Hlau yog dab tsi thiab nws ua li cas?
Thaum Hlau yog alloyed nrog carbon thiab lwm yam ntsiab lus nws hu ua hlau. Cov alloy tshwm sim muaj daim ntawv thov ua lub ntsiab Cheebtsam ntawm cov tsev, infrastructure, cov cuab yeej, nkoj, tsheb, tshuab, ntau yam khoom siv, thiab riam phom. Kev siv yog ntau yam vim yog cov hlau muaj lub zog tensile siab thiab tus nqi qis.
Leej twg nrhiav tau nws?
Cov piv txwv thawj zaug ntawm cov hlau tau raug tshawb pom hauv tebchaws Turkey thiab hnub rov qab mus rau 1800BC. Kev tsim cov hlau niaj hnub no tau rov qab mus rau Sir Henry Bessemer ntawm tebchaws Askiv uas tau tshawb pom txoj hauv kev tsim khoom uas muaj ntau thiab pheej yig.
Jindalai Steel Group yog ib lub tuam txhab tsim khoom thiab xa tawm cov hlau tsis xeb coil/sheet/plate/strip/yeeb nkab.
Qhov txawv ntawm Hlau thiab Hlau yog dab tsi?
Hlau yog ib yam khoom uas muaj nyob hauv xwm txheej. Hlau yog ib qho tseem ceeb ntawm cov hlau, uas yog ib qho sib xyaw ntawm Hlau nrog rau ntxiv cov hlau tseem ceeb. Hlau muaj zog dua Hlau, nrog rau kev nruj thiab kev nias zoo dua.
Cov yam ntxwv ntawm hlau yog dab tsi?
● Hlau muaj zog Tensile siab
● Nws yooj yim hloov pauv - ua rau nws yooj yim hloov pauv
● Kev ruaj khov - tso cai rau cov hlau kom tiv taus cov zog sab nraud.
● Kev coj hluav taws xob - nws zoo ntawm kev coj cua sov thiab hluav taws xob, muaj txiaj ntsig zoo rau cov khoom siv ua noj thiab cov xov hlau.
● Luster - hlau muaj ib qho zoo nkauj, silvery tsos.
● Tiv Thaiv Xeb - qhov ntxiv ntawm ntau yam khoom sib txawv ua rau cov hlau stainless hlau muaj zog tiv thaiv xeb siab.
Qhov twg muaj zog dua, Hlau lossis Titanium?
Thaum sib xyaw nrog lwm cov hlau xws li txhuas lossis vanadium, titanium alloy muaj zog dua li ntau hom hlau. Hais txog lub zog, cov titanium alloys zoo tshaj plaws yeej cov hlau tsis xeb qib qis mus rau qib nruab nrab. Txawm li cas los xij, cov hlau tsis xeb qib siab tshaj plaws muaj zog dua li titanium alloys.
4 hom hlau yog dab tsi?
(1) Cov Hlau Carbon
Cov hlau carbon muaj hlau, carbon, thiab lwm yam khoom sib xyaw xws li Manganese, Silicon, thiab Tooj.
(2) Cov Hlau Sib Xyaws
Cov hlau sib xyaw muaj cov hlau sib xyaw ua ke hauv ntau qhov sib txawv, uas ua rau hom hlau no haum rau cov ntawv thov tshwj xeeb.
(3) Cov Hlau Tsis Xeb
Txawm hais tias cov hlau tsis xeb muaj ntau yam hlau sib xyaw, feem ntau lawv muaj 10-20 feem pua chromium, ua rau nws yog cov khoom sib xyaw tseem ceeb. Piv rau lwm hom hlau, cov hlau tsis xeb muaj kwv yees li 200 npaug ntau dua rau kev xeb, tshwj xeeb tshaj yog cov hom uas muaj tsawg kawg 11 feem pua chromium.
(4) Cov Hlau Cuab Yeej
Cov hlau no yog ua los ntawm cov hlau sib xyaw ua ke ntawm qhov kub siab heev thiab feem ntau muaj cov hlau tawv xws li tungsten, cobalt, molybdenum, thiab vanadium. Vim tias lawv tsis tsuas yog tiv taus cua sov xwb tab sis kuj ruaj khov, cov hlau siv rau kev txiav thiab khawb cov khoom siv.
Qib twg muaj zog tshaj?
SUS 440– uas yog cov hlau txiav riam qib siab dua uas muaj feem pua ntawm cov pa roj carbon ntau dua, nws muaj kev tuav zoo dua thaum kho cua sov kom zoo. Nws tuaj yeem ua kom tawv txog li Rockwell 58, ua rau nws yog ib qho ntawm cov hlau tsis xeb nyuaj tshaj plaws.
Vim li cas hlau tsis hu ua hlau?
Ib qho ntawm cov lus nug uas neeg nug ntau tshaj plaws txog hlau yog vim li cas hlau thiaj tsis raug suav tias yog hlau? Hlau, vim yog ib yam khoom sib xyaw thiab tsis yog ib yam khoom ntshiab, tsis yog hlau tab sis yog ib qho sib txawv ntawm ib yam. Nws muaj ib feem ua los ntawm hlau, hlau, tab sis vim nws kuj muaj cov pa roj carbon uas tsis yog hlau hauv nws cov tshuaj lom neeg, nws tsis yog hlau ntshiab.
Hom twg siv ntau tshaj plaws?
304 Stainless Steel los yog SUS 304 yog qib feem ntau; cov hlau stainless 18/8 (18% chromium, 8% nickel). Sab nraum Teb Chaws Asmeskas, nws feem ntau hu ua "A2 stainless steel", raws li ISO 3506 (tsis txhob yuam kev nrog A2 tool steel)
Puas yog hlau yog ib yam khoom siv ruaj khov?
Hlau yog ib yam khoom siv uas ruaj khov tshwj xeeb vim tias thaum twg ua tiav lawm ces siv tau ua hlau mus ib txhis. Hlau rov ua dua tshiab tau ntau zaus, yog li ntawd, kev nqis peev hauv kev ua hlau yeej tsis nkim thiab cov tiam neeg tom ntej tuaj yeem siv tau.
