Pure Iron vs. 08AL Steel
Thaum nws los txog rau cov khoom siv hlau, cov hlau ntshiab thiab 08AL steel muaj lawv cov khoom tshwj xeeb thiab kev siv. Hauv qab no yog kev sib piv ntawm ob, qhia txog lawv qhov sib txawv thiab cov yam ntxwv tseem ceeb.
Hlau ntshiab:
Kev sib xyaw: Cov hlau ntshiab, raws li lub npe qhia, muaj feem ntau ntawm cov hlau (Fe) nrog cov impurities tsawg. Nws yog lub hauv paus ntawm cov hlau, tsis sib xyaw nrog lwm cov hlau lossis cov khoom.
Cov khoom: Cov hlau ntshiab yog cov mos mos thiab du, nrog lub zog tensile tsawg thiab hardness. Nws muaj hluav taws xob zoo thiab thermal conductivity. Vim nws cov softness, cov hlau ntshiab tsis yog feem ntau siv rau hauv cov qauv siv uas yuav tsum tau muaj zog thiab hardness.
Daim ntawv thov: Ntshiab hlau pom siv nyob rau hauv daim ntaub ntawv uas nws cov hluav taws xob conductivity thiab sib nqus khoom muaj nuj nqis. Piv txwv xws li hluav taws xob transformers, generators, thiab tej hom hlau nplaum.
08 AL hlau:
Kev sib xyaw: 08AL steel yog hom hlau uas tsis muaj cov pa roj carbon tsawg, muaj kwv yees li 0.08% carbon thiab me me ntawm alloying ntsiab xws li txhuas (Al), silicon (Si), thiab manganese (Mn). Cov ntsiab lus ntawm aluminium yog qhov tseem ceeb, vim nws pab kom deoxidize cov hlau thiab txhim kho nws cov machinability.
Cov khoom: 08AL steel paub txog nws cov machinability zoo, weldability, thiab formability. Nws muaj lub zog tensile nruab nrab thiab hardness, ua rau nws haum rau ntau yam kev siv uas yuav tsum tau muaj zog thiab durability yam tsis tas yuav tsum muaj siab hardness.
Daim ntawv thov: 08AL steel yog dav siv nyob rau hauv kev lag luam tsim rau cov khoom uas yuav tsum tau zoo machinability thiab weldability. Piv txwv xws li cov ncej, lub zog, thiab lwm yam khoom siv tshuab. Nws kuj tseem siv rau hauv kev siv tsheb thiab kev tsim kho qhov twg lub zog thiab kev siv nyiaj tau zoo yog qhov tseem ceeb rau kev txiav txim siab.
Kev sib piv:
Lub zog thiab Hardness: 08AL steel muaj zog thiab nyuaj dua li cov hlau ntshiab, vim nws cov ntsiab lus carbon thiab alloying. Qhov no ua rau 08AL steel zoo dua rau kev siv cov qauv thiab cov kabmob.
Machineability: 08AL steel yog yooj yim rau tshuab dua cov hlau ntshiab, ua tsaug rau nws cov ntsiab lus txhuas thiab lwm yam alloying ntsiab uas txhim kho nws cov machinability.
Nqi: Cov hlau ntshiab yuav kim dua li 08AL steel vim nws qhov tsis tshua muaj thiab cov ntawv tshwj xeeb. Txawm li cas los xij, tus nqi sib txawv tuaj yeem sib txawv nyob ntawm kev ua lag luam thiab kev muaj.
Daim ntawv thov: Thaum cov hlau ntshiab yog txwv rau cov kev siv tshwj xeeb xws li hluav taws xob hloov hluav taws xob thiab cov hlau nplaum, 08AL steel muaj ntau yam kev siv hauv kev tsim khoom, tsheb, thiab kev tsim kho kev lag luam.
