Dab tsi yog steel thiab nws ua li cas?
Thaum Hlau yog alloyed nrog carbon thiab lwm yam khoom nws yog hu ua hlau.Lub resultant alloy muaj daim ntaub ntawv raws li lub ntsiab ntawm lub tsev, infrastructure, cuab yeej, nkoj, tsheb, tshuab, ntau yam khoom siv, thiab riam phom.Cov kev siv yog ntau heev vim steels siab tensile lub zog thiab kuj tsis tshua muaj nqi.
Leej twg nrhiav tau nws?
Cov piv txwv ntxov tshaj plaws ntawm cov hlau tau pom nyob rau hauv Qaib Cov Txwv thiab hnub rov qab mus rau 1800BC.Kev tsim cov hlau niaj hnub no tau rov qab los rau Sir Henry Bessemerof England uas tau tshawb pom ib txoj hauv kev tsim khoom peb ntim siab thiab tus nqi qis.
Jindalai Steel Group yog ib lub chaw tsim khoom & Exporter ntawm stainless hlau kauj / ntawv / phaj / sawb / yeeb nkab.
Qhov txawv ntawm Hlau thiab Hlau yog dab tsi?
Hlau yog ib qho tshwm sim tshwm sim nyob rau hauv cov xwm txheej hauv Iron Ore. Hlau yog cov khoom tseem ceeb ntawm Hlau, uas yog cov hlau alloy nrog lub ntsiab ntxiv ntawm Hlau.Hlau muaj zog dua Hlau, nrog zoo nro thiab compression zog.
Cov yam ntxwv ntawm steel yog dab tsi?
● Hlau muaj zog tensile siab
● Nws yog malleable - cia nws yooj yim zoo li
● Durability – cia cov hlau tiv thaiv sab nraud.
● Conductivity - nws yog qhov zoo ntawm kev ua cua sov thiab hluav taws xob, muaj txiaj ntsig zoo rau cookware thiab thaiv.
● Luster - steel muaj qhov ntxim nyiam, zoo nkauj zoo nkauj.
● Rust Resistance - qhov sib ntxiv ntawm ntau yam hauv cov feem pua ntawm qhov sib txawv tuaj yeem muab cov hlau hauv cov hlau tsis muaj steel nws muaj kev tiv thaiv corrosion siab.
Qhov twg muaj zog dua, Hlau lossis Titanium?
Thaum alloyed nrog lwm yam hlau xws li txhuas lossis vanadium, titanium alloy muaj zog dua li ntau hom hlau.Nyob rau hauv cov nqe lus ntawm sheer lub zog, qhov zoo tshaj plaws titanium alloys yeej tsawg mus rau nruab nrab qib stainless hlau.Txawm li cas los xij, qib siab tshaj plaws ntawm cov hlau tsis muaj zog muaj zog dua li cov titanium alloys.
Dab tsi yog 4 hom hlau?
(1) Carbon hlau
Carbon steels muaj Hlau, Carbon, thiab lwm yam alloying ntsiab xws li Manganese, Silicon, thiab tooj liab.
(2) Alloy hlau
Alloy steels muaj cov hlau alloy sib txawv hauv qhov sib txawv, uas ua rau hom hlau no haum rau cov kev siv tshwj xeeb.
(3) Stainless hlau
Txawm hais tias cov hlau tsis muaj steel muaj ntau cov hlau alloys, lawv feem ntau muaj 10-20 feem pua chromium, ua rau nws yog thawj alloying.Piv nrog rau lwm hom hlau, stainless hlau yog kwv yees li 200 npaug ntau dua rusting, tshwj xeeb tshaj yog cov hom uas muaj tsawg kawg yog 11 feem pua chromium.
(4) Cov cuab yeej steel
Cov hlau no yog alloyed ntawm qhov kub siab heev thiab feem ntau muaj cov hlau tawv xws li tungsten, cobalt, molybdenum, thiab vanadium.Txij li thaum lawv tsis yog tsuas yog kub resistant tab sis kuj ruaj, cov cuab yeej steel yog feem ntau siv rau txiav thiab drilling khoom.
Qib zog tshaj yog dab tsi?
SUS 440- uas yog qib siab dua ntawm cov hlau cutlery uas muaj feem pua ntawm cov pa roj carbon ntau dua, muaj kev tuav tuav zoo dua thaum kho cua sov kom zoo.Nws tuaj yeem hardened rau kwv yees li Rockwell 58 hardness, ua rau nws yog ib qho nyuaj tshaj plaws stainless hlau.
Vim li cas ho tsis steel term ua hlau?
Ib qho ntawm cov lus nug uas nquag nug txog cov hlau yog vim li cas cov hlau tsis yog hlau?Hlau, ua ib qho alloy thiab yog li ntawd tsis yog cov khoom ntshiab, tsis yog technically hlau tab sis muaj kev hloov pauv ntawm ib qho.Nws yog ib feem ntawm cov hlau, hlau, tab sis vim nws kuj muaj cov pa roj carbon uas tsis yog hlau hauv nws cov tshuaj pleev ib ce, nws tsis yog cov hlau ntshiab.
Hom twg siv tshaj plaws?
304 Stainless Hlau lossis SUS 304 qib siab tshaj plaws;Classic 18/8 (18% chromium, 8% nickel) stainless hlau.Sab nraum Teb Chaws Asmeskas, nws feem ntau hu ua "A2 stainless hlau", raws li ISO 3506 (tsis yog yuav tsum tsis meej pem nrog A2 cuab yeej hlau)
Puas yog steel yog cov khoom siv ruaj khov?
Hlau yog cov khoom siv tshwj xeeb ruaj khov vim tias thaum nws tsim nws tuaj yeem siv tau, ua hlau, mus ib txhis.Hlau yog infinitely recycled, yog li kev nqis peev hauv kev ua hlau tsis tau nkim thiab tuaj yeem ua lag luam los ntawm cov tiam tom ntej.
