Lub tswv yim ntawm steel: Hlau yog ib qho hlau alloy ntawm hlau, carbon, thiab ib tug me me ntawm lwm yam ntsiab.Hlau yog ib qho ingot, billet, los yog hlau uas tau nias-ua haujlwm rau hauv cov duab, qhov loj me, thiab cov khoom peb xav tau.Hlau yog cov khoom siv tseem ceeb rau kev tsim kho hauv tebchaws thiab kev ua tiav ntawm plaub qhov kev hloov kho tshiab.Nws yog dav siv thiab muaj ntau yam.Raws li qhov sib txawv ntawm qhov sib txawv, nws feem ntau muab faib ua plaub pawg: profiles, phaj, kav dej, thiab cov khoom hlau.Txhawm rau pab txhawb kev tsim khoom thiab xaj cov khoom siv steel thiab ua haujlwm zoo hauv kev ua haujlwm thiab kev tswj hwm, nws tau muab faib ua cov tsheb ciav hlau hnyav, lub teeb rail, loj seem steel, nruab nrab seem steel, me me steel, txias-tsim seem steel, zoo. seem steel, hlau pas nrig, nruab nrab thiab tuab steel phaj, nyias steel phaj, hluav taws xob silicon steel ntawv, sawb hlau, tsis muaj Seam steel yeeb nkab, welded steel yeeb nkab, hlau khoom, thiab lwm yam.
Hlau yog ib qho hlau hlau, carbon, thiab me me ntawm lwm cov ntsiab lus.Stainless hlau los yog corrosion-resistant alloy steel nrog 10.5% los yog ntau dua chromium-kub cov ntsiab lus yog ib lo lus generic rau hom hlau no.Nws yuav tsum tau nco ntsoov tias stainless hlau tsis txhais hais tias cov hlau yuav tsis xeb los yog corrode, tab sis tsuas yog hais tias nws yog ntau resistant rau corrosion tshaj alloys uas tsis muaj chromium.Ntxiv nrog rau cov hlau chromium, lwm yam hlau xws li npib tsib xee, molybdenum, vanadium, thiab lwm yam kuj tuaj yeem muab ntxiv rau cov hlau los hloov cov khoom ntawm cov hlau alloy, yog li ua cov hlau tsis muaj cov qib sib txawv thiab cov khoom.Kev ua tib zoo xaiv cov riam ua los ntawm cov hlau tsis muaj steel nrog cov khoom tsim nyog tshaj plaws, nyob ntawm lub hom phiaj thiab qhov chaw ntawm daim ntawv thov, yog qhov tseem ceeb rau kev txhim kho kev ua tau zoo thiab qhov tshwm sim ntawm kev ua tiav rau ib txoj haujlwm.Qhov zoo ntawm cov hlau sib txawv hauv cov riam.Yooj yim muab: Hlau yog ib qho hlau alloy ntawm hlau thiab carbon.Lwm cov khoom xyaw muaj nyob rau qhov sib txawv ntawm cov khoom ntawm cov hlau.Cov hlau tseem ceeb tau teev tseg hauv qab no hauv cov ntawv sau, thiab lawv muaj cov khoom xyaw hauv qab no:
Carbon - Tam sim no nyob rau hauv tag nrho cov hlau thiab yog ib qho tseem ceeb hardening lub caij.Txhawm rau pab ua kom lub zog ntawm cov hlau, peb feem ntau xav tau riam-qib steel kom muaj ntau tshaj 0.5% carbon, kuj muaj cov pa roj carbon ntau.
Chromium - Ua kom hnav tsis kam, hardness, thiab tseem ceeb tshaj plaws corrosion kuj, nrog ntau dua 13% suav tias yog stainless hlau.Txawm hais tias nws lub npe, tag nrho cov hlau yuav xeb yog tias tsis tswj xyuas kom zoo.
Manganese (Manganese) - ib qho tseem ceeb ntawm cov khoom uas ua rau kev tsim cov qauv kev ntxhib los mos, thiab ntxiv dag zog, lub zog, thiab hnav tsis kam.Sab hauv deoxidation ntawm hlau thaum kho cua sov thiab crimping yog pom nyob rau hauv feem ntau riam thiab shear steels tshwj tsis yog A-2, L-6, thiab CPM 420V.
Molybdenum (Molybdenum) - carbonizing tus neeg sawv cev, tiv thaiv cov hlau los ntawm nkig, tuav steel lub zog ntawm qhov kub thiab txias, tshwm sim nyob rau hauv ntau daim hlau, cua hardening steels (xws li A-2, ATS-34) ib txwm muaj 1% los yog ntau dua Molybdenum yog li. lawv tuaj yeem ua rau saum huab cua.
Nickle - tuav lub zog, corrosion kuj, thiab toughness.Muaj nyob rau hauv L-6\AUS-6 thiab AUS-8.
Silicon - Pab kom muaj zog.Zoo li manganese, silicon yog siv los tswj lub zog ntawm cov hlau thaum nws tsim khoom.
Tungsten (Tungsten) - Txhim kho kev puas tsuaj.Kev sib xyaw ntawm tungsten thiab ib qho kev faib ua feem ntawm chromium los yog manganese yog siv los ua cov hlau kub ceev.Ib tug loj npaum li cas ntawm tungsten muaj nyob rau hauv high-ceev steel M-2.
Vanadium - Txhim kho hnav tsis kam thiab ductility.Ib tug carbide ntawm vanadium yog siv los ua cov hlau striped.Vanadium muaj nyob rau hauv ntau hom hlau, ntawm cov uas M-2, Vascowear, CPM T440V, thiab 420VA muaj ib tug loj npaum li cas ntawm vanadium.Qhov sib txawv loj tshaj plaws ntawm BG-42 thiab ATS-34 yog qhov qub muaj vanadium.
