thiab AISI 316 stainless hlau nyob rau hauv cov nqe lus ntawm hluav taws xob conductivity thiab qhov sib txawv no cuam tshuam rau lawv siv hauv kev lag luam tshwj xeeb.

 

 

Hluav taws xob conductivity yog dab tsi?

Hluav taws xob conductivity yog hais txog cov khoom muaj peev xwm ua hluav taws xob tam sim no. Nyob rau hauv cov hlau zoo li stainless hlau, hluav taws xob conductivity yog feem ntau txiav txim los ntawm qhov ceev ntawm dawb electrons. Feem ntau, cov khoom siv nrog ntau dua nickel thiab chromium cov ntsiab lus zoo li yuav muaj hluav taws xob qis dua vim tias cov ntsiab lus no ua rau cov khoom siv hluav taws xob tuaj yeem ua rau muaj hluav taws xob.

 

Hluav taws xob conductivity nyob rau hauv Stainless hlau

304 stainless hlau yog qib austenitic nrov nrog cov hluav taws xob qis dua piv rau lwm cov hlau xws li tooj liab lossis txhuas.

316 stainless hlau zoo ib yam li 304, tab sis nws muaj 2-3% molybdenum ntxiv, uas ntxiv txo nws cov hluav taws xob conductivity.

AISI 430 (ferritic)	6.00 × 10−7	1.67 × 106	~2.8%

Lus Cim: Ob leeg 304 thiab 316 stainless hlau muaj cov hluav taws xob tsis zoo piv rau cov hlau xws li tooj liab thiab txhuas. Qhov no yog vim cov ntsiab lus siab alloy, uas yog tsim los txhim kho corrosion tsis kam es tsis yog hluav taws xob kev ua tau zoo.

 

Dab tsi yog qhov hluav taws xob conductivity ntawm 304 stainless hlau?

AISI 304 muaj ib qho hluav taws xob conductivity ntawm kwv yees li 1.39 × 106 S / m ntawm 20 degree, sib xws rau cov resistivity ntawm 0.72 µΩ·m (72 µΩ·cm). Qhov no yog kwv yees li 2.3% ntawm tooj liab conductivity. Ib daim ntawv ASM MatWeb rau annealed 304 daim ntawv, tus nqi resistivity yog 7.2 × 10−5 ohm-cm .

 

Puas yog 316 ntau dua lossis tsawg dua kev coj ua dua 304?

Cov hluav taws xob conductivity ntawm 316 yog qis dua me ntsis. Nws cov resistivity yog 0.74 µΩ·m (piv rau 0.72 µΩ·m rau 304), coj mus rau ib tug conductivity ntawm kwv yees li 1.35 × 10⁶ S / m-kwv yees li 2.9% qis dua li ntawm 304. Qhov sib txawv no stems los ntawm molybdenum 3% cov ntsiab lus ntxiv 6-3. scattering chaw nyob rau hauv lub siv lead ua lattice. Hauv kev xyaum ua engineering, txawm li cas los xij, qhov sib txawv no tsis tsim nyog.

Ua haujlwm txias puas hloov cov khoom hluav taws xob ntawm 304 lossis 316?

Yog, txawm tias qhov kev hloov pauv tsawg heev. Cold working increases dislocation density and can induce the formation of strain-induced martensite in metastable austenitic steel grades. Qhov no ua rau 1% mus rau 5% nce hauv hluav taws xob tiv thaiv, nyob ntawm seb qhov ua haujlwm txias.
Ib qho txiaj ntsig tseem ceeb tshaj yog tias kev ua haujlwm txias ua rau muaj kev sib nqus permeability (piv txwv li, magnetism) hauv cov qib steel, nrog Hom 304 ua rau muaj kev cuam tshuam ntau dua rau qhov no dua li Hom 316. Rau cov ntawv thov kom ruaj khov, kwv yees hluav taws xob conductivity lossis tsis yog- cov khoom sib nqus, cov khoom siv hauv cov txheej txheem annealed-ua raws li ASTM cov qauv kev daws teeb meem (ASTM A24) 1040-1120℃tom qab txias txias)-yuav tsum tau teev tseg.
