Science qab steel

Hlau yog qhov tshwm sim ntawm kev ntxiv carbon rau hlau.

Hauv lwm lo lus, nws zoo li kev sib xyaw ua ke ntawm ob lub ntsiab lus uas tsim ib yam dab tsi zoo dua! 

Thaum nws los txog rau steel, nws yog txhua yam hais txog cov ntsiab lus carbon. Ntawm no yog ib tug ceev ceev:

• Hlau: Muaj 0 - 0.04% carbon
• Hlau: muaj 0.04 - 2% carbon
• High Carbon Steel: Muaj ntau tshaj 0.7% carbon

Qhov siab dua cov ntsiab lus carbon, qhov nyuaj thiab muaj zog steel yog.

Thaum nws los txog rau steel, nws tsis yog ib qho loj-haum-txhua yam kev sib cog lus.

Muaj ntau ntau hom hlau, tab sis ob qho ntawm feem ntau yog stainless hlau thiab carbon hlau.

Tej zaum lawv yuav zoo tib yam, tab sis muaj qee qhov sib txawv tseem ceeb ntawm ob. 

Stainless hlau tseem hu ua inox steel thiab tiv taus staining los ntawm corrosion.

Qhov no yog vim nws muaj qhov tsawg kawg nkaus chromium cov ntsiab lus ntawm 10.5% los ntawm huab hwm coj.

Cov chromium no tsim ib qho kev thaiv ntawm cov hlau thiab oxygen, tiv thaiv nws los ntawm xeb. 

Carbon steel, ntawm qhov tod tes, yog tus cwj pwm los ntawm cov ntsiab lus siab carbon, feem ntau txog li 2.1% ntawm nws qhov hnyav.

Nws tsis muaj cov khoom tiv thaiv corrosion zoo ib yam li stainless hlau, yog li nws tuaj yeem xeb thiab corrode thaum raug dej.

Nws tseem muaj zog thiab nyuaj dua li cov hlau tsis muaj steel, uas yog vim li cas nws feem ntau siv rau hauv ntaj, riam, thiab lwm yam riam phom. 

Hauv seem tom ntej no, kuv yuav mus hla qhov sib txawv ntawm ob hom Japanese hlau uas riam yog ua los ntawm.
