Nyob rau hauv OCT, Kub Muag, 1000PCS SS310 Stainless hlau pas nrig packed rau xa mus rau peb cov neeg muas zaub nyob rau hauv Philippines.High zoo cov khoom nrog zoo packing.
Stainless hlau rods yog siv nyob rau hauv ntau lub teb vim hais tias lawv muaj ntau resistant rau xeb tshaj hlau thiab muaj corrosion kuj. Thaum ua cov hlau tsis huv, nws yog ib qho tseem ceeb kom paub qhov kub thiab txias uas cov khoom tuaj yeem tiv taus.
Muaj ntau hom stainless hlau, txhua tus muaj qhov sib txawv ntawm qhov kub thiab txias. Raws li hom stainless hlau, nws muaj cov lus qhia sib txawv, yog li paub txog qhov kub-resistant kub ua ntej yuav pab koj xaiv cov khoom tsis muaj teeb meem.
Lub sijhawm no, peb yuav qhia txog qhov ntsuas kub-resistant ntawm ntau yam stainless hlau thiab cov yam ntxwv ntawm stainless hlau muaj feem xyuam rau lawv.
"Stainless steel" yog lus Askiv version ntawm "stainless steel" hauv lus Askiv, thiab siv hauv Japanese. Kev txhais ncaj qha yog hlau tsis xeb, tab sis qhov tseeb qhov kev nkag siab tias steel tsis xeb yog qhov tseeb.
Tsis zoo li lub tshav kub-resistant steel abbreviated li SUH, lub hom phiaj ntawm stainless hlau (SUS) yog los txhim kho corrosion kuj nyob rau hauv chav tsev kub. Yog li ntawd, stainless hlau tsis muaj tshwj xeeb kub kuj. Txawm li cas los xij, qhov kub-tiv taus ntawm stainless hlau rods yog 700 degree -800 degree . Tshwj xeeb tshaj yog tsis txhob siv nyob rau hauv ib qho chaw siab tshaj 900 degree. Nws tau lees tias yuav tsum muaj tsawg kawg yog 500 degree, yog li nws muaj kev nyab xeeb hauv kev siv dav dav.
Ntawm no yog ib qho kev qhia txog qhov kub-resistant kub ntawm ntau yam stainless hlau.
Lub tshav kub tsis kam ntawm cov hlau yog xam los ntawm ntau yam, tab sis "heat-resistant kub" nyob rau hauv tsab xov xwm no yog hais txog lub tensile lub zog ntawm hlau nyob rau hauv high kub (700 degree rau 800 degree).
1. Austenite
Austenitic stainless hlau yog ib qho zoo sib npaug stainless hlau uas yog ib qho yooj yim rau txheej txheem thiab muaj zoo heev corrosion kuj. Ntxiv rau cov hlau zoo tib yam, nws kuj muaj chromium (rau corrosion kuj) thiab npib tsib xee (rau stabilizing hlau Cheebtsam).
Vim tias nws muaj ntau yam kev tiv thaiv corrosion, nws feem ntau siv los ua cov khoom siv rau cov khoom raug los nag thiab cua. Tshwj xeeb, springs, siv conveyors, factories, industrial furnaces, thiab lwm yam.
Txawm hais tias nws yog qhov kub-tiv taus, nws lub zog ntawm ferrite thiab martensite yog siab li 600 degree, tab sis nws yog qhov ruaj khov tshaj plaws piv rau lwm cov hlau stainless saum 600 degree.
2. Ferrite
Ferrite yog stainless hlau uas tsis muaj nickel. Txij li thaum nws tsis muaj nickel, nws tsis tuaj yeem tsim ib zaj duab xis uas tiv thaiv cov hlau nto. Txawm hais tias nws cov kev tiv thaiv corrosion thiab lub zog tsis zoo dua li lwm cov hlau stainless, nws tuaj yeem tsim tau ntawm tus nqi qis.
Txawm li cas los xij, nws muaj qhov tsis tshua muaj corrosion tsis kam ntawm cov hlau tsis muaj steel, yog li nws tuaj yeem siv rau ntau yam kev siv nrog rau cov khoom siv hauv chav ua noj. Tshwj xeeb, nws suav nrog cov khoom siv hauv tsev, bolts thiab txiv ntseej, khoom noj khoom haus thiab tsheb kauj vab rims.
Nws yog tus cwj pwm los ntawm cov hlau nplaum muaj zog, thiab cov khoom siv tuaj yeem txiav txim siab seb nws puas ua raws li cov hlau nplaum. Hais txog qhov kub ntawm qhov no, qhov kub tsis kam yog qhov siab nyob rau thaj tsam ntawm 300 degree txog 400 degree, tab sis poob qis dua 500 degree.
3. Martensite
Hom martensitic yog ib hom uas muaj cov yam ntxwv uas lub zog tuaj yeem txhim kho los ntawm kev quenching tom ntej. Hauv stainless hlau, nws muaj cov ntsiab lus carbon siab thiab cov ntsiab lus chromium tsawg.
Yog li ntawd, piv nrog rau lwm yam stainless hlau, nws muaj ib tug muaj pes tsawg leeg uas xam lub zog, thiab feem ntau yog siv nyob rau hauv cov khoom uas lub zog yog tseem ceeb tshaj corrosion kuj. Tshwj xeeb, nws suav nrog cov hniav, li qub, brakes, bearings thiab turbine hniav.
Hais txog qhov kub thiab txias, nws lub zog yog siab dua li lwm cov hlau tsis muaj steel hauv qab 500 degree, tab sis cov cua kub tsis kam poob qis ntawm qhov kub siab dua.
4. Cov nag lossis daus hardening
Cov nag lossis daus hardening hom yog hom stainless hlau uas nws hardness yog nce los ntawm tempering. Nws yog tus cwj pwm los ntawm kev siv cov khoom sib txuas sib txuas es tsis txhob siv cov carbides siv hauv cov hlau tsis zoo tib yam, thiab piv nrog rau lwm cov hlau tsis muaj steel, tus nqi siab dua vim qhov nce ntawm cov txheej txheem tsim khoom.
Txawm li cas los xij, vim nws qhov kev ua tau zoo, nws feem ntau siv los ua cov khoom siv rau cov khoom siv high-end. Tshwj xeeb, nws yog siv rau shafts, turbines, springs, ntsuas qhov chaw, thiab lwm yam.
Stainless hlau rods muaj dav daim ntawv thov kev cia siab thiab yog dav siv nyob rau hauv hardware thiab kitchenware, shipbuilding, petrochemical, machinery, tshuaj, zaub mov, hluav taws xob, lub zog, lub tsev kho kom zoo nkauj, nuclear zog, aerospace, tub rog thiab lwm yam lag luam! Cov khoom siv hauv dej hiav txwv, tshuaj lom neeg, xim, ntawv, oxalic acid, chiv thiab lwm yam khoom siv ntau lawm; khoom noj khoom haus kev lag luam, chaw ntug hiav txwv dej, hlua, CD rods, bolts, ceev. Vim tias nws yog cov khoom tsim los rau qhov kub thiab txias (tsuas yog qis dua 550 degree), nws qhov kub tsis kam tiv taus yog qis dua lwm cov hlau tsis muaj steel. Tshwj xeeb, nws qhia tau hais tias muaj zog ntawm qhov kub txog li 500 degree, tab sis poob qis tshaj qhov kub no.
