Hlau tuaj nyob rau hauv ntau yam duab thiab yog ib qho tseem ceeb nyob rau hauv ntau yam kev lag luam. Cov khoom siv kho tshuab ntawm txhua daim ntawv, uas yog qhov tshwj xeeb thiab tsim nyog rau kev siv ntau yam, yog qhov sib txawv; carbon steels thiab alloy steels yog cov ntaub ntawv nrov tshaj plaws. Txawm li cas los xij, cov kev sib txawv no yog txhua yam nyob rau hauv cov qauv ntawm cov hlau.
Ntawm nws cov tub ntxhais, steel feem ntau yog sib xyaw ntawm hlau nrog carbon ntxiv rau nws. Nws tsis yog technically ib qho hlau vim hais tias hlau yog cov khoom uas tshwm sim ib txwm muaj, xws li tooj liab lossis txhuas. Txawm hais tias nyob rau hauv nws daim ntawv tseem ceeb tshaj plaws, hlau yog ib qho kev sib xyaw ua ke ntawm ntau lub ntsiab lus thiab / lossis cov khoom. Txawm hais tias hlau yog ib yam khoom, nws yuav tsum tau carbon hloov los ntawm hlau mus rau hlau.
Lub luag haujlwm ntawm Hlau hauv Hlau
Tag nrho cov hlau yog tsim los ntawm cov hlau, uas yog lub hauv paus rau tag nrho lwm cov ntaub ntawv ntawm steel nyob ntawm seb lwm yam khoom ntxiv rau nws. Thaum lub sij hawm tsim cov txheej txheem, nws imparts nws lub zog thiab tsis kam mus rau tshav kub thiab corrosion rau hlau.
Cov kauj ruam tseem ceeb hauv kev tig hlau mus rau hauv cov hlau yog purging impurities, kho cov pa roj carbon concentration, thiab ntxiv cov khoom los ua ntau hom hlau.
Lub luag haujlwm ntawm Carbon hauv Steel
Cov pa roj carbon monoxide yog cov khoom uas tswj cov hardness thiab ductility ntawm steel. Qhov nyuaj nws yog los tsim cov hlau, qhov siab dua cov carbon concentration. Hlau yog mos thiab pliable ntawm nws tus kheej; nws tsis siv ntau carbon los hloov qhov ntawd.
Cov ntsiab lus carbon
Cov pa roj carbon steel tau muab faib ua peb pawg: siab, nruab nrab, thiab qis. High-carbon steel tsuas muaj cov ntsiab lus carbon ntawm ib ncig ntawm 0.60% - 1%; cov hlau uas muaj cov ntsiab lus carbon siab dua 1% yog qhov hnyav heev, thiab nws tsuas yog siv 2% - 3% cov ntsiab lus carbon los hloov cov hlau mus rau hauv cov hlau cam. High-carbon steel feem ntau yog siv rau cutlery thiab daim ntaub ntawv uas yuav tsum tau ntse, tawv npoo.
Nruab nrab-carbon steel nta qhov twg los ntawm 0.30% - 0.60% carbon. Cov hlau no tsis muaj zog lossis nyuaj li cov pa roj carbon ntau, tab sis nws ua haujlwm tau ntau dua. Nws yog siv los ua tsheb ciav hlau log, tsheb ciav hlau lem, machinery thiab automotive qhov chaw, thiab daim ntaub ntawv uas yuav tsum tau muaj zog, toughness, thiab dlej machinability.
Tsawg-carbon steel muaj cov ntsiab lus carbon tsawg dua 0.30% thiab feem ntau yuav tsum tau carburized ua ntej kev kho cua sov. Cov pa roj carbon molecules tau ntxiv thaum lub sijhawm carburization txheej txheem, ua rau saum npoo los ua ib qho tawv "daim tawv nqaij" thiab "cov ntaub ntawv". Qhov no yog lub hauv paus ntawm lub tswv yim ntawm case hardening. Cov hlau no tsim nyog rau cov fasteners xws li clevis pins thiab cov yuam sij tshuab vim tias lawv ua tau zoo nyob rau hauv cov xwm txheej uas yuav tsum tau ua kom txias los yog ua haujlwm.
Carbon Steel vs Steel Alloy: Qhov txawv
Hlau nws tus kheej yog ib qho hlau vim nws yog kev sib xyaw ntawm ntau yam (hlau thiab carbon). Tab sis qhov sib tov no-uas yog lub npe hu ua carbon steel-yog qhov tseem ceeb tshaj plaws ntawm cov hlau; nws yuav muaj cov kab ntawm lwm cov ntsiab lus, tab sis tsis txaus kom paub qhov txawv.
Cov hlau alloys suav nrog cov khoom ntxiv xws li sulfur, manganese, npib tsib xee, chromium, molybdenum, thiab lwm yam alloying ntsiab rau cov qauv ntawm cov hlau. Cov no ntxiv rau cov hlau txhawm rau hloov kho, nce, lossis txo nws cov machinability, tensile zog, hardness, tsis kam mus corrosion, thiab lwm yam zoo.
Hauv cov ntsiab lus yooj yim, ntawm no yog qhov txawv ntawm carbon steel thiab steel alloy:
Carbon steel=hlau + carbon
Hlau alloy=hlau + carbon + lwm yam khoom
Nco ntsoov tias cov khoom zoo uas tau teev tseg thaum nyeem txog ntau yam carbon thiab alloy steel yog kwv yees thiab yuav tsum tsuas yog siv raws li kev siv dav dav. Txhawm rau kom paub meej qhov zoo ntawm cov khoom koj xav tau thiab cov kev qhia tshwj xeeb uas xav tau rau koj daim ntawv thov, koj yuav tsum ua raws li koj tus kheej txoj kev kawm.
Carbon Steel yog dab tsi?
Carbon steel yog cov hlau uas tso siab rau cov ntsiab lus carbon rau nws cov qauv. Lub ntsiab hardening tivthaiv uas tswj cov degree ntawm hardness los yog lub zog attained thaum lub sij hawm quenching yog carbon. Raws li steel cov ntsiab lus carbon nce, yog li ua nws lub zog tensile, hardness, thiab tsis kam hnav thiab puas. Tsis tas li ntawd, nws tuaj yeem txo qhov toughness, machinability, thiab ductility.
Alloy Steel yog dab tsi?
Alloy steel yog ib hom hlau nrog alloying ntsiab lus uas tsis yog carbon ntxiv los txhim kho nws cov khoom. Qee qhov sib ntxiv rau cov hlau alloy muaj xws li: chromium, cobalt, columbium, molybdenum, manganese, npib tsib xee, titanium, tungsten, silicon, thiab vanadium.

Cov pa roj carbon steel thiab hlau alloys yog siv los ua ntau yam ntawm cov fasteners siv nyob rau hauv kev siv ntau yam hauv kev lag luam tsheb, kev ua liaj ua teb, khoom noj khoom haus thiab kev kho mob, thiab lwm yam. Cov pa roj carbon steel ntawm nws tus kheej muaj ntau yam khoom nyob ntawm nws cov pa roj carbon thiab hlau cov ntsiab lus piv, thaum lub zog ntawm cov hlau alloy yog cuam tshuam los ntawm cov ntsiab lus sib txawv ntxiv rau carbon steel puag. Qhov no tsim cov hlau sib txawv nrog cov txheej txheem sib txawv.
