Q: Dab tsi yog "Yield Strength" (piv txwv li, 245 MPa lossis 35,000 psi)?
A:Qhov kev ntxhov siab uas cov khoom pib deform plastically (mus tas li). Nws yog ib qho tseem ceeb tsim parameter rau siab ntim.
Q: Dab tsi yog "Tensile Strength"?
A:Qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus thaum ncab ua ntej tawg.
Q: Vim li cas "Charpy Impact Testing" tseem ceeb rau qee cov kav dej?
A:Nws ntsuas cov khoom toughness thiab tsis kam rau nkig tawg ntawm qhov kub thiab txias, uas yog qhov tseem ceeb rau cov kav dej hauv qhov chaw txias.
Q: Dab tsi yog qhov tsis zoo ntawm cov pa roj carbon steel yeeb nkab hauv ntau qhov chaw?
A:Nws muaj kev cuam tshuam rau corrosion (rusting) thaum raug ya raws thiab oxygen lossis lwm yam xov xwm corrosive.
Q: Dab tsi yog "Galvanized" yeeb nkab?
A:Cov yeeb nkab carbon steel coated nrog ib txheej ntawm zinc (los ntawm kub-dip lossis electroplating) los muab kev tiv thaiv corrosion.
