ASTM A500 ndi machubu ozizira opangidwa ndi chitsulo chosakanizika komanso osasunthika opangira machubu owotcherera, opindika, kapena otsekeredwa ndi mlatho ndi zomangira ndi zolinga zake zonse.
Gulu C chitoliro ndi mmodzi wa giredi ndi mkulu zokolola mphamvu zosachepera 345 MPa ndi kumakoka mphamvu ya osachepera 425 MPa.
Ngati mukufuna kudziwa zambiri zaASTM A500, mutha kudina kuti muwone!
ASTM A500 imayika chitoliro chachitsulo m'magulu atatu,kalasi B, giredi C, ndi giredi D.
CHS: Zigawo zozungulira zozungulira.

Chitsulocho chidzapangidwa ndi chimodzi kapena zingapo mwa njira zotsatirazi:zofunika mpweya kapena ng'anjo magetsi.
Chophimbacho chidzapangidwa ndi aopanda msokokapena kuwotcherera ndondomeko.
Machubu opangidwa ndi welded ayenera kupangidwa kuchokera ku chitsulo chopindika chathyathyathya ndi njira yamagetsi-resistance-welding process (RW).Cholumikizira chachitali cha matako a chubu chowotcherera chidzawotcherera ku makulidwe ake m'njira yoti mphamvu ya kapangidwe ka gawo la chubu likhale lotsimikizika.
ASTM A500 Gulu C imatha kuchepetsedwa kapena kuchepetsedwa kupsinjika.
Annealing imatheka potenthetsa chubu mpaka kutentha kwambiri kenako ndikuziziritsa pang'onopang'ono.Annealing imapanganso microstructure yazinthu kuti zikhale zolimba komanso zofanana.
Kuchepetsa kupsinjika kumachitika potenthetsa zinthuzo kuti pakhale kutentha kocheperako (nthawi zambiri kutsika poyerekeza ndi kutsekereza) kenako kuzigwira kwakanthawi ndikuziziziritsa.Izi zimathandiza kupewa kupotoza kapena kuphulika kwa zinthu panthawi ya ntchito zotsatila monga kuwotcherera kapena kudula.
Kuchuluka kwa mayeso: Zitsanzo ziwiri za chitoliro chotengedwa pagawo lililonse la zidutswa 500 kapena kagawo kakang'ono kake, kapena zitsanzo ziwiri za zinthu zopindika zafulati zotengedwa pagawo lililonse la zidutswa za zinthu zopindika.
