Yog 316l tib yam li 1.4404?
Hauv kev xyaum, rau ntau cov ntawv thov,En 1.4404thiabAISI 316LLawv suav hais tias yog sib pauv tau. Qhov sib txawv ntawm en 1.440 thiab AISI 316l dag feem ntau nyob rau hauv txoj kev cov qauv no tau txhais thiab nyob rau hauv cheeb tsam uas lawv muaj feem ntau siv.
Dab tsi yog qhov sib npaug ntawm 316L?
1.4404yog cov lej tsim rau qib 316 / 316L Austenitic Stainless hlau raws li cov lus qhia tseeb, raws li nrog lwm cov qib, raws li nrog lwm cov qib, raws li nrog lwm cov qib, raws li nrog lwm cov qib, xws li muaj 1.4301 lossis 1.440 yog nyiam).

Corrosion Kuj
Cov degree316LNws tau ua tau corrosion zoo heev thaum raug rau ntau qhov chaw muaj kev nyab xeeb thiab xov xwm. Stainless hlau yog feem ntau suav tias "marine qib" tab sis tsis muaj kev tiv taus dej hiav txwv kub. Kub chloride ib puag ncig yuav ua rau pitting thiab corrose corrosion. Qeb 316 tseem muaj kev cuam tshuam rau kev ntxhov siab ntawm kev tawg ntawm kev kub siab rau ntau dua 60 degrees.
Kev Kho Cua Sov
Stainless hlau316LNws tsis tuaj yeem yog qhov nyuaj los ntawm kev kho cua sov.
Kev kho cov tshuaj kho lossis annealing tuaj yeem ua los ntawm quenching tom qab cua sov txog 1010-1120 degree.
Muaj zog
Qeb 316L tuaj yeem yooj yim khoov lossis dov rau hauv ntau daim. Nws tseem haum rau stamping, kev sib sau thiab kos duab, tab sis tom qab no yog pom zoo kom txo kev ntxhov siab sab hauv.
Dab tsi yog qhov sib txawv ntawm 1.440 thiab 1.4401 hlau?
Lub ntsiab sib txawv nyob hauv cov ntsiab lus carbon;1.4401muaj cov haib tshaj cov ntsiab lus carbon ntau dua (tsawg dua los yog sib npaug rau 0.07%) dua li1.4404(Tsawg dua los yog sib npaug rau 0.03%). Qhov no txhais tau tias1.4404 (tseem hu ua 316L)Nws yog cov carbon qis version thiab yog li ntawd ntau resistant rau intergranular corrosion, tshwj xeeb tshaj yog tom qab vuam. Txawm hais tias nws lwm cov khoom yog qhov zoo heev, cov ntsiab lus txo cov ntsiab lus ntawm 1.4404 ua rau nws yooj yim rau cov txheej txheem.
Dab tsi yog qhov sib txawv ntawm 1.440 thiab 1.4571?
Qhov sib txawv tseem ceeb yog1.440 (316L)muaj cov ntsiab lus txo cov roj teeb thiab ua kom zoo dua qub thiab tiv taus pitting corrosion, thaum1.4571 (316Ti)Ntxiv Titanium los txhim kho cov cua sov ua kom tsis kam, ua rau nws haum ntau rau cov kev siv kub siab.1.4404Nws yog feem ntau nyiam rau kev tiv thaiv kev xeb thiab cov txheej txheem txias vim nws cov kev coj dawb huv thiab cuam tshuam.
