Pure Hlau vs. Carbon Steel
Thaum tshawb nrhiav cov khoom siv hlau, cov hlau ntshiab thiab cov hlau tsis huv muaj cov yam ntxwv thiab kev siv. Hauv qab no yog kev sib piv ntawm cov hlau ntshiab thiab carbon steel nyob rau hauv cov nqe lus ntawm lawv muaj pes tsawg leeg, khoom, thiab raug siv.
Hlau ntshiab
Cov hlau ntshiab, feem ntau hu ua hlau wrought lossis refined hlau, yog cov hlau uas muaj cov cim tshuaj Fe thiab atomic tooj 26.
Kev sib xyaw:
- Cov hlau ntshiab muaj feem ntau ntawm cov hlau, nrog cov impurities tsawg.
Cov khoom:
- Mos thiab ductile: Cov hlau ntshiab yog yooj yim khoov, ncab, thiab ua rau ntau yam duab.
- Zoo heev hluav taws xob thiab thermal conductivity: Nws ua hluav taws xob thiab cua sov zoo.
- Tsawg tensile lub zog thiab hardness: Nws purity ua rau nws tsis tshua muaj zog thiab nyuaj piv rau cov hlau alloyed.
- Yooj yim rau corrosion: Cov hlau ntshiab reacts nrog oxygen thiab dej, ua rau corrosion.
Siv:
- Cov hlau ntshiab pom daim ntawv thov hauv cov khoom siv hluav taws xob vim nws cov conductivity.
- Nws kuj yog siv nyob rau hauv cov hniav wrought hlauwork vim nws malleability thiab yooj yim ntawm casting intricate designs.
Carbon Steel
Cov pa roj carbon steel yog cov hlau alloy nrog cov pa roj carbon monoxide ua lub hauv paus alloying, feem ntau yog li ntawm 0.05% mus rau 2.1% cov ntsiab lus carbon. Cov ntsiab lus ntxiv xws li manganese, silicon, phosphorus, sulfur, thiab qee zaus lwm yam alloying ntsiab yuav tshwm sim.
Kev sib xyaw:
- Cov pa roj carbon steel muaj pes tsawg leeg suav nrog hlau ua lub hauv paus, nrog cov pa roj carbon raws li cov ntsiab lus alloying. Cov ntsiab lus carbon thiab muaj lwm cov ntsiab lus cuam tshuam nws cov khoom siv kho tshuab.
Cov khoom:
- High tensile zog thiab hardness: Carbon steel yog qhov muaj zog thiab nyuaj dua li cov hlau ntshiab.
- Zoo hnav tsis kam: Nws tiv taus hnav thiab tsim kua muag, ua rau nws haum rau cov ntawv thov uas muaj kev sib txhuam thiab puas.
- Nws txawv nyob rau hauv corrosion kuj: Raws li cov ntsiab lus carbon thiab alloying cov ntsiab lus, carbon steel tuaj yeem ua los ntawm cov hlau me me uas tsis tshua muaj corrosion tsis kam mus rau high-carbon steel nrog kev txhim kho corrosion los ntawm kev kho cua sov.
- Weldability thiab machinability: Carbon steel tuaj yeem welded thiab machined kom tau raws li cov kev cai tshwj xeeb.
Siv:
- Cov pa roj carbon steel yog dav siv hauv kev tsim cov cuab yeej, tshuab qhov chaw, thiab cov khoom siv vim nws lub zog thiab hardness.
- Nws kuj tseem siv rau hauv tsheb, kev tsim kho, thiab lwm yam kev lag luam uas kav ntev thiab kev ua haujlwm hauv kev ntxhov siab yog qhov tseem ceeb.
Xaus
Hauv cov ntsiab lus, cov hlau ntshiab thiab carbon steel muaj qhov sib txawv tseem ceeb hauv kev sib xyaw, cov khoom, thiab kev siv. Cov hlau ntshiab, ua cov hlau tseem ceeb hauv nws daim ntawv purest, yog mos, ductile, thiab ua hluav taws xob thiab cua sov zoo, ua rau nws haum rau hluav taws xob thiab kho kom zoo nkauj. Cov pa roj carbon steel, los ntawm kev sib ntxiv ntawm cov pa roj carbon monoxide thiab muaj peev xwm ua tau lwm yam alloying, muaj lub zog tensile siab, hardness, thiab hnav tsis kam, ua rau nws zoo tagnrho rau cov ntawv thov kom muaj zog thiab kev ua haujlwm nyob rau hauv huab cua. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb hauv kev xaiv cov khoom tsim nyog rau cov ntawv thov tshwj xeeb.
