Hlau Ntshiab vs. 3SP Steel
Thaum nws los txog rau cov khoom siv hlau, cov hlau ntshiab thiab 3SP steel txhua tus muaj lawv cov khoom tshwj xeeb thiab kev siv. Hauv qab no yog kev sib piv ntawm cov hlau ntshiab thiab 3SP steel nyob rau hauv cov nqe lus ntawm lawv muaj pes tsawg leeg, khoom, thiab raug siv.
Hlau ntshiab
Cov hlau ntshiab, tseem hu ua wrought hlau lossis refined hlau, yog ib qho khoom siv nrog cov cim tshuaj Fe thiab atomic tooj 26. Nws muaj lub ntsej muag dawb-dawb thiab yog mos thiab ductile thaum nyob rau hauv nws daim ntawv ntshiab.
Kev sib xyaw:
Cov hlau ntshiab tsuas yog muaj cov hlau, nrog cov impurities tsawg.
Cov khoom:
Mos thiab ductile: Cov hlau ntshiab tuaj yeem khoov tau yooj yim, ncab, thiab ua rau ntau yam duab.
Zoo hluav taws xob thiab thermal conductivity: Nws ua hluav taws xob thiab cua sov zoo.
Tsawg zog thiab hardness: Vim nws purity, ntshiab hlau tsis muaj lub zog thiab hardness xav tau rau ntau daim ntaub ntawv.
Corrosion kuj: Nws yog qhov cuam tshuam rau corrosion thaum raug oxygen thiab dej.
Siv:
Cov hlau ntshiab feem ntau yog siv rau hauv kev siv hluav taws xob vim nws cov conductivity zoo heev.
Nws kuj tseem siv rau hauv kev tsim cov hlau wrought, uas feem ntau yog siv rau kev kho kom zoo nkauj vim nws txoj kev ua kom zoo thiab muaj peev xwm ua tau yooj yim cam khwb cia rau hauv cov qauv tsim.
3SP Hlau
3SP steel yog ib hom hlau tshwj xeeb uas yog alloyed nrog lwm cov ntsiab lus los txhim kho nws cov khoom siv kho tshuab. Txawm hais tias qhov tseeb muaj pes tsawg leeg yuav txawv nyob ntawm cov chaw tsim khoom thiab cov ntawv thov, 3SP steel feem ntau muaj cov pa roj carbon, silicon, phosphorus, sulfur, thiab tejzaum nws muaj lwm yam alloying.
Kev sib xyaw:
Cov muaj pes tsawg leeg ntawm 3SP steel muaj xws li hlau raws li lub hauv paus ntsiab lus, nrog ntxiv carbon, silicon, phosphorus, sulfur, thiab tej zaum lwm yam alloying ntsiab xws li manganese, chromium, npib tsib xee, thiab lwm yam, los txhim kho nws lub zog, hardness, thiab corrosion kuj.
Cov khoom:
Siab zog thiab hardness: Vim qhov sib ntxiv ntawm cov ntsiab lus alloying, 3SP steel muaj zog dua thiab hardness piv rau cov hlau ntshiab.
Zoo hnav tsis kam: Nws yog resistant rau hnav thiab tsim kua muag, ua rau nws haum rau daim ntaub ntawv uas muaj kev sib txhuam thiab puas.
Txhim kho corrosion kuj: Nyob ntawm cov ntsiab lus alloying ntxiv, 3SP steel yuav muaj kev tiv thaiv corrosion zoo dua li cov hlau ntshiab.
Weldability thiab machinability: 3SP steel feem ntau tuaj yeem welded thiab machined kom tau raws li cov kev cai tshwj xeeb.
Siv:
3SP steel feem ntau yog siv rau hauv kev tsim cov cuab yeej, tshuab qhov chaw, thiab cov khoom siv uas xav tau lub zog siab, hardness, thiab hnav tsis kam.
Nws kuj tseem siv rau hauv tsheb, aerospace, thiab kev tsim kho kev lag luam vim nws cov kav ntev thiab muaj peev xwm tiv taus huab cua.
