Stainless Hlau Round Bar Nrog Zoo Zoo

Hlau (Fe): yog cov hlau tseem ceeb ntawm stainless hlau;

Chromium (Cr): yog lub ntsiab ferrite tsim cov ntsiab lus, chromium ua ke nrog oxygen tuaj yeem tsim cov tshuaj tiv thaiv corrosion-resistant Cr2O3 passivation zaj duab xis, yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm stainless hlau kom muaj kev tiv thaiv corrosion, chromium cov ntsiab lus tsub kom lub passivation zaj duab xis kho lub peev xwm ntawm hlau, cov ntsiab lus stainless hlau chromium dav dav yuav tsum siab dua 12%;

Cov pa roj carbon (C): yog qhov muaj zog austenite tsim, tuaj yeem txhim kho lub zog ntawm cov hlau, ntxiv rau cov pa roj carbon monoxide kuj muaj qhov cuam tshuam tsis zoo;

Nickel (Ni): yog lub ntsiab austenite tsim cov khoom, tuaj yeem ua kom qeeb ntawm cov hlau thiab kev loj hlob ntawm cov nplej thaum cua sov;

Molybdenum (Mo): yog cov carbide tsim cov khoom, cov carbide tsim yog qhov ruaj khov heev, tuaj yeem tiv thaiv kev loj hlob ntawm austenite thaum rhuab, txo cov superheat rhiab heev ntawm cov hlau, ntxiv rau, molybdenum tuaj yeem ua rau cov zaj duab xis passivation ntau ntom thiab khoom, yog li zoo txhim kho stainless hlau Cl- corrosion kuj;

Niobium, titanium (Nb, Ti): yog ib qho muaj zog carbide tsim cov ntsiab lus, tuaj yeem txhim kho cov hlau tsis kam rau intergranular corrosion. Txawm li cas los xij, titanium carbide muaj qhov cuam tshuam tsis zoo rau qhov zoo ntawm cov hlau tsis zoo, yog li cov hlau tsis muaj hlau nrog cov kev xav tau saum npoo siab feem ntau txhim kho los ntawm kev ntxiv niobium los txhim kho kev ua haujlwm.

Nitrogen (N): yog lub zog austenite tsim, tuaj yeem txhim kho lub zog ntawm cov hlau. Tab sis kev laus tawg ntawm stainless hlau muaj kev cuam tshuam ntau dua, yog li cov hlau tsis huv hauv stamping lub hom phiaj kom nruj tswj cov ntsiab lus nitrogen.

Phosphorus, sulfur (P, S): yog ib qho teeb meem nyob rau hauv stainless hlau, corrosion kuj thiab stamping stainless hlau yuav muaj kev cuam tshuam tsis zoo.
