Niobium Nplhaib Description
Niobium rings yog hollow, ncig daim hlau thiab tuaj yeem ua tau raws li qhov ntau thiab tsawg. Niobium rings tuaj yeem ua raws li qhov dav, tuab, thiab lub nplhaib txoj kab uas hla. Niobium rings tej zaum yuav muaj qhov kev cai zoo thiab yuav qhib lossis kaw. SSC tshwj xeeb hauv kev tsim cov purity siab zoo zoo li niobium rings. SSC muaj kev cai rings nrog annealed los yog nyuaj tempers thiab yuav ua tau raws li feem ntau ntawm Mil spec lossis ASTM tus qauv. Ntxiv nrog rau cov ntshiab niobium thiab cov qauv alloys, SSC kuj tseem tshwj xeeb hauv cov hlau nplaum tiv thaiv corrosion, cov ntawv thov kub, thiab cov qauv kev cai thiab cov ntaub ntawv suav nrog kev cai sab hauv thiab sab nraud qhov ntev thiab threading. SSC kuj tsim niobium li qws, ingot, hmoov, daim, disc, granules, hlau, thiab nyob rau hauv cov ntaub ntawv compound, xws li oxide.
