Dab tsi yog cov yam ntxwv ntawm 1018 carbon steel txias-rolled round bar?

Dab tsi yog cov yam ntxwv ntawm 1018 carbon steel txias-rolled round bar?
Tensile zog 85,000 psi, yield zog Ntau dua los yog sib npaug rau 70,000 psi, elongation Ntau dua los yog sib npaug rau 28%, Brinell hardness 167.
Qhov ntsuas qhov tseeb yog li cas thiaj kuaj tau?
Siv calipers thiab micrometers los ntsuas diameters thiab roundness, uas yuav tsum tau raws li tus qauv tolerances.
Qhov kev ntsuam xyuas qhov zoo li cas suav nrog?
Visually los yog instrumentally tshuaj xyuas qhov tsis xws luag xws li khawb, pitting, tev, thiab nplai. Roughness yog ntsuas raws li qhov tsim nyog.
Internal quality tswj li cas?
Kev ntsuam xyuas metallographic yog siv los soj ntsuam cov khoom sib xws thiab txheeb xyuas cov kev suav thiab qhov khoob. Qhov sib piv ntawm dov txo yuav tsum siab dua los yog sib npaug rau 3: 1.
Dab tsi txiav txim siab qhov corrosion kuj ntawm txias -rolled round bar?
Nws yog feem ntau txiav txim siab los ntawm cov khoom muaj pes tsawg leeg (piv txwv li, stainless hlau muaj chromium thiab npib tsib xee, tsim cov oxide zaj duab xis), tab sis qhov zoo ntawm qhov chaw kuj ua lub luag haujlwm.
