Dab tsi yog cov hlau thiab nws tau ua li cas?
Thaum hlau yog txuam nrog carbon thiab lwm cov khoom nws yog hu ua hlau. Lub txiaj ntsig tau muaj cov ntawv thov raws li cov tuam tsev tseem ceeb, cov cuab yeej siv, cov khoom lag luam, cov khoom siv, thiab riam phom. Cov siv yog myriad vim yog cov hlau loj tensile lub zog thiab tus nqi qis.
Leej twg nrhiav tau nws?
Cov qauv ua ntej ntawm cov hlau tau pom hauv Turkey thiab hnub rov qab rau 1800bc. Cov khoom lag luam niaj hnub ntawm cov hnub hlau rov qab rov qab mus rau Sir Henry Bessemerof England uas nrhiav tau ib hom kev tsim khoom ntawm ntau lawm peb cov nqi qis thiab tus nqi tsawg.
Jindalai Steel Group yog ib qho chaw tsim khoom & cov khoom lag luam ntawm cov hlau stainless hlau chev roj / ntawv / tawv / strip / yeeb nkab.
Qhov sib txawv ntawm cov hlau thiab hlau yog dab tsi?
Hlau yog ib qho tshwm sim ib txwm muaj nyob hauv cov ore. Hlau yog lub ntsiab tivthaiv ntawm cov hlau, uas yog ib qho alloy ntawm cov hlau nrog cov hlau txuas ntxiv. Cov hlau muaj zog dua li hlau, nrog cov khoom muaj zog zoo dua thiab cov khoom siv compression.
Dab tsi yog cov khoom ntawm cov hlau?
● Cov hlau muaj lub zog siab tensile
● Nws yog malleable - tso cai nws yuav yooj yim puab
● Durability - Tso cai rau cov hlau kom tiv thaiv sab nraud.
● Kev ua - nws yog qhov zoo ntawm kev ua cov cua sov thiab hluav taws xob, muaj txiaj ntsig rau cov cookware thiab xaim.
● Luster - Hlau muaj qhov txaus nyiam, silvery tsos.
● Rust kuj - ntxiv rau ntau yam hauv cov sib txawv no tuaj yeem muab cov hlau hauv daim ntawv ntawm stainless hlau nws yog siab corrosion tsis kam.
Uas muaj zog dua, steel lossis titanium?
Thaum txuam nrog lwm cov hlau xws li txhuas lossis vanadium, titanium alloy muaj zog dua ntau hom hlau. Nyob rau hauv cov nqe lus ntawm sheer lub zog, qhov zoo tshaj plaws titanium alloys tuav qis rau cov hlau me me stainless hlau. Txawm li cas los xij, qib siab ntawm stainless hlau muaj zog dua titanium alloys.
4 hom hlau yog dab tsi?
(1) Cov hlau carbon
Carbon steels muaj hlau, carbon, thiab lwm yam alloying cov xws li manganese, silicon, thiab tooj.
(2) Alloy Steel
Alloy Steels muaj cov hlau sib xyaw ua ke hauv cov sib txawv, uas ua rau hom steel tsim rau cov kev siv.
(3) Stainless hlau
Txawm hais tias stainless hlau muaj ntawm ob peb hlau alloys, lawv feem ntau muaj 10-20 feem pua chromium, ua rau nws thawj kev sib dhos. Piv rau lwm cov qauv ntawm cov hlau, stainless hlau yog kwv yees li 200 lub sij hawm tiv taus xeb, tshwj xeeb tshaj yog cov hom uas muaj tsawg kawg yog 11 feem pua chromium.
(4) Cov Hlau Cuab Yeej
Hom hlau no tau sib txuam ntawm cov kub heev thiab feem ntau muaj cov hlau ua kom zoo li tungsten, cobalt, molybdenum, thiab vanadium. Txij li thaum lawv tsis yog tsuas yog kub tiv thaiv tab sis kuj ruaj khov, cov cuab yeej siv hlau feem ntau siv rau cov khoom siv drilling.
Dab tsi yog qib muaj zog tshaj?
Sus 440- Uas yog qib siab dua ntawm cov hlau cutlery uas muaj feem pua siab dua ntawm cov pa roj carbon ntau, muaj cov ntug zoo dua thaum muaj kev kho mob kom zoo. Nws tuaj yeem yog qhov tawv me rau kwv yees li Rockwell 58 Hardness, ua rau nws yog ib qho nyuaj stainless hlau.
Vim li cas tsis yog steel ua tsis raug ua hlau?
Ib qho ntawm feem ntau nug cov lus nug txog cov hlau yog vim li cas tsis yog steel classed raws li hlau? Hlau, ua ib qho alloy thiab yog li ntawd tsis yog ib qho ntshiab, tsis yog cov hlau txuas nrog ib qho hloov pauv. Nws yog ib feem ntawm cov hlau, hlau, tab sis vim nws tseem muaj cov pa roj carbon, hauv nws cov tshuaj ua kom zoo nkauj, nws tsis yog hlau ntshiab.
Qhov twg yog hom feem ntau siv?
304 stainless hlau lossis sus 304 feem ntau yog qib; Lub classic 18/8 (18% chromium, 8% npib tsib xee) stainless hlau. Sab nraud ntawm Asmeskas, nws yog feem ntau hu ua "A2 stainless hlau", raws li ISO 3506 (tsis yog yuav tsum tau tsis meej pem nrog A2 tuam hlau)
Puas yog cov hlau ib qho khoom siv nyob ntev?
Cov hlau yog cov khoom siv tsis sib xws tau vim tias thaum nws tau tsim nws tuaj yeem siv, ua hlau, tas mus li. Cov hlau yog infinitely rov ua dua, yog li kev nqis peev hauv kev ua cov hlau tsis nkim sij hawm thiab tuaj yeem tsim nyog rau cov tiam tom ntej.
Qee cov ntsiab lus nthuav txog cov hlau
● Thaum cov hlau yog cov khoom siv muaj zog ntawm nws tus kheej, cov hlau tuaj yeem yog 1000 zaus muaj zog dua li hlau.
● Roting ntawm steel qeeb caum los yog txawm nres tsis puv thaum muaj hluav taws xob tam sim no dhau los ntawm cov hlau. Qhov no yog hu ua Cathodic tiv thaiv thiab siv rau Pipelines, nkoj, thiab cov hlau ua pob zeb.
