Hlau yog kom meej meej siv nyob rau hauv ib tug ntau yam ntawm industries thiab daim ntaub ntawv, txhua yam uas yuav tsum tau sib txawv rau covmechanical zog ntawm cov hlauhauv nqe lus nug. Nyob ntawm kev siv, qee cov hlau yuav tsum ua kom zoo thiab ua kom zoo, thaum lwm tus xav tau cov hlau tawv uas muaj zog corrosion kuj. Tseem muaj lwm daim ntawv thov hu rau ntau yam khoom vaj khoom tsev ua ke.
Txhawm rau ua kom tau raws li qhov xav tau ntau yam no, ntau hom hlau yog tsim los kom muaj qhov tshwj xeeb. Hlau, txhuas, tooj dag, tooj liab, npib tsib xee, thiab cov npe ntev ntawm lwm cov ntaub ntawv pom tseeb muaj. Koj tsis yog, txawm li cas los xij, txwv rau ntau pawg no. Cov hlau kuj tuaj yeem ua alloyed, lossis ua ke nrog lwm cov hlau lossis cov khoom siv, los tsim cov ntaub ntawv nrog cov khoom tshiab lossis txhim kho zoo.
Raws li cov hlau yog ib qho ntawm cov hlau feem ntau, tsab xov xwm no yuav mloog zoo rau cov hlau alloy yog dab tsi, cov ntsiab lus twg tuaj yeem muab ntxiv rau lawv, thiab qee qhov nrov tshaj plaws ntawm cov hlau alloys.
Alloy Steel yog dab tsi?
Yuav kom nkag siab tias cov hlau alloy yog dab tsi, nws yog ib qho tseem ceeb kom paub tias cov ntsiab lus yog dab tsihlau alloy thiabhlautxhais tau tias ntawm lawv tus kheej.
Alloyyog qhov sib xyaw ntawm ob lossis ntau lub ntsiab lus uas, thaum sib xyaw, khaws cov khoom siv hlau. Nws tuaj yeem muab ntau yam hlau sib txawv ua ke lossis sib txuas cov hlau nrog cov hlau tsis muaj hlau xws li phosphorous lossis carbon. Ntxiv nrog rau cov khoom siv alloying 'inherent qualities, qhov sib tov confers tshwj xeeb txhua yam zoo xws li harderness, siab tensile zog, thiab kuj rau corrosion.
Hlauyog ib qho kev sib xyaw ntawm cov hlau thiab cov pa roj carbon monoxide nrog tsuas yog cov lej ntawm lwm cov ntsiab lus. Technically, carbon steel yog ib qho hlau vim nws sib tov ob lub ntsiab lus, tab sis feem ntau nws yog hu ua carbon steel - muaj ib tugQhov sib txawv ntawm carbon steel thiab steel alloys. Nws cov pleev yog feem ntau hlau, tab sis cov ntsiab lus carbon yog qhov tseem ceeb ntawm cov qauv.
Hlau tau txais lub zog, hardness, thiab hnav tsis kam raws li nws cov ntsiab lus carbon nce, tab sis nws kuj poob ductility, machinability, thiab weldability vim li ntawd. Cov hlau alloy yog cov hlau uas sib xyaw ua ke ntawm kev sib xyaw nrog cov qauv ntawm cov hlau. Lawv tsim ntau hom hlau nrog ntxiv lossis hloov kho cov khoom zoo thaum ntxiv rau cov pa roj carbon steel.
Common Hom ntawm Alloy Steel
Muaj ntau ntau yam hlau alloys muaj, tab sis cia peb ua tib zoo saib ntawm ob peb hom steel alloys siv los tsim cov fasteners thiab tshuab cov khoom xws lidowel pins.
52100 alloy hlauyog ib tug high-carbon, chromium-alloy steel. Nws muaj pes tsawg leeg suav nrog kwv yees li 1.0% carbon, 1.4% chromium, thiab me me ntawm manganese, silicon, thiab lwm yam kab kawm. 52100 steel yog qhov zoo heev rau nws qhov tshwj xeeb hnav tsis kam thiab muaj peev xwm tswj tau qhov ntse ntse. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv qhov twg hardness thiab abrasion kuj tseem ceeb, xws li bearings,koob rollersthiabdowel pins.
1018 Hlauyog ntau yam ntawm cov pa roj carbon tsawg, tseem hu ua me me steel. Nws muaj tsawg dua ntawm lwm cov ntsiab lus thiab qhov siab tshaj ntawm 0.2% carbon. Nws yog dav siv nyob rau hauv ntau daim ntawv thov thiab muab ib tug tshwj xeeb tshuav nyiaj li cas ntawm lub zog, ductility, thiab machinability. Carburization yog ib txoj kev ntawm cov ntaub ntawv-hardening low-carbon steel. Nws yog siv los tsim ntau homdowel pinsthiab rivet txiv ntoo, thiab lwm yam.
1144 Steelyog nruab nrab-carbon steel nrog nruab nrab ntawm 0.4 thiab 0.8% carbon, ntxiv rau me me ntawm manganese. Nws yog ib qho yooj yim rau tshuab thiab nws tuaj yeem raug kho kom sov kom nws cov hardness.
304 thiab 316 Stainless hlauyog austenitic steels uas muaj chromium thiab nickel. 316 stainless hlau kuj muaj molybdenum, uas txhim kho nws cov kev tiv thaiv rau qee hom kev xeb. Cov hlau tsis muaj hlau no tau siv dav hauv cov ntsia hlau thiab lwm yam kev tiv thaiv corrosion-resistant fasteners nyiamtus pin, qee qhov lifting thiab rigging hardware, thiab hose clamps.
410/416 Stainless hlauyog martensitic steels uas muaj nyob nruab nrab ntawm 11 thiab 12% chromium nrog rau lwm yam xws li silicon, nickel, sulfur. 410 yog tus nqi qis, kub kho tau qib siv rau cutlery, cov ntxaij vab tshaus,caij nplooj ntoos hlav pins, turbine blades, thiab lwm yam kev siv tsis zoo corrosion. 416 muaj cov machinability zoo heev thiab qee cov hlau nplaum, ua rau nws haum raudowel pins, txiv ntseej, bolts, valve trim, thiab lwm yam fasteners.
Cov no tsuas yog ib feem me me ntawm ntau cov hlau alloys uas muaj.
Wenqi siv cov hlau alloy, stainless hlau, thiab ntau lwm yam hlau hauv pebfasteners, bearing rollers, driveline qhov chaw, thiab ntau dua. Kawm paub txog pebkev cai tsim muaj peev xwm, tsis txhob yig tau tiv tauj nrog peb Pab Pawg Muag Khoom kom paub ntau ntxiv.
